INTRODUCTION

| |
Donkeys are amongst
the oldest companions of man. They are the most simple and unselfish members
of the equine family. It is a very hardy animal and can work incessantly,
with little rest and on poor forage. It is mainly used as a pack animal
and is particularly known for its sure footedness. Donkeys do well in
hot and semi arid areas. While people come into contact with horses and
bullocks everyday, few people realise the importance of donkeys in India.
Our houses are built with their help, all our mining is done with their
help, our clothes are washed with their help. They transport people and
goods across rugged and hostile terrains. They are even used by the armed
forces. They are seen carrying people to religious spots or working in
brick kilns and quarrys. These are just some of the ways in which the
donkeys are a major asset to human lives.
However we ignore their physical needs. A donkey works the whole day.
But at night, his owner hobbles him by tying his legs together painfully,
tightly and then leaves him in the city to find his own food. Most donkeys
lead short lives of 3-4 years even though their natural life span is over
30 years. This is because they are not fed, watered or properly treated
for their injuries. They are overloaded and made to work long hours under
very stressful conditions. Vets are not trained to treat donkeys, which
require a very specialised form of medicine. Instead they are treated
– if at all – with horse medicine. India’s first donkey treatment centres
have been opened only recently in Gurgaon and Vadodara. It has been realised
that a working animal becomes a far more useful resource if it is treated
humanely and its needs are attended to.
Indian Donkeys
The type of donkey to be found in India and Nepal is the Kiang (shoulder
height about 150 cm, weight 300 – 500 kg). Rajasthan has the maximum number
of donkeys . Uttar Pradesh comes next, followed by Gujarat, Tamil Nadu
and Haryana. The two types of donkeys, small grey and large white, are
common. The small grey donkey is found in most parts of the country. Its
colour is dark grey with zebra stripings on the limbs, neck and quarters.
The large white type is mostly found in the Kathiawar region of Gujarat
State. It is generally light grey to almost white in colour.
The Indian wild ass population is mainly confined to the little Rann of
Kutchh, a unique salt desert – wetland ecosystem in the state of Gujarat.
Very little is known about these Indian wild asses which are locally called
Khur and Ghorkar. The Rann of Kutch is the only habitat of the Indian
Wild Ass and is commonly known as the Indian Wild Ass Sanctuary, which
is the largest wildlife for donkeys sanctuary in the world. The Indian
Wild Ass is one of most endangered species in the world.
Interesting Facts about Donkeys
Here are some interesting bits of information
The placement of a donkey's eyes allows them to see in an arc of 350 degrees.
Their blind spot is the 10 degrees directly behind them. They are very
far-sighted and cannot focus on objects 15 feet or closer to them. To
see the ground directly beneath their nose they must tilt their head down
and tuck their nose toward their chest. Because their vision is motion
oriented, they cannot see a predator if it is standing still, but they
can see an object move 1/2 mile away.
They have very keen hearing, and can hear several octaves higher and lower
than a human. It has been documented that donkeys “rumble” to each other
in tones too low for the human ear to detect.
Donkeys also have a very keen sense of smell. They can smell odours on
your hands and clothes so it is not recommended to pet a dog on your way
to the barn. They can also detect the scent of treats if you carry them
in your pocket. They smell their food before they eat it and if it has
a peculiar odour they will not eat it.
Because nature did not design a donkey for speed, his survival depends
on trusting the other herd members to be alert to any danger of predator.
It is this instinct to be co-dependent that allows donkeys to adjust so
quickly to captivity and to training.
The various uses of Donkeys Donkeys love people.
The best reason of all to have donkeys is for pets. They love attention
and they want to be part of the family.
• Donkeys will protect other livestock. Once a donkey has bonded with
a herd of sheep, goats, cattle, etc., the donkey will chase predators
(dogs, etc.) that may bother the herd. In fact, donkeys are such good
protectors of stock that they are used to protect stock from leopards
and cheetahs. Just one bray from a guard donkey is usually enough to send
would-be predators or intruders heading away.
• Donkeys can assist with halter training other animals. You can use a
donkey to teach cattle, horses, other donkeys, etc., to be lead with a
halter and rope. Attach a rope between the animal to be taught and the
donkey by using a special extra collar for the donkey. The donkey is so
strong he can lead the other animal easily. It is not recommended to leave
the animals tied together for very long periods of time, and NEVER leave
them unsupervised.
• Donkeys can be ridden or be used to pull carts. Many donkeys can be
ridden under saddle or trained to pull a cart in harness. (Note: No donkey
under 3-years of age should be used to carry weight. Their bones need
to be fully developed and grown before they can carry a weight load. Moreover
a donkey should not be made to carry more than 50 kg at a time.)
• Companion Animals. A donkey makes a good companion animal for
nervous animals or young horses or cattle that are being weaned. The donkey’s
kind and calm disposition seems to settle down the nervous animal and
take their mind off an unpleasant situation.
• Cross Breeding. Donkey jacks can be bred to horse mares and the resulting
offspring is a mule. Donkeys can also be crossed with zebras.
• Pack Animals. Even though they are smaller than horses, adult
donkeys can carry a large amount of cargo for their size due to their
build and bone structure. However please note the word of caution in the
point that donkeys can be ridden above.
• Therapeutic Riding Programs. The gentle disposition of a well-trained
donkey makes them excellent for use in therapeutic or riding programs
for the handicapped. Donkeys seem to make friends with people easily,
and therapeutic riding programs can really help in the treatment of muscular
diseases or disorders, back injuries, or riding programs for physically
or mentally handicapped persons. Though these riding programs have started
abroad, they are yet to begin in India.
How are Donkeys
ill - treated
Donkeys in India are misused or ill-treated and worked in the most appalling
conditions. The work that the donkeys are made to do varies depending
on the terrain. It dictates whether they are mainly used as pack animals,
draught animals or more recently as animals for tourists.
Overloading of pack animals is a common problem in India and very tempting
to a poverty stricken owner, often undernourished himself, hoping that
the donkey can take a load in one trip rather than two. Donkeys are so
willing and biddable that they patiently accept crate after crate, shovel
after shovel of sand, brick after brick until their legs actually buckle
or they are forced to their knees. This load constantly rubs on the donkey’s
spine and ribs causing cuts, sores and bruises. Since the donkeys are
usually the only source of income for their owners, they never manage
to get adequate rest even after they are sick or maimed, as this means
a loss of income for the owner for that period. Their sickness and wounds
are treated by the owners themselves, in spite of them having very little
knowledge about medicines. Donkeys that work in quarries often fall from
cliffs because they are overloaded and unbalanced. Many hurt their spines
and break their legs but are made to continue working.
In many parts of India the donkey is used as a draught animal i.e. it
is used to pull a cart or some kind of ploughing equipment. This is done
because a donkey’s pulling power is much greater than it’s drawing power.
But this is true only when the harness fits and when the cart is balanced
correctly. Unfortunately these conditions rarely occur and the common
thing is that a far too heavy cart and a tack that is more suitable for
a horse or an ox, is adapted with pieces of wire to fit the donkey. This
causes extreme distress to the donkey. Sometimes, especially while going
uphill, the donkeys even die as excessive weight is taken by them on the
band around their neck. This is because the strain cuts off the air supply
of the donkey and chokes him to death. In rural areas, the donkeys are
even used for ploughing.
Donkeys are also used in the tourist trade to carry tourists to religious
spots. No effort is made to match the rider's weight with the size of
the donkeys. As a result it is a common sight to see a bulky man riding
a small donkey.
Apart from this, since the donkey owners themselves live in slums and
crammed colonies, they have no place for keeping their donkeys. Most of
the time they are kept by the roadside under the open sky, exposed to
the sun, rain and vagaries of the nature. Under these conditions, the
donkeys have no option other than to sleep in the mud and the slush. Moreover,
the feet of the donkeys are hobbled by the neighbourhood blacksmith who
does not know the difference between a living creatures legs and a log
of wood. The instruments used are crude and the iron nails used are never
sterilised. The entire process of fixing it is unscientific and can cause
infection.
Even after a donkey completes its day’s work, it is not fed by his owner.
To prevent him from straying too far, its legs are tied together and then
it is left to hop across roads and barren lands looking for its own food.
No wonder most of the donkeys die before they are 5 years old without
any questioning as to the cause of death. What happens to a donkey which
becomes unfit for pulling the cart because of injury, ill health? They
are sold to the butchers.
All these are only a few of the ways in which donkeys are being ill -
treated.
Prevention of Ill– treatment of Donkeys
You must have seen donkeys often being ill-treated by their owners. But
as the common man is often himself oblivious of the laws protecting these
animals, he is able to do little to help the poor distressed donkey. Hence
it is very important for everybody to have a basic knowledge about the
laws protecting donkeys.
If you come across anyone who ill- treats his donkey by overloading and
does not give him proper food, you can take severe action as under Section
11 of the Prevention of Cruelty to Animals Act 1960, beating, kicking,
overriding, torturing or causing any animal pain or suffering, using any
animal for work when it is wounded or unfit, by any other person or the
owner, is a punishable offence. The penalty is a fine that may extend
to Rs. 1000/- or imprisonment for a term which may extend for a term of
three months or both
Moreover there are some general conditions which have to be followed for
the use of draught and pack animals – No person shall use or cause to
be used any animal for drawing any vehicle or carrying any load :-
i) For more than nine hours in a day.
ii) For more than five hours in a day continuously without a break for
the rest of the animal.
iii) In any area where the temperature exceeds 37 deg. C (99 deg F) during
the period between 12.00 noon and 3.00 p.m.
iv) Animals should be disengaged after work – No person should continue
to keep or cause to be kept in harness any animal used for the purpose
of drawing vehicles, after it is no longer needed for this purpose.
v) Use of spiked bits prohibited – No person shall, for the purpose of
driving or riding an animal or causing it to draw any vehicle or for otherwise
controlling it, use any spiked stick or bit, harness or yoke with spikes,
knobs or projections or any other sharp tackle or equipment that causes
or is likely to cause bruises, swellings, abrasions, or severe pain to
the animal.
vi) A donkey should not be made to carry more than 50 kg. 50 kg would
be approximately 25 – 30 bricks of standard size.
vii) Hobbling the legs of donkeys is illegal.
Now whenever you see a donkey being ill – treated, you can stop him right
there and inform the owner about the rights of the animal and the laws
framed for its protection. If the owner still does not adhere to the laws,
you can get a policeman to help.

SHELTERS FOR DONKEYS
|
| |
A donkey
can not handle extreme cold as well as horses can. Donkeys need to be
able to escape from harsh elements - cold as well as heat. An adequate
shelter goes a long way in making sure your donkey stays comfortable
in any condition.
It is a good idea to ensure that your shelter faces away from the prevailing
wind and not directly into the sun which might cause it to heat up in
the summer. Also make sure you do not locate it in a low spot that would
become impassable with mud during certain times of the year. Use wood
shavings if locally available to keep the shelter and the surrounding
area a dry and comfortable place for the donkey to be in.
Donkeys do not seem to mind sharing their space with each other on most
occasions.
Picking up manure from the shelters and pens is important. If you cannot
haul it away daily, pick an out of the way spot for your manure pile,
and either spread it in the hottest part of summer or advertise it for
fertilizer. Urine spots must also be cleaned as the build up of the
smell of amonia can harm the lungs of the equine. Picking up faecal
matter regularly means less smell, flies, and parasite contamination.
You and your donkey will be much happier if his home is clean and neat.
A shelter is necessary for the comfort and health of any donkey. They
dislike water, whether it is under their feet or falling from the sky
and most do their best to avoid it. This is because their desert coat
seems to soak up moisture rather than repel it. A damp coat that is
never able to dry encourages fungus and other skin infections. A donkey
needs to be kept in a clean, dry, and prote-cted condition. It should
be kept in a healthy environment and needs to be carefully managed and
handled. All these points are facilitated with good stabling. A list
of principle essentials for stables are as under :
– A reasonably uniform temperature, eliminating extremes as far as possible.
– A dry atmosphere and freedom from condensation on the surfaces of
the building.
– Generous air movement and ventilation without draughts.
– Sound, dry flooring.
– Good drainage.
– Adequate lighting, both natural and artificial.
– Good feeding and water arrangements.
Environmental requirements
In order to provide the correct climatic environment in the donkey’s
shelter and reduce the likelihood of disease, it is essential to have
a basic understanding of the donkey’s physiological needs. The principle
elements of the climatic environment which affect the donkeys are ambient
temperature, relative humidity, ventilation rate and air movement.
Ambient temperature
A donkey can easily tolerate a wide range of ambient temperatures, e.g.
0 – 30 degrees C without harm, depending on the degree to which the
individual animal has been allowed to acclimatize, and provided the
atmosphere is free from damp and draught.
Relative humidity
The burden on the donkey, especially on the respiratory system, is intensified
if the air is damp (i.e. the relative humidity is near saturation).
The worst conditions are those of low temperature and high humidity.
Ventilation rate and air movement
Ventilation rates are based primarily on two points – the maximum rate
to keep the shelter cool in hot weather, and the minimum rates to eliminate
from the environment, even in the coldest weather, the humidity arising
from the animals’ exhalation and the evaporation of their excreta. Provided
the minimum requirements are observed, there will be no problems with
gaseous exchange.
The following table summarizes the range of climatic environmental requirements

Building
and Ventilation
It is essential that the buildings are well insulated to ensure ventilation.
The simplest ventilation technique, used since animals were first housed,
relies on three natural forces:
1) Stack effect i.e rising warm and stale air.
2) Aspiration i.e wind force across the roof of the building sucking
air out.
3) Perflation i.e.air blown from side to side and end to end of the
building.
A roof extracting trunk or chimney provides the stack effect. Fresh
air inlets replace the stale air and should be situated near the wall
to give a uniform in - flow of the air. The chimney may be designed
in such a way that the air is allowed to flow freely across the top.
Such a chimney encourages the aspiration effect. The perflation effect
is ensured if there are inlets on both sides of the building to give
a thorough draught when required.
Each stable should have its quota of half doors and windows, preferably
of double glass, which can be opened for extra air flow during hotter
weather.
Alternatively, the donkeys can also be kept in covered yards. These
yards can have gaps of about 17 mm in the roof to provide good ventilation.
The approximate size of the box in which the donkeys are to be kept
is 3.3 m x 3.3 m (10 ft x 10 ft). The additional facilities that must
be a part of the layout of the stable are:
Isolation box
It is advisable to have at least one isolation box for sick animals
of suitable size. Such a box is essential if any animal is suffering
from any contagious disease, but is also useful for donkeys requiring
special treatment. The box or boxes must be quite separate from the
rest of the establishment. The box should be readily accessible and
the donkeys should not only be able to see people, and be seen, but
should also be in the sight of other animals. It is
also preferable to have the isolation room built larger than the size
of ordinary boxes.
The feed room
The feed room is used for storing fodder which is for immediate use,
as opposed to the feed store, where the long term supplies are kept.
Its dimensions and that of the store will depend on the size of the
establishment. Daily feeds are prepared in this room and it will contain
separate bins for individual feeds e.g. oats, bran, barley etc. There
should also be a sink with hot and cold water and a tap to supply drinking
water. In large establishments there, there should be chaff cutters
and other machinery for the preparation of the feed.
The feed store
The feed store usually adjoins the feed room and is also close to the
storage areas for hay and straw. The store will contain feed in bulk
bins, sacks and bags. A convenient arrangement is to build a store above
the feed room so that the large quantities of feed can be moved down
as and when needed. The movement of the food up to the store will only
be done occasionally.
Hay and straw stores
A totally dry building with hard, dry floors and free ventilation throughout
is required for the storage of all bedding and feeds. Wet, damp and
dusty bedding must be avoided at all costs in order to keep the risk
of respiratory diseases and allergies to the minimum. The hay and straw
barn must ideally be in close proximity to the feed room and the feed
store, but also situated in a place suitable for offloading bales from
delivery vehicles. Besides as well as storing hay and straw, this barn
may be required for other forms of litter storage, such as peat, wood
shavings, saw dust or shredded paper.
Being in a position to cope with bulk storage on site allows the purchase
of good hay and straw at a time when the prices are low and supplies
are readily available – essentials for good stable management.
Tack room and washing and cleaning facilities
The tack room is the most important service room in a group of stables.
The room must be fitted with brackets, shelves and cupboards to take
all the equipment. Closed cupboards and/ or chests are useful for storing
blankets and other clothing. This room should also incorporate washing
and cleaning facilities.
Manure storage
This must be within easy access to the boxes but also with good road
access for offloading. If it is too close to the boxes, it may create
an unpleasant smell and increase the fly menace. The manure store should
have a concrete base with a fairly steep fall to ensure better drainage.
The more frequent the manure disposal, the better it is.
Fences and gates
The whole establishment will require good fencing for the protection
and safety of the donkeys and the staff. Fittings and fixtures
Mangers
Mangers for feeding are usually placed about 0.7 m (2 ft) above the
floor. They can be made from vitreous enamel, galvanized steel, stainless
steel or timber with salt glazed channels and can be fitted either along
the face of the wall or in the corner. Stainless steel may be a little
expensive but it lasts longer and is easy to clean. A manger may be
combined with a hay rack or a water trough but the latter combination
is not recommended as the food tends to foul the water trough. A manger
should usually be fitted on the wall of the box opposite the door. It
is the best position for the animal and also for the safety of the operator.
Hay racks
Hay racks can either be combined with a manger or be entirely separate.
The hay rack must be securely fixed to the wall. If the rack is positioned
at a lower level, the donkey is able to eat in a normal position. But
if the rack.
is placed higher, say about 1.3 m (4 ft) from the floor, there is danger
of dust and seeds entering the donkeys eyes.
Water containers
Every stall or box requires fittings for clean, fresh water. The water
may be provided in a bucket or an automatic water trough may be fitted.
If buckets are used, there should be a proper bucket holder secured
to the wall. Troughs containing 2- 3 gallons are made of stainless steel
or galvanized steel and incorporate a ball valve, drain tap and overflow.
Rings
Rings are required in boxes and stalls for tying up donkeys. Two or
three rings per stall or box are usually adequate. One ring should be
placed at around 1m (3 ft) from the floor for tying the donkey to the
manger. Another ring should be put at 1.5-1.55m (5- 5.5 ft) from the
floor for general tying up purposes.
Electrical points and lighting
At least one electrical point is needed in each box and two points are
needed for two lights at each side of the box. The best lights are those
with watertight, bulkhead covers, firmly secured to the wall and fitted
with heavy prism glass or strong grilles. They should be placed at 1.6
– 1.9 m (5 to 6 ft) from the ground.
Hygiene
To ensure good health for the donkeys, a regular programme for cleaning
and disinfecting must be followed in the shed. Five principal procedures
need to be followed in this regard:
• The accommodation should be emptied of all the donkeys.
• All the dirt should be cleared out and removed from the premises.
• Wash the shed with a heavy duty detergent sanitizer.
• Soak in a safe disinfectant. A safe disinfectant is one that is based
on iodophors, chlorine, organic acids and aldehydes.
• Dry out before replacing beddings and the donkeys. The principal failure
in cleaning and disinfecting techniques is to leave organic materials
in cracks and crevices. This is where bacteria and parasites persist.
Also rodents and insects act as serious carriers of infection and must
be exterminated.
Moreover an attempt should be made to prevent flies in the shelter as
they are not only major irritants but can even cause disease in the
donkey. Here are some helpful hints to prevent flies in the shelter:
• Put up tarpaulin (water proof sheets made of canvas) at your barn
or shelter doors to darken the interior. Flies like sunshine and avoid
darkness. The tarpaulin should be just above ground level
• Garlic does help make the donkeys distasteful to most flies , but
does not repel flies. It can be applied on the donkey as a paste.
• Place a fan to blow above their heads or just above ground level in
areas of the barn that you can not darken. Flies avoid fast moving air
currents.
• Manure should be regularly picked up and removed from in and around
the barn and in areas where donkeys congregate.
• A water-based fly spray is less irritating to the donkey's skin. Coat
their hair but do not saturate.
• Recipes for homemade fly sprays:
(i) 1 cup of fabric softener juice of one lemon (or 2 tablespoons of
real lemon concentrate)
4 tablespoons of Listerine
5 cups of water Spray or wipe on.
(ii) 1 cup of fabric softener 1/4 cup of lemon-scented dish detergent
1/4 cup of white vinegar
5 cups of water
Spray or wipe on
However, some of these repellents may turn out to be a costly affair.
Hence, especially in India, most of the donkey owners use neem oil or
burn cow dung to repel flies. However, burning cow dung is not recommended
as the smoke can fill up the shed and cause suffocation.
Donkey Shelter check list
Ensure that your donkey shelter has the following:
• Equine Worming Paste
• Wound Dressings - Bandages, swabs, gauze etc.
• Animal Medicines - Tetanus Toxoid Vaccine, antiseptics, lice control
preparations
• Grooming Tools - brushes, hoof picks
• Donkey rugs, fly veils
• Vitamin/mineral supplements - Sulphur, Dolomite, seaweed, molasses
• Rakes, wheelbarrows and manure scoops
• Bales of hay .

FEEDING
|
| |
Donkeys require
a highly nutritious diet containing carbohydrates and fibre. While carbohydrates
provide the donkey with essential energy, fibres are responsible for stimulating
muscle contractions in the gut and preventing impactions by breaking up
of mass gut contents. Fibre also serves to dilute the more readily fermentable
material, and encourages the donkey to eat more slowly, which helps to
prevent digestive disorders such as colic.
The donkeys feed must also contain proteins, vitamins and minerals. The
excess intake of some minerals is as harmful as their deficiency. But
perhaps the most important nutritional requirement for donkeys is that
of water. An adequate supply of clean, fresh water is required to replace
the water lost from the body in the form of urine, faeces, sweat, evaporation
from the lungs and the skin and in productive secretions such as milk.
Water intake may be reduced if the grazing is lush but the most important
factors that increase water intake are lactation (by 50 – 70 % at peak
lactation), environmental temperature and exercise (20 – 300 % depending
on the level of activity).
Feedstuffs
There are two main types of feedstuffs available for donkeys, forages
and concentrates. Forage such as grass or hay provide both nutrients and
roughage. However this may not be sufficient to meet the demands of most
working donkeys. These donkeys require additional concentrates or “hard
feeds”. Apart from working donkeys, pregnant, lactating, growing and elderly
donkeys also require concentrates in their food.
Forage
Grass is the natural feedstuffs for donkeys . Hay is usually produced
from forage(usually grass) crops by cutting, drying in the field and baling.
It should not usually be fed before six months after fermenting. This
is because new hay is still green and fermenting and can cause colic in
donkeys. However very old hay may become mouldy and its nutritional content
may also deteriorate overtime. This type of hay should be strictly avoided.
The hay used for feeding should also be free of any toxic weeds that may
grow locally.
Straw is produced from the stem of the cereal after the grain has been
removed. It has a high fibre content and a lower nutritive value than
hay. Good clean oat and barley feeding straws are useful feeds for the
donkeys and can be used to increase the fibre content of the rations.
However, straw as the only forage source is unlikely to meet the donkey’s
nutritional requirements without some sort of supplement.
Chaff is chopped hay or straw and may be used to add bulk to the donkey’s
feed. Molasses is often added to produce molassed chaff, which increases
the palatability and fibre of the diet, and reduces the dust.
Cereals
Oats are the traditional and the most widely used cereal that may be fed
whole or after processing (crimped or rolled). Processed oats improve
digestibility and can be used to feed young donkeys with dental problems.
However the nutritional value of oats is reduced during processing. Oats
have a higher fibre and lower digestible energy content than other cereals.
Hence it is considered to be a relatively safe feed. But oats may cause
a stimulant effect called “hotting up” in some donkeys and this may make
them less suitable for riding.
Barley has a thick fibrous hull which is relatively indigestible
and hence it has to be cooked or processed to rupture the seed case before
feeding. The energy content of barley is slightly higher than oats but
less than that of maize.
Maize (corn) is a high energy feed which may be fed whole or after
processing (e.g. flaking). If fed whole, however, the grains are hard
and the donkeys with poor teeth may find them difficult to crack. Maize
is higher in digestible energy but lower in proteins than oats. Since
maize is energy dense, it is more useful for feeding thin donkeys or those
in hard work , but only small quantities may be required.
Wheat has small , dense grains with a high gluten content, which
tends to form an indigestible pasty mess in the stomach if fed whole.
For this reason, wheat is not commonly used for feeding donkeys.
Bran is a milling by product of wheat, which has a relatively
low nutritive value but a high fibre content. Bran is relatively deficient
in calcium and rich in phosphorous. Excessive feeding may cause skeletal
deformities due to nutritional secondary hyperparathyroidism (big head,
bran disease, Miller’s disease). These problems may further lead to laminitis
as well.
Supplementary feeds
The salt requirements of the donkeys varies according to their physical
activity, and it is recommended that all donkeys should have free access
to a salt lick ( either as a block or in loose granular form). Trace mineralised
salts, containing added iodine, copper, cobalt, manganese, zinc and sometimes
selenium may be useful in areas where these elements are deficient in
the soil.
Vitamin and mineral supplements are added to the feed of the donkeys to
increase the amount of a specific nutrient or nutrients in the diet.
Amount of Feed
The amount of feed should be determined by the weight of the donkey. Youngsters
under the age of two and older donkeys that are more than 20-years-old
have beenfound to do well on rolled oats or a 50 per cent rolled oat and
50 per cent rolled barley mix. Adult donkeys over the age of two years
do well on good quality, clean whole oats.
Adult donkeys in good condition will eat the same amount of hay, plus
the ration of concentrates mentioned above. Naturally the amounts fed
will vary with the size and condition of the donkeys. A rough guideline
is to feed a total weight (hay plus grain ration) of 1 kg of feed per
50 kg of body weight (two pounds of feed per hundred pounds of body weight).
For example:
A 450 lb donkey
• at rest - approximately 4 kg (9 lb) total feed (hay plus grain) daily.
• at work-approximately 5kg(11.25 lb) total feed daily
The more hard work required, the greater is the amount of grain usually
given providing the donkey does not become too energetic and hard to handle.
For example:
A 450 lb donkey
• at rest - 0 to 1 lb grain plus 7-8 lb hay daily.
• at work - 1 to 2 lb grain plus 9-10 lb hay daily.
General guidelines for feeding donkeys are
1) Donkeys should be fed at least twice a day, at regular intervals, since
the digestive system and the hormonal systems of the donkey are adapted
to the frequent intake of small amounts of food.
2) Changes in the feeding regime for donkeys ( such as the changes in
or the introduction of concentrates in the diet) must always be carried
out gradually. A sudden change in the feed can lead to serious nutritional
disorders.
3) The amount of feed should be determined by weight and not by volume,
since energy density varies between feeds and even between batches of
the same feed.
4) Avoid dusty or mouldy feeds which can give rise to respiratory disease
or intestinal disorders.
5) Access to salt or mineral licks is advisable to account for variations
in individual requirements.
6) Clean water should be available at all times. However when the donkey
is hot after exercise the donkey should not be allowed to drink water
immediately.
7) Regular worming and dental checkups are necessary to enable the donkey

GENERAL HEALTH CARE
|
|
If the donkey
is thin, its ribs, spine and tuber coxae are very prominent and its coat
is dull then the donkey is very sick and needs to be taken for treatment
at once. If its spine is prominent and its coat is dull then his condition
is serious but not an emergency. The ideal situation is when the spine
is not protruding and its coat and skin is supple and shiny. Its stomach
should not protrude and its muscles should be firm.
Grooming
Donkeys enjoy being groomed. Brush them with a fairly stiff brush in the
direction in which the hair grows. Be gentle with the ears, do not twist
or hold them tightly.
The following is the method for grooming a donkey:
1) Fit the head collar and the leadrope. The harness should be one which
does not harm the donkey by rubbing against the skin. An ideal harness
is shown in the diagram above.
2) Tie your donkey up using the quick release knot.
3) An assistant should stand at its head during the first grooming sessions.
4) Always start from the near (left) side and go in sequence to pick out
the feet and the area by the hoof pick
Hoof pick
A hoof pick should have a bunt end. If the point is sharp, it could cut
the sole of the foot, or puncture the sole if the horse steps on it. A
hoof pick is a vital grooming tool. Keep it where you will find it.
5) Start with the dandy brush to brush the coat in the direction of the
hair from the near side and brushing towards the tail.
6) Use a body brush for the face, legs, belly and the tail.
7) A plastic curry comb to clean the body brush can also be used to clean
the coat as the dandy brush.
A metal curry comb. This brush should be kept free of hair to maintain
its effectiveness.
8) A rubber curry comb is useful if the donkey is moulting- use it in
a circular way to remove any lose hair from the coat.
Curry combs
Plastic and rubber curry combs are used for removing dirt, especially
dried mud. They can be used directly on horses that can tolerate them,
al-though care should be taken when using them on hor-ses with a thin
coat or sensitive skin
Ensure that you remove all prickly thorns, seeds which are stuck in the
donkey's hair. They can result in injuring the donkey and creating of
body sores
Watch for the donkey that rubs its coat, especially at the tail head -
it may have lice.
Lice
It is important to keep the donkey free of lice so that it can have a
good skin and is free from itching.
Lice seems to build up through the winter and makes the donkey very itchy
and uncomfortable. If he starts scratching himself against trees or gate
posts, or biting constantly at his rump, you can be sure that he is lousy.
If you find that the louse powder designed for horses does not work, wait
for a warm day and give your donkey a good wash down with Asuntol. This
can be purchased from the local chemist. You will need to do this towards
the end of winter in February/March.
Teeth Care
After a donkey reaches about 10 years of age (or sooner if you observe
chewing difficulties or misalignment), they should have their teeth checked
and possibly floated (filed down) by your veterinarian. An equines teeth
continue to grow throughout their lives (actually the teeth emerge from
the gum continuously, but the teeth themselves finish growing upon reaching
adulthood). The teeth sometimes need help by having the rough edges filed
down as hooks and waves can develop and inhibit the ability for the donkey
to properly masticate his feed.
General
Since donkeys enjoy rolling, you can provide them with a bare area or
a sand heap. Work a donkey only after it is three years old..

DONKEY DISEASES AND PREVENTIVE MEDICINE
|
| |
The
most common diseases donkeys suffer from are:
Colic
This refers to bulge pain or abdominal pain. This is basically an illness
of the stomach and can occur at anytime. The most common symptoms of this
disease are- sweating, restlessness, lying down, kicking, rolling or assuming
a dog sitting position. It may be caused due to sudden change in the feed
or spoiled feed, worm infestation or sand impaction. This is an emergency
situation. The donkey should be kept warm till a vet reaches for treatment.
Colic is a major cause of illness and often death in donkeys. It is a condition
that owners and managers would do anything to prevent. Two recent studies
present evidence that in many ways they can! Detailed data was collected
on management of donkeys and factors including age, sex, size of farm, stabling
conditions, history of changes in housing, diet, history of changes in feed,
dental care, parasite control, vaccination programs, performance level,
history of changes in activity level, history of recent transport, previous
colic history, method of diagnosis, treatment and outcome. The researchers
found that a recent change of diet, stabling conditions or level of activity
could be associated with a donkey developing colic. A significant finding
was that donkeys with a history of colic or abdominal surgery were more
likely to suffer another occurrence of colic.
Large colon impaction is an important cause of colic in donkeys and is due
to feed material blocking up part of the large intestine. Research has showed
that in more than 50% of the cases there was an increase in stall confinement
within the 2 weeks prior to the development of large colon impaction. Stall
confinement could be linked to large colon impaction because of a reduction
in water intake and changes in feeding patterns. It appears that changes
in feed type together with adequate exercise may be important in maintaining
normal function of the large intestine in donkeys. This study shows that
care should be taken to ensure a gradual change in feed when donkeys are
confined to the stall and careful observation of donkeys should be made
under these conditions. Sarcoids
What is a sarcoid?
A sarcoid is a tumour involving connective tissue (ie. muscle, sub-cutaneous
tissue, etc.). A tumour which may appear outwardly similar is the Lymphoma
(cutaneous lymphosarcoma), which involves the Lymphatic system (glandular
system). Both these tumours are distinct from epithelial tumours (carcinomas
and melanomas). The sarcoid begins as a small wart-like growth, but may
progress, through stages of rapid growth, to be the size of a tennis ball.
Generally being dry scaly masses that may ulcerate and bleed, the main problems
with a true sarcoid are those of secondary infection and physical interference
e.g. with tack. The key difference between sarcoids and lymphomas is that
sarcoids are benign, lymphomas are malignant. Sarcoids exist in several
forms, (see below for details). What causes Sarcoids? Sarcoids are believed
to be caused by a virus. It has also been shown that Sarcoids occur more
often in the older donkeys and on sites of previous trauma. Sarcoid growth
appears mostly in spring and early summer; obviously there are many factors
that could precipitate this: dietary change, increased ultraviolet light,
fly strike, changing routine / stress levels to name but a few. Are there
different types of Sarcoid? Yes, sarcoids can be split into several types
which are mentioned below. Verrucous Sarcoids Typically these are dry golf
ball size lumps, though size may vary considerably. They most often occur
on the head, chest, shoulder and under-leg. As they normally lack hair,
they are not difficult to spot.tennis ball. Generally being dry scaly masses

Yes, sarcoids can be split into several types which are mentioned below.
Verrucous Sarcoids
Typically these are dry golf ball size lumps, though size may vary considerably.
They most often occur on the head, chest, shoulder and under-leg. As they
normally lack hair, they are not difficult to spot.
Fibro Blastic Sarcoids
If a verrucous sarcoid grows and splits or is otherwise physically damaged
then it may progress to this type. This is the type that tends to cause
more problems as it grows and bleeds; some have been known to reach the
size of a small football. Ulceration, fly-strike and secondary infection
can all be issues to be tackled. Growth rates do vary with these sarcoids
sometimes lying dormant for several years.
Occult Sarcoids
These are a flat form of sarcoid which again may become the fibroblastic
type if damaged.
Non Sarcoids
As previously mentioned, sarcoids can be confused with other growths. Identification
is important since many of the other growths are malignant and could therefore
spread internally. Biopsy by an expert is the most accurate form of diagnosis,
but this has its drawbacks (see under “Treatments”).
What treatment is available?
Various types of treatment are available :
Traditional Surgery
Physical removal of the tumour has been the normal practice. However there
are multiple drawbacks to this technique:
1) A high percentage of cases recur within several years.
2) Growth can be accelerated by the physical trauma of the surgery.
3) Possibility of “seeding” the tumour elsewhere by cell debris especially
if the diagnosis is incorrect and tumour is malignant.
4) Possibility of significant scarring or physical disability due to the
site of tumour operation.
Cryosurgery
This is a technique whereby the area to undergo surgery is repeatedly fast
frozen to destroy all tissue before surgical removal. This decreases the
likelihood of recurrence and seeding. However the technique is not suitable
for use near sensitive tissues such as the eyes.
Radiation Therapy
This technique is similar to that used to treat human cancer patients; the
affected area is irradiated using a localised source. The drawbacks of this
treatment are :
1) Localised side effects of radiation
2) Requirement for specially trained staff to administer treatment.
However the treatment may be particularly suitable around the eyes, where
surgery is impossible.
Immunotherapy - eg. Human B.C.G. Vaccine
This is a technique to activate the donkey’s own immune system against the
tumour cells. Two different methods can be used:
– Injection of BCG vaccine - Multiple injections are given in the tumour
over a period of some weeks.
– Introduction of sarcoid tissue - Deactivated sarcoid cells are introduced
under the skin to build the immune system over several months.
These treatment are only suitable for small tumours and do take some time
to work, however they do have the advantage of being relatively non invasive.
Chemotherapy - eg.Liverpool Cream,
Cisplatin This is a technique originally developed to treat human cancer
patients. A variety of chemical agents are being studied, the main characteristics
being:
– Application is topical or injected into tumour this minimises the systemic
effects of the toxins on the patient.
– Typically the chemical agents are toxic heavy metal compounds in an inert
carrier base.
– A dosage balance must be struck between tumour irradication and toxic
side effects. – It is beneficial where surgery is impractical or in conjunction
with surgical techniques
Other Techniques and remedies
A list of miscellaneous other treatments that can be undertaken are:
1) Laser Vapourisation - Use of a hot laser to destroy tumour tissue, typically
in conjunction with surgery.
2) Constriction - Application of a band such as a castration ring to remove
“hanging” tumours. This was also a practice for traditional wart removal.
3) Eucalyptus oil - Applied topically has apparently been of help in some
cases.
4) Thuja - Can be given orally as tablets or applied topically as an oil.
Thuja is a Chinese herbal remedy that is sometimes available from natural
health stores
5) Hyperthermia (Heat Treatment) - localised intense heating of tumour cells
using a special instrument.
6) Dermex - This is a herbal paste that can be applied topically and has
been successful on an awkward occult sarcoid. Also useful for reducing fibroblastic
size before other treatments.
7) Colloidal Silver Spray or aqueous - applied topically on a daily basis.
8) Indian Mud –Applied topically to ‘burn’ away the sarcoid.
9) Raw Honey –Applied topically, twice daily for 2 to 3 months.
10) Hilton Ditton –Herbs Used in feed as an oral immune booster. This is
quite popular and can be used along with other treatments.
11) Actimune –An oral immune booster.
12) Colostrum –Used as an oral immune booster.
Are sarcoids contagious?
Sarcoids are not considered contagious, however they may be spread by contamination
with living tumour cells. In other words any mechanism that might scrape
cells off the tumour and then place them back in another site, could lead
to the formation of a new tumour. As previously mentioned, physical trauma
to a sarcoid may accelerate tumour activity.
Hints and Tips
This is a list of suggestions that require emphasis for checking and control
of cancer in donkeys.
– Make regular inspections of any abnormal lumps and bumps on your donkey.
– If you discover an abnormality, do not do not panic. Keep a record of
any changes, as this will help your vet.
– Identification is critical. Make every effort to have a positive identification
of the tumour type before taking any decisions for treatment. Be careful
of the risk of aggravation from biopsy.
– If a sarcoid is identified consider whether or not it requires treatment.
These tumours may not trouble your donkey if left alone, yet can become
problematic after interference.
– Try to minimise any external aggravation of the tumour - A mixture of
Gammexane cream and sunblock lotion helps to reduce problems in summer without
irritating the sarcoid tissue.
– If you do not succeed at first, try again. Keep in touch with developments
in research. If your donkey does not respond to a line of treatment, consider
a different one.
Periodic Ophthalmia or Recurrent Equine Anterior Uveitis
This condition is characterised by an inflammation of the iris surrounding
the pupil. It can present itself as a one-off problem, or because of residual
after-effects within the eye an affected donkey can be prone to bouts of
recurrent inflammation and eye discomfort. In the old days, the condition
used to be termed “Moon Blindness”, as it was a superstition that the periodical
attacks were influenced by the monthly return of the moon.
However, these are many suggestions as to the cause of this condition. Uveitis
is an immune mediated disease; the inflammatory response has been associated
with a multitude of possible causes including responses to viral (such as
influenza), bacterial (such as leptospirosis) and parasitic infections (such
as onchocerciasis), and an injury to the eye can start off the initial inflammation
within the iris. Evidence suggestive of an association with leptospirosis
includes affected donkeys being more likely to have detectable leptospira
antigens on a blood test, when compared to unaffected donkeys. Experimental
infection of donkeys with leptospira was found to induce recurrent equine
anterior uveitis in infected animals.
Symptoms include inflamed conjunctiva, a tightly constricted pupil and cloudiness
of the cornea and contents
of the front part of the eye. This initial bout of inflammation may set
up a series of events that makes the eye more likely to succumb to a further
episode.
If this situation goes unrecognised or untreated it can lead to more long
term damaging problems which involve the iris becoming attached to the lens
of the eye, which it immediately overlies. This unfortunately can lead to
cataract formation and partial or complete blindness in the affected eye.
Occasionally the eye itself can deteriorate and become shrunken and sightless;
in these circumstances the eye can be removed under general anaesthesia
to remove the source of the chronic irritation. However it is contraindicated
to consider removal of the cataratous lens in a previously inflamed eye
as this can lead to a profound inflammatory reaction and a worse problem
than you started with.
The condition is not congenital or hereditary. Treatment involves anti-inflammatory
drugs such as corticosteroids, applied both to the eye and by injection,
and drugs to dilate the iris so as to reduce the chance of it becoming attached
to the lens. It has been noted that the condition has become less common
over the past few years and it has been postulated that this may coincide
with the use of a wormer containing an ivermectin, as this is known to be
effective against the Onchocerca parasite. Therefore it may be wise to ensure
that wormers containing ivermectins are part of a worming programme.
Equine Influenza
Equine influenza is a major virus disease that causes flu like symptoms
in donkeys and is from the group of viruses that causes flu in humans.
What is the incubation time?
Most donkeys exposed to the virus will show signs within a period of 1-5
days.
What are the signs of influenza?
Equine influenza appears similar to a range of other viral respiratory diseases.
Most of the viruses causing it produce rather mild signs which include a
discharge from the nose and coughing. Equine influenza produces more severe
symptoms with donkeys developing a fever and a dry hacking cough. Donkeys
become ill and are reluctant to eat or drink for several days but usually
recover in 2 to 3 weeks.
How is the influenza virus spread?
The virus can be spread easily from donkey to donkey as a result of droplets
and also from nasal discharge and from objects like infected brushes and
rugs. The disease is very contagious and there is almost 100% infection
rate in a population that has been previously unexposed to the virus.
Can it be prevented and treated?
Because it is a virus, there are no drugs that can influence the progress
of the disease. However many donkeys develop secondary infections with bacteria
which can lead to pneumonia and other problems. Good nursing care and if
necessary, antibiotics to deal with bacterial illness associated with the
disease are important parts of treatment. The most important part of dealing
with this illness is effective vaccination.
Worming
Worming of donkeys is essential. Internal parasites can cause a lot of damage
as they burrow around inside the animal. You can use paste purge wormers
every 2-4 months or a daily pelleted wormer that you can place in their
grain. An Ivermection wormer or something similar should be used. Be sure
that Ivermectin is used orally, and not injected, as there have been documented
cases of donkeys reacting severely and even dying from injected Ivermectin.
Oral Ivermectin is safe, either in paste or liquid form. It is recommended
that all wormers be rotated so an immunity to one brand will not be created
in your animal.
A more commonly used medicine is tenbendyzole, which is administered orally
in tablet form. However, before giving any medicine please consult your
vet.
Tetanus
Tetanus is a serious disease that can affect many animals including donkeys.
Tetanus spores that occur in the ground, enter the tissues of an animal
through wounds. The wound can be caused by deep penetration of a splinter
or a nail. Crushing wounds are also dangerous. The affected donkey will
become stiff in its movements, its tail is held out stiffly and its ears
are pricked. Muscle spasms may occur and the paralysis of the breathing
muscles causes death. Tetanus is difficult to cure and can be prevented
by timely vaccination.
Burns
Burns and scalds are most painful and must be attended to by a vet. The
burnt area must be covered by a clean, dry dressing such as a gauze, a clean
handkerchief or a towel and put a bandage to keep it in place. Never apply
oil, grease, flour, baking soda, spirit or tincture of iodine to the burn.
Remove any loose, charred debris from the burnt area by using gauze soaked
in warm, normal saline – 1 teaspoon of salt to 600 ml of warm boiled water.
If there is dirt or grease around the affected area, use soap and warm water
before swabbing with normal saline. For trivial burns use tannic acid, jellies,
or warm and strong tea. If the burn is caused by corrosive acid, bathe the
area with an alkaline solution which can be made by adding a teaspoon of
baking/washing soda to 600 ml of boiling water. If this is not available,
wash the area with plenty of warm water.
Dehydration To check for dehydration, pinch and lift a fold of skin
directly in front of the shoulder. The skin should immediately return back
to its normal position and if it stays in a fold for more than 3 seconds,
the donkey is dehydrated. The common causes of dehydration in a donkey are
– loosing lots of fluids because of diarrhoea or due to increased sweating
in working donkeys. To prevent dehydration, give electrolyte mix in the
donkeys water everyday. If the donkey does not take electrolyte, add a sweetener
such as molasses.
Vesicular Stomatitis
What Is Vesicular Stomatitis?
Vesicular stomatitis is a sporadic, reemerging viral disease characterized
by vesicular lesions on the tongue, oral mucosa, teats, or coronary bands
of cattle, horse, donkeys and swine. The disease also affects sheep and
goats. Many species of wild animals, including deer, bobcats, goats, raccoons,
and monkeys, are also susceptible. People who handle infected animals also
can become infected with vesicular stomatitis. Vesicular stomatitis is most
likely to occur during warm months, particularly along rivers and in valleys.
Vesicular stomatitis is a disease that must be reported to the international
animal health community when an outbreak is discovered.
How is the virus transmitted?
How vesicular stomatitis spreads is not fully known; insect vectors, mechanical
transmission, and movement of animals may be responsible. Once introduced
onto a premises, the disease apparently moves from animal to animal by contact
or exposure to saliva or fluid from ruptured blisters.
What are the clinical signs?
The incubation period for vesicular stomatitis ranges from 2 to 8 days.
Infected donkeys suffer from blister-like lesions in the mouth and on the
lips, nostrils, teats and coronary bands. When blisters break open, they
leave painful ulcers that cause donkeys to drool or froth at the mouth,
the most common clinical sign of the disease. This sign can sometimes be
confused with biting problems, dental problems or colic. Infected animals
generally suffer weight loss because they refuse to eat or drink. Mild lameness
can occur if lesions develop along the coronary bands. However, cases have
been reported where lameness is severe enough to cause sloughing of the
hoof. Vesicular stomatitis does not generally cause donkeys to die.
What is the risk to human health ?
People who handle an infected donkey can contract vesicular stomatitis if
they fail to follow proper biosafety methods. In humans, vesicular stomatitis
causes an acute influenza –like illness with symptoms such as fever, muscle
aches, headaches, and malaise. Vesicular lesions are rare in humans.
Donkey-hauling trucks etc. should be cleaned and disinfected. Drivers of
these vehicles should change contaminated clothing before returning to their
home base.
For footbaths and disinfection of facilities and equipment, phenolic- and
halogen-based disinfectants work best. Sunlight and heat also destroy the
virus quickly.
Effective disinfectants
The following list shows disinfectants found to be effective in deactivating
the vesicular stomatitis virus when used for 10 minutes.
– Disinfectant Concentration
– Chlorine bleach 0.645 percent
– Wescodyne 4 percent
– Cresylic acids 1 percent
– Roccal 1:200
– Septisol 1:50
Vaccination
Vesicular stomatitis vaccines for donkeys have been available intermittently
during years when outbreak of the disease has occurred. However, little
information is known about their efficacy in preventing infection, reducing
clinical signs associated with infection, or lessening the economic impact
of infection.
How can you treat infected animals?
Treatment for donkeys infected with vesicular stomatitis is primarily supportive,
such as the use of soft feed. Antibiotics may be required if secondary infections
develop. Infected animals recover in 1 to 2 weeks if there are no complications.
Vesicular stomatitis is diagnosed by isolating the virus from epithelium
around vesicles or from vesicular fluid. Laboratory tests using serum are
also available for detecting the virus. Producers need to differentiate
between vesicles in the mouth caused by vesicular stomatitis and vesicles
caused by photosensitization or trauma due to rough feed.
Report suspicious cases
Implementing appropriate, recommended management practices and working closely
with your veterinarian can reduce losses. Veterinarians and livestock owners
who suspect that an animal may have vesicular.
stomatitis or any other vesicular disease should immediately contact the
animal health authorities.
Strangles
“Strangles” is a term used by most lay people to describe the clinical syndrome
produced by the bacterium Streptococcus equi.
Although the symptoms of strangles vary from case to case, the classic description
includes swelling and infection of the throat region. There is usually a
fever in the beginning. The donkey may be depressed and unwilling to eat.
There is often a nasal discharge, which may be serous or mucoid initially
but quite purulent (containing pus) as the disease advances. Affected animals
usually cough. Many affected animals may resist palpation of the submandibular
and retropharyngeal area (this is between and just behind the jaw bones).
In most individuals the organism spreads to cause abscesses in the retropharyngeal
or mandibular lymph nodes.
The disease is most commonly transmitted through infective secretions. Once
the disease establishes itself on a farm, it often becomes a persistent,
recurrent problem even though there may be long periods when no resident
donkeys have clinical signs of the disease. Once the organism establishes
itself in a susceptible population, the percentage of animals affected is
generally quite high and often approaches 100%. However, mortality in most
uncomplicated cases is low. Listlessness and rapid spread of the disease
are also common. Most uncomplicated cases are confined to the upper respiratory
tract; however, involvement of the lower respiratory tract can cause pneumonia.
In some donkeys the organism localizes in the guttural pouch or paranasal
sinuses and is a constant source of purulent discharge from the nostrils.
Persistent drainage from the submandibular or pharyngeal areas occurs in
some cases. Cranial nerve dysfunction may occur in cases of retropharyngeal
abscesses affecting the recurrent laryngeal nerve. In donkeys with the most
severe form of strangles, any part of the body or viscera may be affected,
including the heart.
Streptococcus equi is quite susceptible to penicillin and it is often the
preferred treatment. Some vets believe that the use of penicillin only retards
the growth of the bacteria and makes the infection last longer or may cause
the infection to spread internally where it is much more difficult to assess
and treat.
Penicillin is not necessary if the donkey is alert and has a reasonably
good appetite. Good nursing care and minimization of stress are important
in all cases. A palatable diet and dry, comfortable surroundings should
be provided. If warranted and practical, application of hotpacks helps promote
maturation of abscesses.The name strangles comes from the effect that can
come about when the throat abscesses grow so large that they cut of the
trachea (wind pipe) and actually strangle the donkey.
Severely affected donkeys may require intensive supportive therapy, including
intravenous fluids, feeding by nasogastric tube and tracheotomy (cutting
a breathing hole in the wind pipe). The use of penicillin is indicated if
the temperature remains high for a long period, the donkey is severely depressed
and lethargic, and the pharyngeal and retropharyngeal areas are severely
affected. The decision to administer penicillin should be closely evaluated
if young animals or many animals on a farm are affected. In some cases the
stress of rounding up and restraining affected animals to administer penicillin
outweighs the benefits of therapy. Other antibiotics should only be used
if indicated by culture and sensitivity tests.
If recognized early, an outbreak of strangles can be contained by isolation
of affected donkeys and strict hygiene by handlers. Although vaccines have
been developed, they are not nearly as effective as other types of vaccines.
The donkey owner should take the advice of the veterinarian about vaccination.
He has the right knowledge and experience of the disease and the vaccination
to be taken. The vaccine may be more effective in one area than in another.
To guard the donkeys against strangles, they must be vaccinated.
Glanders
Nature of the disease
Glanders is a serious bacterial disease, principally of equids. It is an
important zoonosis i.e. it can be transferred from donkeys to humans.
Clinical signs
The disease may be acute, chronic or latent. It is usually acute in donkeys
and mules. The signs of the disease are the following:
Acute form
– high fever
– coughing
– thick nasal discharge
– rapidly spreading, deep ulceration of the nasal mucosa
– swollen and painful sub-maxillary lymph nodes
– death in 1-2 weeks
Chronic form
Onset is insidious, but slowly progressive and may lead to death. The signs
include:
– malaise coughing, and intermittent fever
– chronic purulent nasal discharge
– ulceration of the nasal mucosa
– chronic enlargement and induration of lymphatics and lymph nodes
– cutaneous lesions (‘ farcy’) — skin nodules, most common on the legs,
that rupture and ulcerate
– painful oedema of the legs and swelling of joints
Latent form
Lesions only occur in the lungs. There are a few clinical signs:
– occasional laboured breathing
– nasal discharge Indications of the disease
The following signs of strangles may be looked for during examination of
the donkey:
– catarrhal bronchopneumonia with enlargement of bronchial lymph nodes (especially
in acute form)
– nasal cavity, pharynx, larynx and trachea with nodules, ulcers and stellate
scars
– lungs with miliary, firm, rounded, encapsulated grey nodules resembling
tubercles
– nodules may also be seen in the liver spleen and kidneys
– cutaneous lesions
– swollen lymphatics with focal abscesses in lymph nodes
Transmission of Infection
The infection is transmitted in the following manner:-
– Equids generally acquire infection by ingestion. Environmental contamination
(especially through food and water troughs and other utensils) by nasal
discharge and pus from skin ulcers is a major source of spread.
– Animals can also become infected via contamination of skin abrasions e.g.
through dirty grooming utensils or harness.
– The organism can survive in the environment for up to two months in sheltered
conditions. Latently infected donkeys can continue to spread the disease.
Human infection results from contact with the discharge of infected animal
caused usually by contamination of skin abrasions or cuts. Carnivores become
infected by eating infected carcasses.
Risk of introduction
Glanders could be introduced through the import of infected donkeys or contaminated
fodder or equipment. While latent infections can occur, the generally severe
clinical picture, together with declining incidence and distribution of
this disease, suggest that the risk of introduction is probably low. The
mallein test is a reliable, allergic diagnostic test that can be used to
screen the animal. This test is performed by injecting 1 ml of the antigen
(which is a purified protein ) into the lower eye lid of the donkey. A positive
reaction gives extensive oedemia of the eye lid, congestion of the conjunctiva
and muco purulent secretion from the eye.
Control / vaccines
No attempt should be made to treat animals as these can become sub-clinical
carriers. Affected animals should be destroyed and carcases burned or buried.
Premises should be thoroughly cleaned and disinfected. Animals in contact
should be quarantined and tested
Equine Viral Abortion
Nature of the disease
Equine viral abortion is due to infection with equine herpes virus type
1 (EHV1) which causes rhinopneumonitis, abortion, neonatal mortality and
occasionally encephalomyelitis in horses and donkeys.
Clinical signs
Abortions and rhinopneumonitis appear to be caused by slightly different
strains of EHV1.
The rhinopneumonitis form of EHV1 is usually seen as an outbreak of upper
respiratory disease (‘ colds’) in young donkeys during autumn or winter.
Affected donkeys have:
– a sudden fever lasting 2-5 days
– intermittent serous nasal discharge
– congestion of the nasal mucosa and conjunctivae
– inappetence (loss of appetite)
– slight enlargement of the submaxillary lymph nodes,
– occasionally oedema of the legs
Recovery usually occurs within a week. Occasionally the nasal discharge
becomes mucopurulent and continues for 1-3 weeks accompanied by a cough.
Adult donkeys seldom show clinical signs, although they may undergo sub-clinical
infection.
Abortions due to EHV1 usually occur in the last 4 months of gestation, but
may occur as early as the fourth month. Infection usually occurs 1– 4 months
prior to abortion and infected mares show no signs of respiratory or other
illness. There are usually no complications after the abortion. The foetus
is expelled dead, with the foetal membranes intact. Occasionally, when infected
late in gestation, infected foals are either stillborn or die within a few
days of birth.
The conception rate, 30 days after abortion, is high. Abortion occurs most
commonly during the first pregnancy. Having once aborted, breeding is usually
normal in subsequent years, and abortions only rarely occur again. Encephalomyelitis
due to EHV1 is rare:
Indications of the disease
In cases of rhinopneumonitis there is
– inflammation of the upper respiratory tract
– an initial leucopaenia that is replaced later by a leucocytosis
– pulmonary oedema and fibrinous infiltration of interstitial tissues
Foetuses aborted before 6 months show widespread necrosis with intranuclear
inclusion bodies, especially in the liver and lungs. Those aborted after
6 months show:
– jaundice
– petechiation of mucous membranes
– enlargement of the spleen
– white to cream-coloured necrotic foci in the liver
– accumulation of fluid in the pleural cavity
In stillborn foals, or those dying soon after birth the main gross lesions
are enlarged, lungs are plum to purple coloured that are oedematous and
only partly aerated. There is fluid and froth in the bronchi, and subepicardial
and subendocardial haemorrhages.
Transmission
EHV1 infection spreads mainly by the respiratory route, although infection
by ingestion and transmission by fomites is also thought to occur. Aborted
foetuses contain large amounts of virus and may be responsible for the introduction
of the abortogenic strain to previously uninfected premises.
Previously infected adult donkeys may undergo subsequent subclinical infection,
although it is unclear whether this is due to re-infection or re-activation
of a latent infection. It is not known whether a latent carrier state occurs
with EHV1, although this is common with other herpes viruses.
Control / vaccines
Prevention of disease due to EHV1 is mainly by the use of measures to minimise
the risk of introducing the virus, in combination with the use of vaccines,
where available.
Saddle Sores
These are caused due to lack of any type of saddle or protection for the
donkey's back from the load. These may also be caused due to poor fitting
saddles which cause excessive pressure and/ or frictional rub. The sign
of sores is hair that are rubbed of and broken skin on the side of the withers
or under the girth that often leaves raw bleeding sores that vary in size
and are slow to heal.
Treatment
Rest the donkey from work and remove the saddle and the girth. Check the
saddle and the girth in respect to the size of the donkey and adjust the
method of loading to rectify the problem. If rest is not possible, sores
on the withers or the back may be protected from further rubbing by surrounding
the affected area with a dough shape gauze pad or dressing. Apply zinc cream
to the sores twice a day until the signs of drying and healing appear. For
advanced wounds, clean the sore with peroxide, dry with clean gauze, dust
with antibiotic powder or paint with gentian violet or use an aerosol spray
containing antibiotic and gentian violet. Dermobion, a cream containing
antibiotic and anti-inflammatory active ingredients, is also useful where
the wounds are exposed to self trauma. Quidding
This is a condition when the donkey will take food into the mouth, chew
it and expel it on the floor. It is usually a result of improper chewing
due to pain in the mouth or restricted movements of the jaws. This is usually
due to teeth abnormalities, either because they are loose or they have worn
down irregularly. Regular examination of the mouth is recommended and rasping
of the cheek teeth at least once a year should be carried out in donkeys
over five years of age. By the method of teeth rasping, the uneven teeth
are filed down by using an instrument called a rasp. During this process,
the donkey’s nose can be held with a twitch. This twitch can be of two types,
either it can be a metal pincer or it can be a short pole with a circle
of rope at the end that can be twisted to hold a donkey’s muzzle very tightly.
This helps to keep the donkey’s head steady so that the rasping can be attended
to as quickly as possible. The minor pain of the twitch on the muzzle leads
to the release of the natural pain– relieving chemicals which also makes
the donkey calm and easier to control.
Rabies
Rabies is a viral infection of mammals transmitted by the saliva of a rabid
animal. In most of the cases, the early signs are drooling of saliva, spastic
lip movement, hyperexcitability leading to depression and anorexia. Rare
cases develop with biting, kicking and self mutilation as overt signs. Paralysis
develops primarily affecting the ability to swallow, then spreads to the
hind quarters, with collapse or death in 2 – 7 days after the initial signs.
Treatment
Rabies is invariably fatal. Isolate the donkey from other animals and people.
In confirmed cases, treatment is not advised and euthanasia is recommended.
COPD
Chronic Obstructive Pulmonary Disease is also known as Broken Wind , Heaves,
dust allergy or Emphysema. This disease is similar to asthma in humans and
is usually caused by an allergy, usually to fungal spores in the dust in
hay or straw. The temperature of the affected donkeys is usually normal
although an episode may occur following any respiratory infection. The breathing
is very laboured and wheezing can be heard even without the aid of a stethoscope.
Affected donkeys may cough. Their condition is improved by stabling them
and by reducing their exposure to dust. If they need to be housed then the
bedding must be changed from straw to wood shavings or paper as these are
less dusty. Hay should be fed by soaking it overnight to keep the dust down. |
FOOT CARE
|

All donkey owners must ensure that their donkeys get proper foot care. The
feet must be examined by a farrier, regularly and frequently. A period of
6 – 10 weeks between the inspections is recommended. heel quarter toel
Trimming the donkey’s foot
It is necessary to trim a donkey’s hoof enable the donkey to move with
a sound and free action and to ensure the aesthetic shape to the foot and
lower limb so that there is no undue stress or pain on the hoof capsule,
joints, ligaments and tendons of the lower leg. The theoretical mainstay
of achieving this has been the adoption of the principles of maintaining
the ideal “hoof pastern axis”(HPA) and "mediolateral hoof balance" (MLHB)
1 Trimming the hoof pastern axis
The HPA is given by the line BC in the diagram below. Its reference points
are:
i) The proximal centre of the 3 rd metacarpal (cannon) bone
ii) The distal centre of the 3 rd metacarpal (cannon) bone
iii) The centre of the distal phalanx.
According to this principle the cannon bone should be perpendicular to the
ground and the line BC should intersect the three lower joints so that the
proximal, middle and distal phalanges represent a bony column in a straight
line with no deviations. This line should make an angle of approximately
55 – 60 degrees and should be parallel to the dorsal wall of the hoof. This
cannot be too prescriptive, however, as the age of the donkey and its previous
history will dictate what should be achieved.
Using these guidelines, the three possible alignments of the HPA are the
following:
i) The theoretical ideal is aesthetically pleasing and is thought to create
the optimal pressure on the hoof capsule, joints, ligaments and tendons
of the lower leg.
ii) A broken back HPA occurs when the heels are too low and / or the toe
has been allowed to grow excessively long. Undue strain is then put on the
foot, which, in turn, may encourage abnormal wear of the hoof capsule.
iii) Broken forward HPA occurs when the heels are too high and the toe is
too short . Excess stress is put on the lower limb joints, and concussion
to the joints is believed to be increased.
NOTE: The prominent band of soft tissue and hair that often bulges
above the coronary band are the distracting
features of the donkeys foot. They can lead to the misconception of a broken
forward HPA as during the visual assessment, they have the effect of lowering
the external angle of the BC. Hence this distracting feature of the donkey’s
foot should be ignored during visual assessment.
2 Trimming and medio lateral hoof balance
The medio lateral hoof balance indicates that an imaginary line bisecting
the lower limb should be perpendicular to the line drawn across the heels.
The aim of this aspect of trimming is that, in the ideal and non – disfigured
limb, the hoof hits the ground squarely so that comfortable weight transfer
from the hoof capsule to the bony column is achieved.
But the hoof capsule grows and wears down according to the natural weight
distribution and the favour of a particular footfall by the donkey. Hence
in time it is unlikely that the bearing border of the hoof capsule will
be perfectly perpendicular to the long axis of the cannon bone. This needs
to be corrected by trimming.
3 Trimming the donkeys foot
It is important to have made a full visual assessment of the donkeys feet
before any attempt is made to wield a hoof knife. In general terms, if the
hoof appears very upright with strong heels and perhaps a broken forward
HPA, then there is likely to be a scope for removing more horn from the
heel area. Should the toe be long and the heels low, perhaps with a broken
back HPA, then it will be important to retain as much of the heel tissue
as possible and concentrate on shortening the toe. If major changes in the
shape of the hoof are required then, for the donkey’s comfort, it is worth
considering effecting the changes in a series of gradual changes rather
than all at once.
How to trim the hoof
Trimming the sole
In order that the distal rim of the hoof wall actually bears the weight
of the animal, then the solear material should be trimmed first. This is
best taken back in incremental amounts so that the solear surface is concave
and all loose or dead tissue is removed, especially near the point of the
frog. It is often difficult to judge how far back
to trim and care must be taken not to be over zealous and penetrate the
sole. Most trained farriers trim back till the sole yields very slightly
to “thumb pressure” applied between the dorsal and point of frog. Soles
should be made to bear very little weight. Soles that bear large amounts
of weight, especially when thinned, can lead to bruising and concussive
laminitis.
Trimming the wall
The wall is trimmed paying attention to medio lateral balance and how much
heel needs to be retained to maintain, as closely as possible, the ideal
HPA.
Trimming the frog
The grooves of the frog are potential sites for harbouring dirt, stones
and infections. The rubbery horn of the frog will often grow over these
cavities and create a trap. These should be completely opened out during
trimming so that they do not clog.
Trimming of the bars
In practical terms, if the donkey is doing road work, then the bars should
be retained and should be of the same height as the heel hoof tissue. However
if the donkey is on soft ground or deep litter then there is an advantage
to trimming the bars back to the sole level so that they do not become,
like the frog, a potential harbour for muck, stones and infection.
‘Dressing’ the hoof wall
Once the foot is trimmed and cleaned, it is common practice to rasp the
distal bearing surface. While doing so, an effort should be made to avoid
excessive rasping in an attempt to cosmetically improve the appearance of
the HPA. This is because excessive rasping is likely to remove the outer
layers of the hoof wall. This could increase the propensity for uncontrolled
moisture changes across the wall which may lead to cracking.
Seedy Toe
There is a considerable debate as to the causes of this condition. It is
not clear whether it is an aerobic or anaerobic. The characteristic lesion
shows areas of gray, crumbly horn which, in long standing cases , are associated
with large, hollow often triangular cavities within the hoof wall with the
apex of the cavity towards the coronary band. The hoof ball may also bulge
in the affected area.
Various fungicidal and bacterial treatments have been advocated for this
condition but the common feature of the treatment is that the affected horn
must be completely resected. Because of the degeneration of the wall, this
is a painless operation. All powdery gray material must be removed on resection,
otherwise recurrent pockets of persistence are found on subsequent trimmings.
Sometimes the work required to do this is minimal, at other times a complete
hoof wall resection may be necessary. The use of fillers is not recommended
in case any residual infection is trapped in place. Aftercare is not usually
very taxing provided there are no complications. The patient should be kept
in a clean dry environment and resected lesions cleaned out regularly. In
these cases only the sole is allowed to bear weight and it often responds
by becoming thickened while the new hoof walls grows down. The only animals
that cannot be treated are laminitics that may have insufficient sole to
carry weight.
Laminitis
Laminitis is a complex systematic disturbance that manifests itself, at
the level of the foot, by bounding “digital” pulses, changes in the blood
flow and degeneration of the laminar tissue that may result in “rotation”
and/or “sinking” of the pedal bone within the hoof capsule. Any combination
of feet may be affected at one time. It is usually preventable subsequently
by changing management regimes and improving foot trimming and awareness
of the owner.
The main causes of laminitis is overlong feet, trauma on hard ground, incorrect
diet, concurrent diseases, stress and pituitary tumours. Laminitis is a
serious condition needing immediate veterinary attention. The donkey should
not be made to walk but should be put in a stable with a thick shaving or
a paper bed. If the predisposing cause of laminitis is known, it should
be removed (e.g. move the donkey from succulent pastures) or treated (e.g.
respiratory infection, metritis etc.)
Foot bandages , well padded with thick cotton wool pads over the whole of
the solar surface, applied to clean, dry foot, often give pain relief while
waiting for the veterinarian to arrive. Animals which are “rooted to the
ground” and unable to walk should have only roughage and water brought to
them.
Owners should know how to feel for digital pulses and palpate the coronary
bands for ditches and depressions, in order to recognize the first signs
of laminitis. Chronic laminitic feet may show diverging laminitic rings
in the hoof wall, but these are not very obvious in a donkey. Moreover in
donkeys, sole support is the best. The feet are normally X- rayed with the
markers on the hoof wall to assess changes in the position of the pedal
bone and any loss of bone density. It is imperative that further attacks
are prevented so that the pedal bone is not permanently and irretrievably
damaged.
After a laminitic attack the horn growth is usually rapid. Therefore the
feet should be trimmed every 3- 4 weeks. However trimming soles of laminitis
can prove problematic due to increased prolapse (moving out of place), pressure
and lack of concavity on the laminitic sole. Achieving concavity of the
sole is not, therefore, always possible and ‘thumb pressure’ may also be
used with care. Long standing cases can have associated deep seated solar
abscesses with loss of pedal bone and chronic uncontrollable pain. This
inevitably leads to a humane destruction of the animal.
White line separation In the absence of other conditions such as
laminitis, the usual cause for white line separation is mechanical. If the
hooves are neglected and allowed to grow excessively long then the excess
leverage at the toe can mean that the white line separates and parts of
the wall breaks away. This leaves a cavity in the white line allowing the
entry of dust, gravel and potential infective agents. This can lead to the
cavity progressing further up the foot. White line separations are also
seen at the quarters and the heels. The treatment for this lies in the resection
of infected areas while restoring normal foot shape and balance.
Thrush
Thrush is an infection of the horn which results in the separation of the
frog and horny sole from the underlying tissue. There is a foul smelling
discharge in the frog grooves and along any other tracks that are undermining
the hoof tissue. Many types of bacteria and fungi have been isolated from
these infections. Thrush is a result of poor management, lack of foot care
and wet conditions underfoot. It can be very severe and very painful if
live tissues are penetrated. Long standing cases can lead to time consuming
and expensive treatment by the vet and farrier. All dead tissues have to
be removed and the remainder kept clean and dry.
Abscessation
Foot abscesses are a common cause of acute and severe lameness in the donkey.
Any penetration of the sole by a foreign object , or penetration of the
white line, can lead to a deep seated abscess. A separated white line is
more prone to penetration and therefore must be avoided. Infections of the
white line may tract up the wall of the foot and burst out at the coronary
band.
Veterinary advice should therefore be sought if a foot abscess is suspected
and especially for a lame donkey. The pus tract will require radical cleaning
and all infected areas must be drained. Tetanus antitoxin and antibiotic
therapy along with foot cleaning and dressing will be necessary.
Sand Crack
It affects the hoof wall. It is a crack that can extend down from the coronary
band to the base of the hoof. It is usually a consequence of an injury to
the coronary band or caused by excessive dryness of the hoof wall. This
overdryness is often due to over enthusiastic rasping. The donkey may become
lame and evidence of infection is rarely found under the crack.
Feet Care
Inspect the donkey’s feet regularly, check for stones and trim their shoes
after every two months. Moreover the donkey’s feet should be soaked regularly.
The following are important tips for foot soaking:
• Make sure the water is not hot. Start out with water that is only slightly
above body temperature and with each soaking increase the temperature just
slightly until it reaches a temperature you find comfortably warm on the
fragile skin inside your wrist.
• Use a rubber bucket, pail or feed bowl. A thick rubber pail holds the
temperature longer than plastic or metal.
• The height of the soaking pail should allow the water to cover the fetlock.
• Put a folded towel in the bottom of the pail to cushion the foot.
• Pick up the foot that you are going to soak and slip the pail under it
as you put the foot down. Then go around to the other side of the animal
and pick the other foot up and hold it 3 or 4 inches off the ground to discourage
the animal from taking her soaking foot out of the pail.
• Hang a haybag or feed pan at chest height right in front of the animal
and feed her everytime she gets her foot soaked. If they eat their treats
fast add it one piece at a time to make it last longer.
• On the foot you are holding that is not being soaked, rub a circle with
your thumb just above the coronetband in the front center of the pastern.
This is a relax-reflex spot and magically mesmerizes them.
• After the foot has soaked for the alloted time, remove it from the pail
and wrap a warm-from-the-clothes-dryer fluffy towel around it until the
towel cools.
• Epsom salts can be irritating to the skin so use a warm drippy-wet washcloth
to rinse the salts off the foot afterwards and towel dry it.
• Choose an area for your soak that is as flat as you can find to avoid
the donkey thinking she needs to scramble to keep from falling over when
she’s standing on 3 legs.
Hoof Care
Clean out the hooves regularly. Remember donkey hooves are very elastic
and do not wear down like those of other equines. If left untrimmed they
grow to astounding proportions and such neglect can cause an animal to be
permanently crippled. Ideally hooves should be trimmed every four to eight
weeks depending on the age and speed of growth. The hooves of foals generally
grow faster than those of adult donkeys. Keep feet short and neat. |
ALTERNATIVE MEDICINES FOR WORKING DONKEYS
|
| |
In
developing countries, like India, most of the donkey owners cannot afford
veterinary fees and expensive drugs. Donkeys are frequently sent to the
slaughter house because of the cost of veterinary service and treatment.
Animals often have to work in conditions when they are not well. Often local
remedies are tried which might work or sometimes make the donkey even worse.
This is the reason why the efficacy of local remedies and herbs must be
tested. The use of honey for curing burns when applied directly over the
wound has shown good results. Thermal therapy is useful to cure muscle and
tendon problems. Active charcoal is used to cure diarrhoea in foals. Sugardine
is very popular in feet infections. Garlic and other herbs have proved to
have antibacterial properties. Ethnoveterinary as opposed to modern drugs,
seeks natural, ecological and economically viable alternatives that may
be readily used by the donkey owner.
Honey as a dressing for wounds
Wounds are the main health problems in working donkeys. The most common
place to find wounds are withers, thorax, back and limbs. The common causes
are the use of harness made with inappropriate materials, bad design of
carts and heavy loads.
Honey has been used for dressing wounds from time immemorial. Honey helps
in curing wounds because its thickness provides a protective barrier. Hydrogen
peroxide is released from the honey slowly which is a well known bactericide.
Amino acids with vitamin C speed the growth of healthy tissue.
Procedure
Clean the wound . Use surgical soap and additionally some iodine solution
to clean it well. Then apply a good dressing of honey. Some experts recommend
to not put honey directly into the wound, but to put it on a piece of gauze
first and then cover the wound with it. If there is a cavity or a big abscess,
it is widely recommended to first debride the abscess and then fill the
hole or the cavity with honey and finally cover it with the gauze. This
procedure has to be done everyday i.e. every 24 hours. But some people may
prefer to do it twice or even three times in the day. It is recommended
to do it once in the day if the wound does not get dirty with urine or faeces.
If the wound does get dirty, then this procedure may be used twice or three
times in a day.
Although honey is useful to cure all types of wounds, it is especially effective
with cavities. This is because the honey is able to stay longer on the tissue
and promote the healthy granulation tissue.
Thermal Therapy
Thermal medicine has been used in human medicine showing good results. This
consists of the application of heat or cold to the site of the injury.
This therapy is now recommended by veterinarians for the treatment of muscle–
skeletal injuries. This therapy can alleviate both chronic or acute illness.
Application of cold therapy to an injury or wound helps in decreasing swellings,
pain, oedemia, blood flow and the activity of inflammatory mediators at
the sight of the injury within the first 24 – 48 hours. Cold therapy causes
vasoconstriction ( constriction in blood vessels) that can reduce oedemia
and haemorrhages. It is also believed to be an analgesic after 10 or 15
minutes apparently because it reduces the conduction of the nerves. The
term analgesic refers to any drug that causes a temporary loss of the sense
of pain without losing consciousness.
Heat therapy has been recommended after 72 hours of injury. This reduces
pain, increases tissue extensibility and local blood flow. All these events
allow to have more metabolic activity which will promote a quicker recovery.
Heat is used to reduce the swelling caused by blood or serum. Optimal temperatures
for heat therapy are 40 to 45 degrees Celsius
Procedure
Cold therapy – it has been proved that the best way to get the tissue temperature
between 15 to 19 degrees, is by using icy water. This can be prepared using
4 kilos of ice in 15 litres of water. The leg of the donkey can be soaked
in the bucket for 30 minutes. Within the first 10 minutes the tissues will
reach the optimal temperature for recovery. However in the case of a face
injury cool packs or even ice may be used. Cold therapy should not exceed
30 minutes. This is because if the treatment is applied too long there is
a possibility of it producing reflex vasodilation (dilation in the blood
vessels after cold treatment is removed.)
Heat therapy -
this therapy is also best done by using water. The water at 40 to 45 degrees
Celsius can be taken in a bucket to soak the injured part for 10 to 20 minutes.
Active Charcoal
Charcoal has the effect of binding gases and toxins through absorption.
It is very useful in treatment of diarrhoea in foals.
Procedure
For foals, take 10 gm of charcoal and mix it with 1 ounce of water. Administer
it to the foal through the mouth every 12 hours. For adult donkeys use 20
gm of charcoal mixed with about 2 ounces of water.
Sugardine
Sugardine is a mixture of sugar with Betadine. Betadine is one of the most
effective antiseptics available It is very effective against bacteria, yeast
and viruses. The mix of Betadine with sugar seems to make the structures
of the feet harder and also keeps them clean. Sugardine is useful in subsolar
abscesses, thrush, or any other foot condition that involves infected tissues.
Procedure
Take a standard size glass and put betadine in it. Betadine is commonly
available in India at most of the chemist shops. Now start adding common
sugar to it till a thick paste is formed. The surface that has to be cured
has to be perfectly clean before the mix is applied on it. Once the sugardine
is applied on the recommended area, cover it with gauze and then bandage
it.
Garlic as an anthelminitic
Anthelminitics are substances that are given to expel parasitic worms. Donkeys
are vulnerable to an array of diseases of biological origin and parasitism
is the common entity leading to ill health, suffering and early demise.
Inspite of this, they are not given anthelmintic treatment due to ignorance
on the part of the owners.
Most of the suffering caused to the donkey is because of parasitism, as
under this condition the donkeys are not even able to take full advantage
of the little feed given to them. Hence their body condition is generally
low and with improper harnessing this may result in sores. Modern anthelmintics
are not widely available and due to their expense, they are used infrequently
used in the preventive care of the donkey.
For many years the medicinal properties of garlic and other herbs have been
advocated by herbalists. But only recently the use of garlic as an anthelminitic
in donkeys has been promoted. Ground garlic may be a cost effective alternative
to commercial products for parasites. Local application of aqueous extract
of garlic cream 10 % V/W completely cures the lesions of ring worms, the
average time required being 13.08 +/- 0.79 days. Garlic has shown a good
antibacterial activity, lipid (fatty substances) lowering effect, anti platelet
activity (platelets or thrombocytes reduce loss of blood from injured vessels
by the formation of a white clot ) and anti carcinogenic effects. Carcinogins
are substances that give rise to cancer.
In a recent study on garlic as anthelminitic in donkeys, boiled garlic was
found to be totally ineffective in reducing the herd egg count of strongyle
spp. It is believed that one of the reasons for this is that a compound
of garlic called Allicin is destroyed when the garlic is boiled.
Turmeric Powder
Turmeric powder is known for its antiseptic properties. It may be sprinkled
directly if the wound is wet with blood. However, if the wound is dry, then
a turmeric paste needs to be made. This can be done by mixing turmeric powder
with cooking oil i.e cooking oil, mustard oil etc. This paste can then be
applied on the wound.
Neem Oil
Neem oil is a popular fly repellant that is used widely in India. It may
be sprayed on the donkeys to help keep the flies away.
Anona Paste
Anona plants are found mostly in south India. The leaves of this plant are
ground and the paste formed may be applied to maggot wounds. . |
DONKEY BEHAVIOUR
|
| |
Donkeys are
complex creatures, capable of many moods. They can be friendly, affectionate,
independent, patient, and even sad, and there is no questioning their
intelligence. But when a donkey would rather not do something, it can
be the laziest and most stubborn creature in the world.
Donkeys are hardy animals and are remarkably resistant to disease. Hoof
care is essential to the well being of these animals. When kept on soft
ground the hooves grow rapidly and soon become extra long. This puts great
pressure on the pasterns as the animals’ weight is no longer directly
over its hooves. A farrier or veterinarian should be consulted for advice.
In the wild, donkeys travel in herds of up to 100 animals, usually led
by a male. Although they are gregarious by nature, the herd breaks up
at foaling time. Donkeys are most active in the evening, but also move
about during the day and at night. When threatened, their defense is to
run or bite.
Donkeys communicate with their human owners and with other donkeys by
“braying”. Every donkey has his or her own style of braying with some
sounding quite comical. They range from barely being audible to a loud
thunderous bray. Donkeys develop schedules and if you are late in feeding,
you will hear about it! Jacks pastured apart from their jennets will call
to them several times a day. On the whole, donkeys are very quiet animals.
As in the case of other animals, the most important donkey behaviours
are drinking, eating, urinating, defecating, resting , grooming and mating.
Abnormality in any one of these or their absence are very important behavioural
signs. In addition there are many other aspects of donkey behaviour that
help in understanding donkeys better:
• Loud or persistent braying indicates that the donkey is stressed because
of fear or loss of contact with other donkeys.
• Lethargy and lack of interest in anything, and standing away from other
donkeys, may signal ill health.
• Limping while walking or trotting indicates leg or hoof problems.
• Excessive rolling on the ground and / or repeated rubbing may indicate
skin parasites and digestive problems such as colic i.e excessive gas
in the digestive system.
• Eating things other than grass, such as soil and bushes may indicate
a nutritional deficiency or boredom.
• Grooming itself or other donkeys, allowing itself to be groomed and
investigating new things are all signs of well being or good health.
• Aggressiveness is common behaviour in male donkeys although it is something
to be prevented at all costs. Based on the appreciation of donkey behaviour,
it is possible to list some general guidelines for handling donkeys:
• Always speak to the donkey in a gentle tone as you approach it and use
its name if you know it.
• Always try to approach from the front so that the donkey can see you
and always lead it on the left side. The left side is the conventional
side for controlling equids and is used worldwide by experienced handlers.
• If you need to touch any part of the body, start by checking the neck
and then slide your hand gently to the area you wish to touch e.g. a hoof,
whilst at the same time reassuring the donkey by speaking to it softly.
Avoid grabbing at the legs and the hooves without warning the animal first
by prior touching the body.
• Most donkeys like the base of their ears to be scratched, but they do
not like their ears to be pulled. Reproduction and growth
The gestation period for donkeys is approximately 12 months. There is
usually just one foal, which is able to stand up within minutes after
birth. The foal remains with its mother for about five months. Females
achieve puberty at one year. Some important reproductory facts about donkeys
