Feeding elderly donkeys

• Carry out donkey specific body condition scoring regularly. It is important to use your hands because the thick coat can hide any loss of condition.
• A feed test is always a good idea; give the donkey some feed and watch to make sure that it does have an appetite, can chew and does swallow the food. Watch carefully for sham eating and check for quidding.

Sham eating is giving the impression of prehension, mastication and swallowing whilst actually ingesting very little

Quidding is the dropping of balls of well-chewed food into the feed trough, bucket or on the f loor instead of swallowing it.

• If in doubt, a check of the fibre length in a faeces sample will give a very good indication of the function of the digestive tract (just under 2mm is normal, over 3.6mm likely indications limited dental function).
• Regular checks of the dental function is essential and either a vet or a dental technician should carry out checks every 6 months and appropriate treatment where necessary.
• Donkeys have specific requirements, which are often very different to those of horses and ponies, and it is important to be aware of these. See our factsheet: Donkey dental care.

Donkeys have evolved to eat fibrous plant materials in small quantities throughout the day. This is known as trickle feeding and helps to keep the donkey’s digestive system healthy and to keep the donkey occupied. When donkeys have poor teeth and are finding long fibres difficult to chew, it is important to provide them with an alternative source of fibre. There are a number of hay replacement short chop products on the market for example Mollichaff Donkey, Dengie Hi Fi Lite, Hi Fi Senior and Happy Hoof.

These products may be used to replace some or all of the donkey’s hay or straw ration. These short chop products are already chopped and generally very soft enabling them to be eaten by those donkeys with dental problems. Some donkeys might struggle even with these short-chopped products and therefore require a product that can be soaked down to form a sloppy consistency. A number of high fibre pellets can be soaked to form a soup like consistency, they can be soaked for up to 30 minutes and are easy for elderly donkeys to manage (eg Saracens Donkey diet, Spillers High Fibre Nuts). When selecting a high fibre pellet it is important to choose one that is safe for laminitics, most feed manufacturers will be happy to advise on this. Other products based on alfalfa and fibre that soak to a gruel may also be used, these products are useful for older donkeys needing extra condition as they are generally higher in calories than high fibre pellets (eg Fibre-Beet, Alfa-Beet).

Generally if donkeys are given products to replace or be fed alongside long fibres such as straw and hay they will cope very well. However, in some cases they may require other supplementary products.

A number of high fibre pellets (may also be known as fibre cubes or fibre nuts) can be soaked to form a soup like consistency; they can be soaked for up to 30 minutes and are easy for elderly donkeys to manage.

Generally if donkeys are given products to replace or be fed alongside long fibres such as straw and hay/ haylage they will cope very well, however, in some cases they may require other supplementary products

Some donkeys may require more calories than those that can be provided by a fibrous diet alone and may need additional feeds. There are a number of high energy alfalfa based chop products such as Alfa A, that may be used to supplement part of the fibre ration. 

Alfalfa products are not suitable for older donkeys with poor liver function; a vet can take blood samples to check liver function. Alfalfa can also be quite hard to chew, so be aware that donkeys with poor teeth may be at risk of choking. 

Vegetable oil based products are also an ideal way to ‘top up’ the energy content of a diet for donkeys without liver disease. The nutritional value of a feed can be increased by adding small amounts of soya or vegetable oil (up to 100ml per day). There are also high oil-based pellet products available that are excellent sources of calories, it is important to choose a cereal grain free product and feed in small quantities according to manufacturer’s instructions.

Although it is often tempting to feed cereal grain based coarse mixes they tend to be too high in energy and starch and too low in fibre so their use is not recommended. Feeding such products has been shown to be associated with an increased risk of problems such as gastric ulceration, laminitis and obesity. They can also be difficult for donkeys with poor teeth to chew causing them to choke.

Feed balancers are useful for donkeys on a forage only diet in providing them with the essential protein, vitamins and minerals that they may need. Some balancers will help with condition gain while other balancers will not promote weight gain and can be used as an important part of a weight reduction programme. When first introducing a balancer we recommended dampening it to prevent the donkey from bolting it down too quickly and choking.

Although donkeys are generally good eaters and enjoy most feeds given to them some elderly donkeys may need the addition of some extra ‘goodies’ to tempt them. It is important to only offer treats that elderly donkeys can manage. To tempt fussy donkeys, carrots, bananas and apples are invaluable; however, donkeys with poor teeth may struggle with them. Grated carrots and apples are ideal, however if this is not practical mashed, tinned carrots may be used or small amounts of unsweetened apple sauce may be helpful.

Donkeys enjoy soaked sugar beet added as a ‘top dressing’ to their normal diet. It is important to select an unmolassed sugar beet as the sugar content in traditional molassed sugar beet is too high for donkeys and may predispose them to problems such as laminitis. Another way to tempt fussy feeders is to use peppermint cordial, small amounts of this potent liquid are ideal to add to feeds to provide a pleasant aroma and taste for donkeys, this is particularly useful if you are trying to disguise medications.

Donkeys love polo mints and ginger biscuits, these products are great to tempt fussy feeders but care should be taken not to feed too many as they are very high in sugar and may lead to obesity and associated health problems. Older donkeys with poor teeth will also struggle to eat them.
