Generally healthy, fit donkeys do very well on a basic diet of good quality feeding straw and limited access to grass and hay/haylage if required.
Many donkeys live until 30 years and beyond and the accepted classification for a ‘geriatric’ donkey is one that is over 20 years old. This is more the case in donkeys kept as companions rather than as working donkeys, but in both situations they deserve, and need, special care.
The thick coat of the donkey and its stoic nature often means that problems go unnoticed and a drop in body condition or even a loss of appetite may not be easily visible.
They need free access to food and fresh clean water at all times and it is important to note that the nutrient requirements change as the donkey ages, along with their ability to chew long fibres. Supplementary feed may become necessary.
Before making any changes to your donkey’s diet it is important to consult your veterinary surgeon to ensure that there are no underlying medical conditions that may be causing your donkey to drop weight or condition. It is important to ask your vet or equine dental technician to check your donkey’s teeth at least once a year. Elderly donkeys may have loose or missing teeth, which can make it difficult for them to chew long fibres such as straw or hay - in these cases feeding alternative fibres sources may be of benefit.
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.
Donkeys that require more calories than those provided by the products listed above may need to be fed additional products. There are a number of high energy alfalfa-based chop products such as Alfa A, Alfalfa Chaff and Dr Green that may be used to supplement part of the fibre ration. These products are usually short chopped and are suitable for older donkeys with relatively good teeth (alfalfa can be quite hard to chew). 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 the above products can all be increased by feeding small amounts of soya or vegetable oil (up to 100 ml per day). There are also high oil-based products available that are excellent sources of calories. It is important to choose a cereal grain-free product such as Equijewel and feed in small quantities.
Although it is often tempting to feed cereal grain based coarse mixes it is important to avoid these products. Donkeys do not require the high sugar and starch levels provided by such products and may become predisposed to problems such as gastric ulceration, laminitis and obesity.
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.
Feeding hints and tips
The following hints and tips are important to remember when feeding your donkey:
- Continually assess your donkey’s body condition, using the donkey specific body condition scoring chart, and make changes to their diet accordingly.
- Make sure that fresh, clean water is available at all times. It is important to ensure your donkey is drinking enough, sometimes in the winter donkeys may not want to drink very cold water and you may need to provide tepid water to tempt them.
- Always introduce changes to the diet gradually and watch your donkey to ensure that it is eating.
- Meals of less than 500 g of supplementary feed are ideal for a 200 kg donkey. Try to avoid feeding as one meal, small frequent meals are best.
- If you are not feeding a forage balancer, ensure that the donkeys have access to an equine specific non-molassed mineral lick.
