Over the last decade, research has increased our understanding of Equine Gastric Ulcer Syndrome, more commonly referred to as ulcers in horses.
More recently, two distinct diseases have been identified which affect different areas of the stomach: Equine Squamous Gastric Disease (ESGD) and Equine Glandular Gastric Disease (EGGD). Whilst we know the risk factors for ESGD, less is understood about EGGD.
Symptoms of ulcers in horses are not always very easy to distinguish from other issues or diseases, but some common ones include weight loss, dull coat, biting when being girthed and intermittent colic. However, it is important to understand that good doers and overweight horses can have ulcers, too. It is also apparent that there is no link between the severity of ulcers and the symptoms – some horses are clearly very stoic with grade 4 ulcers and no signs of any problems visible on the outside!
Feeding strategies that increase the risk of gastric ulcers in horses:
Feeding horses with ulcers is focussed on reducing risk factors – follow these top tips to keep your horse healthy:
A consensus statement was published by specialists representing the European College of Equine Internal Medicine (ECEIM) about EGGD. It stated that there is no proven link between diet and EGGD but it was recommended to implement the same feeding strategies as for squamous gastric ulcers in horses (outlined above). In addition the following advice was given:
At Dengie all of our feeds are naturally low in starch but we are often asked about starch levels in other feeds and how to work out the amount of starch a horse is consuming each day. We have devised a simple tool that allows you to input the details relating to your horse’s diet. Click here to work out your horse’s current starch intake.
Absolutely! Alfa-A Oil is our highest energy feed at 12.5MJ DE per kg which is comparable to a competition or conditioning mix. However, it contains around 10 times less starch than a cereal based feed with a comparable energy value so is much better for gut health. The fibre and oil provide slow release energy and so you may find that your horse’s behaviour and focus improves too – a study we supported a few years ago showed that horses on fibre and oil based diets were less reactive to novel stimuli than those on a cereal based ration. Don’t just take our word for it though. 4* eventer Lucy Jackson has competed at the highest level on a fibre based diet!
If you can turn out on good grazing then that would be a great starting point. In addition it would be good to get some alfalfa into his ration as it is a natural buffer to acidity. There are some pelleted versions of alfalfa that you can use: pure Alfalfa Pellets can be fed dry or dampened with water if he prefers them that way or Alfa-Beet which is a combination of unmolassed sugar beet and alfalfa which must be fed soaked before feeding. Although a horse would tend to consume a pelleted/soaked version of alfalfa more quickly than chopped fibre and therefore spend less time chewing, the main aim in this situation is to increase fibre intake and find a form of fibre your horse likes. Once the ulcers have healed you may find your horse’s appetite picks up a bit and you can try introducing some chopped fibre again.
The minimum amount of forage your horse should ideally be consuming is 1.5% of her bodyweight. To try to promote good gut health the total daily ration should be divided into as many small offerings as possible so the period of time she isn’t eating is as short as possible. Research by Luthersson and colleagues showed that if the time between eating was more than 6 hours, the risk of ulcers increased.
Straw can be a really useful feed material for good doers as it provides “chew-time” without too many calories. In the study by Luthersson and colleagues, they also found that when straw was the sole source of forage it increased the incidence of ulcers. However, the important part of this finding was that straw was the only type of forage fed. There is no reason why straw can’t be used alongside other forages such as alfalfa and grass hay to increase fibre intake for good doers. Feeds such as Hi-Fi Lite or Hi-Fi Molasses Free would therefore be suitable options for your horse.
Yes – providing it is fibre based. The advice is to give a scoop of chopped fibre within 30 minutes prior to exercise. This recommendation is given to make sure that the fibrous mat within the horse’s stomach is maintained to reduce acid splashing about in the stomach. Acid splash in the squamous or non-glandular lining of the horse’s stomach is linked to gastric ulceration. Ideally this chopped fibre should include alfalfa as research has shown that alfalfa particularly is a superior buffer to acidity within the digestive tract.
The main advice for managing horses with gastric ulcers is to reduce the amount of non-structural carbohydrate (starch + sugar) in the ration and feed more fibre. Using unmolassed sugar beet is one way of achieving this especially for horses that are working or struggling to maintain condition.
With so much feeding and management advice now available for owners of horses with Equine Gastric Ulcer Syndrome (EGUS), Dengie commissioned a survey in 2018 to explore awareness and use of the key feeding and management strategies recommended.
The Dengie nutrition team have put together their top tips for feeding the ulcer prone horse which should be implemented alongside any medication that your vet has prescribed.
Healthy Tummy is the ULTIMATE fibre feed to promote gut health in horses and ponies. A complete, high-calorie fibre feed that fuels work and promotes condition and also contains the latest ingredients known to promote gut health. Here are 5 key benefits you might not have known about Dengie Healthy Tummy.
Leisure horses are not immune to gastric ulcers and on the Dengie Feedline we have regular enquiries regarding managing gastric ulcers in horses that manage their weight very easily. This in some ways can actually be more challenging to manage, especially if the horse also needs to lose weight!
