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:
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.
Forage provides at least half of your horse’s diet, so it’s a good idea to know the facts –and fiction- about forage.
Our horse nutrition experts provide advice for feeding horses with allergy or intolerance.
The main aim is to use feeds that are easy to chew, highly digestible and palatable to the horse. Ideally, a diet high in energy and protein should be supplied to try and restore the weight and condition that is inevitably lost.
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 temperatures forecast to be below zero and snow fall for areas of the country, ensuring your horse or pony is kept warm and going about your normal routine can be a challenge.
There is concern regarding a potential forage shortage this winter. Many ran out of forage before the end of last winter and a dry summer has seen the early use of hay and haylage harvested this year. So if you find yourself short of hay and haylage this winter then what’s the alternative?
