Gastric Ulcers in Horses and How to Manage it

Nowadays, well over half of the horses suffer from stomach problems – from foals to recreational horses to high-performance athletes.

A topic that you should pay attention to as a horse owner. You can counteract the problem yourself by optimizing the type of housing and supporting measures in feeding.


Numerous horses suffer from stomach ulcers and a sensitive stomach. This is no longer just a problem for racing and sport horses, but can also occur in all horses for leisure horses. The causes are often several factors that trigger the disorder in the stomach. In addition to stress caused by posture, transport, training, and competition, some medications also cause stomach problems. With this information in mind it is always good to look out for the best supplement for gastric ulcers in horses available in the market.


Stomach ulcers in horses often become noticeable through recurring colic, uncomfortable feed intake (horses often consume concentrated feed better than hay), poor performance, general poor feed condition with reduced muscle formation, bad coat, and changed behavior. Diarrhea can also occur.

Can feeding be a cause of gastric ulcers in horses?

Yes, stomach ulcers can have feeding-related causes: for example, when feeding too little roughage, roughage of poor quality, and/or too much concentrate. Besides, (too) hasty eating or restlessness during feed intake can be part of the cause. Correct feeding, therefore, supports the treatment plan and makes a decisive contribution to recovery; Errors in feeding are always at the expense of the already stressed horse’s stomach.



To protect the stomach, targeted feeding is of great importance if the stomach is sensitive. Stomach-sensitive horses should therefore always have sufficient quantities of hygienic hay available. At least 2% hay based on body weight is necessary for the daily feeding and this amount should be divided over at least 3 meals per day. Pasture is recommended during the summer months. It is also important to always feed the horse the hay before the crib feed, so the stomach pH can be regulated and the crib feed can be digested better. The selection of the crib feed deserves special attention. Highly digestible alfalfa is particularly well-proven due to its balanced pH-stabilizing minerals. Prebiotic substances such as linseed and brewer’s yeast should not be missing in the daily feeding of stomach-sensitive horses to harmonize the stomach naturally. Stomach-sensitive horses often tend to have poor muscles or suffer from difficult muscle building. The supply of essential amino acids and high-quality protein components should therefore be provided through feeding. We recommend using highly digestible cereals as cereals to effectively fill the energy reserves with a small amount of feed. Rounded off with a special mixture of highly effective vital substances (essential minerals, vitamins, and trace elements), even horses with sensitive stomachs enjoy the best vitality and joy of movement!
