What should I feed my horse if I suspect Gastric ulcers?

If you suspect your horse has ulcers veterinary advice should always be sought and, if needed, your vet will prescribe treatment.  You may like to also read our detailed article on gastric ulcers, which explains the anatomy of the horse’s stomach, discusses why ulcers occur, how they are graded and the common signs. This article also provides in-depth advice on how to manage and feed horses prone to ulcers.

It is important that horses prone to ulcers receive an adequate supply of forage, ideally ad lib.   This will ensure a continuous production of saliva, which helps to buffer stomach acid and provides natural protection to the non-glandular squamous portion of the stomach.  It is particularly important to ensure your horse has access to forage prior to exercise as this helps to provide a ‘fibre mat’ and reduces the risk of acid splash damaging the stomach lining during exercise.

In terms of hard feed, it is important to feed a low starch, high fibre ration, ideally one that has been specifically formulated to support gastric health. We recommend choosing a feed from our Care range.  All the feeds in our Care range are low in starch and contain a long-lasting, natural gastric acid buffer.  They also contain added yeast and two prebiotics to help support overall digestive health. Our Care range includes feeds that are suitable for all types of horses and ponies.  To discuss your horse’s individual needs and which Care feed is most suitable for them please contact our Nutrition team
