Gastric ulcers is a common problem affecting the equine population. The full name for gastric ulcers is equine gastric ulcer syndrome (EGUS) and it is made up of two forms; Equine glandular gastric disease (EGGD) and equine squamous gastric disease (ESGD). This defines the regions where the legions occur. EGGD refers to ulcers in the glandular, acid secreting lower part of the stomach. ESGD refers to ulcers in the upper, non- acid secreting part of the stomach, covered by a type of tissue called squamous epithelium.


Gastric ulcers in horses can present in a number of different ways including:

  • poor performance,
  • changes in behaviour or bad behaviour,
  • poor weight gain,
  • irregularity of gait,
  • girthing pain,
  • picky appetite,
  • resistance to riding aids,
  • colic,
  • poor coat quality


If you have any concerns about your horse’s health or gastric ulcers we would always advise consulting your vet.

Management and nutrition tips to help prevent the occurrence of gastric ulcers:

  • reduce stress
  • provide as much turnout as possible
  • provide ad lib forage
  • feed a high fibre, low starch diet
  • allow your horse to have some forage or a short chopped fibre prior to exercise to help create a fibre mat in the stomach
  • if your horse needs extra energy oil is a safer energy source than starch
  • if your horse needs a starch based feed, split this up into several smaller meals throughout the day. Ideally starch should be fed at no more than 100g per 100kg bodyweight per meal
  • you could also consider using a pre and probiotic supplement to help support the hind gut

Remember only a vet can diagnose and treat gastric ulcers, and veterinary advice should always be sought if you have any concerns about your horse’s health.


Find out below how two of our customers have got on with Pure Feed since having their horse treated by their vet for gastric ulcers:


Kerry started feeding Pure back in March after her mare was diagnosed with ulcers. She completed an online diet plan and now purchases from her local stockist in Durham.

Kerry said:

“My mare was diagnosed with ulcers in March this year after a few colic occurrences during a tough winter, colic wasn’t our only symptom that something was wrong she was getting progressively aggressive towards life.  We underwent a lot of treatment to get Nancy clear of ulcers but her attitude remained the same, despite upping here chaff intake as recommended. I began doing a lot of research into her symptoms which was an absolute mind field but a lot of the information came back to Alfalfa intolerance so with this I decided I really needed to try a diet change which is when I found Pure Feed. Having been on Pure Condition for only 12 weeks I think the results speak for themselves! 

Nancy is now happier than ever! Natural feed is the way forward “
