Does Your Horse Have Gastic Ulcers?

Does Equine gastric ulcer syndrome (EGUS) affects 60-90% of adult horses and 25-50% of foals and weanlings. The condition collectively refers to sores or erosions that develop when portions of the horse’s sensitive stomach lining get exposed to stomach acid. The equine stomach secretes acid continually, putting horses at risk of developing gastric ulcers when they’re not consuming enough roughage to neutralize that acid.
