Nutrition and dietary management of equine gastric ulcer syndrome.

Equine gastric ulcer syndrome (EGUS) is common in horses. Diagnosis is based on history, clinical signs, gastroscopic examination, and response to treatment. Effective pharmacologic agents are available to treat EGUS, but more comprehensive measures of environmental and dietary management are needed to decrease ulcer severity and recurrence. This article provides an understanding of dietary components and how feeds interact with stomach mucosal barrier function to cause EGUS. In addition, a secondary goal is to provide information on how diet and environmental management can reduce ulcer severity and prevent recurrence in horses with EGUS.
