At Risk: All Domestic Horses
However, all domestic horses are at risk. Studies show between 11-37% of recreational riding horses also have EGUS. | Photo: iStock
Risk Factor: Weaning
An estimated 50% of foals and weanlings have gastric ulcers. Weanlings are susceptible due to the stress of being separated from their dams, as well as from changing diet during this life stage transition. | Photo: Anne M. Eberhardt/The Horse
Risk Factor: Highly Concentrated Diets
Grain-based diets with large, infrequent meals that are highly concentrated put horses at risk for EGUS. | Photo: Anne M. Eberhardt/The Horse

Forage First
The equine digest system is designed for foraging and grazing. Slow feeders or haynets can help lengthen the time horses spend eating, which can be an effective strategy for managing EGUS. | Photo: Courtesy Dr. Krishona Martinson/University of Minnesota Report
Forage First
Forage-based diets with frequent feedings are best for reducing EGUS risk. | Photo: Thinkstock
Alfalfa as an Antacid
Alfalfa is high in calcium, which can buffer stomach acid and offer relief for horses suffering from EGUS. You can feed alfalfa in hay, pellet, or cube form. | Photo: iStock
Prevention and Treatment
Ulcergard and Gastrogard (omeprazole) are the only FDA-approved products used to prevent and treat EGUS, respectively. | Photo: Erica Larson/The Horse
