Horse Feeding Behavior and Digestive Welfare

How feeding management that respects equine digestive physiology protects horse welfare.

Key Facts

Horses are hindgut fermenters that evolved to consume small amounts of fibrous forage continuously
The equine stomach produces acid continuously and is not protected by buffering when empty
Feeding large concentrate meals creates rapid fermentation and acidosis risk in the hindgut
Horses fed twice daily large meals spend up to 14 hours without forage, causing gastric acid damage and ulcers
Trickle feeding using ad-lib hay or slow feeders mimics natural feeding patterns and protects digestive health

Welfare Considerations

Equine digestive welfare depends on feeding management that aligns with the horse's evolved physiology rather than human convenience. The horse's digestive system is designed for continuous small-volume forage intake — the stomach is small, acid-producing, and unprotected when empty. Feeding schedules that concentrate calories into two large daily meals create extended fasting periods that allow acid to damage the vulnerable squamous mucosa and create the conditions for gastric ulcers and hindgut acidosis. Trickle-feeding approaches using slow feeders, track systems, or multiple small hay rations throughout the day protect digestive health while providing the behavioral benefits of extended foraging. The welfare investment in appropriate feeding management pays returns in lower ulcer prevalence, better behavior, and improved overall health.

What You Can Do

Provide ad-lib hay using slow feeders that extend consumption time throughout the day and night
Avoid leaving horses without forage access for extended periods, particularly overnight
Minimize concentrate feeding and substitute with high-fiber alternatives where possible
Feed any necessary concentrates in multiple small meals rather than one or two large portions
Consult an equine nutritionist about feeding strategies that balance performance needs with digestive welfare
