Horse Feeding Ecology: Beyond Hay and Hard Feed

Equine feeding welfare extends beyond nutritional adequacy to encompass behavioral feeding ecology including time budget, forage variety, and social feeding dynamics.

Key Facts

Horses evolved to spend 16-18 hours daily foraging, requiring continuous access to forage for digestive and behavioral health
Gastric ulcers develop within hours of an empty stomach as acid contacts unprotected stomach lining
Social feeding in natural herds allows horses to observe food selection choices of experienced companions
Forage variety including different grass and herb species provides nutritional and behavioral enrichment
Slow feeder nets extending hay consumption time significantly reduce stereotypy and ulcer development

Welfare Considerations

Horse feeding welfare is inadequately addressed by simply providing adequate nutrition. The behavioral dimension of equine feeding ecology, centered on continuous trickle feeding and social foraging, is as welfare-relevant as nutritional content. Horses fed twice daily in large meals experience hours of gastric acid accumulation without buffering forage, behavioral frustration from unfilled foraging drives, and social isolation from natural group feeding dynamics. Slow feeders, forage variety, and management approaches that extend feeding time toward the natural 16-18 hours significantly improve both behavioral and gastrointestinal welfare simultaneously.

What You Can Do

Ensure horses have access to forage for at least 16 hours daily using slow feeders where needed
Provide forage variety including different hay types and browse where safe and available
Use slow feeder haynets to extend consumption time and reduce gastric ulcer risk
Consider social feeding arrangements that allow horses to forage in compatible groups
