Horse Grazing Enrichment and Behavioral Needs

Why horses need adequate grazing time and how to meet behavioral needs when full turnout is not possible.

Key Facts

Wild horses spend 16-18 hours per day grazing, using their digestive system nearly continuously
Stabled horses restricted from grazing develop gastric ulcers at rates of 60-90% in performance horses
Stereotypic behaviors such as cribbing, weaving, and box walking develop in response to inadequate grazing time
Horses are designed to move while eating, and static feeding positions contribute to respiratory and spinal problems
Forage should constitute a minimum of 1.5% of body weight daily to meet digestive and behavioral needs
Slow-feeder haynets and enrichment feeding devices extend foraging time when turnout is restricted

Welfare Considerations

Equine welfare fundamentally requires meeting the behavioral need to graze and move. Modern management systems that stable horses for 20-23 hours per day and feed concentrated meals twice daily are profoundly misaligned with equine behavioral needs. The resulting gastric ulcers, stereotypic behaviors, and metabolic disorders represent chronic welfare failures. Even when full pasture turnout is not possible, welfare can be improved through ad libitum forage, slow feeders that extend meal time, and regular opportunities for movement and social interaction.

What You Can Do

Provide horses with a minimum of 2-4 hours of turnout daily, more wherever possible
Use slow-feeder systems to extend foraging time when horses must be stabled
Feed forage as the majority of the diet to support digestive and behavioral health
Seek veterinary assessment for gastric ulcers in horses showing girthiness, reluctance, or poor condition
