Horse Pasture Welfare: Grazing Behavior and Nutritional Management

Pasture access is fundamental to equine welfare, but management must balance behavioral needs for grazing with metabolic health requirements that vary significantly between individuals.

Key Facts

Horses are trickle feeders evolved to spend 16-18 hours daily grazing small amounts of fibrous forage
Horses in stables without forage access develop stereotypies and gastrointestinal problems within hours
Spring grass with high non-structural carbohydrates triggers laminitis in metabolically sensitive horses
Slow feeders and track systems extend grazing time while limiting intake for metabolically at-risk animals
Pasture management including rotation and forage species selection affects both nutritional quality and welfare

Welfare Considerations

Pasture welfare for horses requires balancing two competing needs: the behavioral imperative for continuous grazing movement and the metabolic requirements of horses with insulin dysregulation or laminitis risk. Horses denied all pasture access suffer behavioral frustration; those given unrestricted access to rich spring grass may develop acute laminitis. Track systems, strip grazing, and slow feeder hay provision allow continuous movement and trickle feeding while controlling carbohydrate intake. The individual metabolic profile of each horse should determine pasture management rather than one-size-fits-all approaches.

What You Can Do

Ensure horses have access to appropriate forage for a minimum of 16 hours daily in some form
Have metabolically at-risk horses assessed by a veterinarian before spring pasture turnout
Implement slow feeders and track systems to extend foraging time while managing intake where needed
