Horse Summer Grazing and Welfare

Summer grazing management for horses involves balancing nutritional needs against risks of laminitis from rich pasture, with welfare implications of both restriction and overgrazing.

Key Facts

Spring and summer pasture grasses are high in fructans that can trigger laminitis in susceptible horses
Laminitis is a painful and potentially crippling condition affecting the sensitive laminae of the hoof
Grazing restriction through muzzles or limited turnout reduces laminitis risk but restricts natural behavior
Horses at pasture show lower cortisol and better behavioral welfare indicators than stabled horses
Metabolically at-risk horses including ponies and those with PPID require individualized grazing management

Welfare Considerations

Summer pasture management requires individualized assessment balancing the welfare benefits of free movement and natural grazing against the serious welfare risk of laminitis. Blanket restriction approaches often restrict healthy horses unnecessarily, while metabolically vulnerable horses need tailored management. Grazing muzzles, if used, should allow sufficient intake and be fitted correctly to avoid causing pain or excessive restriction.

What You Can Do

Consult your veterinarian about laminitis risk assessment for each horse in your care
Use body condition scoring to guide summer grazing management decisions
Monitor at-risk horses with regular hoof health checks during high-sugar grass periods
Ensure grazing muzzles are correctly fitted and allow adequate water and grass intake
