Horse Pasture Management and Welfare

Pasture quality and management significantly affect horse welfare through nutritional content, parasite burden, foot health, and behavioral opportunity, with both overgrazing and inappropriate pasture causing welfare problems.

Key Facts

Horses evolved to graze for up to 16 hours daily over large areas, a behavioral need difficult to meet on small paddocks
Laminitis, a severely painful foot condition, is often triggered by rapid intake of sugar-rich spring or autumn grass
Overgrazing creates muddy conditions that predispose horses to mud fever and digital dermatitis
Rotational grazing and resting pastures reduces parasite burden and maintains pasture quality
Track systems that provide movement while controlling grazing can improve both metabolic and behavioral welfare

Welfare Considerations

Pasture management has direct and significant impacts on horse welfare through multiple pathways. Laminitis from inappropriate pasture access is one of the most painful and debilitating conditions in horse medicine, caused entirely by management decisions around grazing access. Muddy conditions from overgrazing cause painful skin and foot conditions. Conversely, horses denied adequate turnout and grazing suffer from behavioral deprivation from one of their most strongly motivated natural activities. Balancing metabolic safety with behavioral welfare requires careful individual assessment and management.

What You Can Do

Restrict high-risk horses from lush spring and autumn pasture to prevent laminitis
Implement rotational grazing to maintain pasture quality and reduce parasite burdens
Provide track systems or limited grazing strips to balance metabolic safety with movement needs
Monitor pasture conditions and manage mud through appropriate fencing, surfacing, and drainage
Consult an equine nutritionist about appropriate grazing management for horses with metabolic conditions
