Horse Pasture Management: Supporting Equine Health Through Land Stewardship

Pasture quality fundamentally affects horse health and welfare, with appropriate grazing management preventing obesity, laminitis, parasite burden, and nutritional deficiencies.

Key Facts

Horses evolved to graze for 16-18 hours daily, and limiting access to grazing causes behavioral and physical welfare problems
Improved pastures with high sugar content can trigger laminitis in metabolically susceptible horses
Overgrazing creates bare lots with parasite contamination that significantly increases worm burden
Rotational grazing systems that rest paddocks reduce parasite populations and maintain grass quality
Horses need at least 1-2 acres of pasture each to support meaningful grazing behavior
Winter supplementary forage management prevents weight loss and associated metabolic stress in horses without adequate pasture

Welfare Considerations

Pasture management is foundational to horse welfare because it determines the quality of the environment horses spend most of their lives in. Horses who spend hours in overgrazed, parasites-heavy paddocks or are restricted from grazing to prevent laminitis develop behavioral problems from frustrated grazing drives and physical problems from inadequate movement and nutrition. Good pasture management — rotational grazing, appropriate fertilization without excess, parasite management through manure removal and pasture spelling — maintains the land as a welfare asset rather than a welfare risk.

What You Can Do

Implement rotational grazing to maintain pasture quality and reduce parasite contamination
Remove manure from paddocks regularly to break parasite life cycles
Test pasture grass sugar content in spring and autumn when laminitis risk is highest
Provide adequate grazing area per horse — minimum 1-2 acres per animal
Monitor body condition scores regularly and adjust pasture access or supplementation accordingly
