Horse Pasture Management: Welfare Through Appropriate Grazing

Pasture management is central to horse welfare — both overgrazing and inappropriate pasture present significant risks.

Key Facts

Horses are evolved for continuous low-intensity grazing for up to 16-18 hours daily
Modern improved pasture grasses contain much higher sugar levels than native grasses, increasing laminitis risk
Strip grazing, track systems, and sacrifice areas allow grazing access control without full grass deprivation
Horses in bare paddocks with no grazing opportunity develop stereotypies and psychological distress
Seasonal pasture management — restricting access during spring flush — reduces metabolic disease risk
Social grazing with compatible companions supports natural behaviour and reduces stress

Welfare Considerations

Pasture access is a fundamental welfare need for horses that simultaneously presents management challenges in domesticated settings. Modern improved pasture presents laminitis risks that wild horses do not face because their natural forage has lower sugar content. Welfare-positive pasture management balances the need for grazing with sugar intake management through strip grazing, track systems, and winter hay provision. Complete deprivation of grazing — horses kept entirely on concrete or in bare paddocks — creates significant psychological welfare problems including stereotypy development. The challenge is providing grazing opportunity while managing quantity, not eliminating it.

What You Can Do

Assess your pasture sugar content during high-risk periods using a portable refractometer
Use strip grazing or a track system to provide grazing access with quantity control
Never deprive horses of all grazing without providing compensatory hay enrichment
Monitor body condition score monthly and adjust grazing access accordingly
Test grass nitrogen and sugar levels in spring before turning horses onto lush pasture
