Horse Winter Blanket Management: Welfare and Thermoregulation

Blanket management decisions significantly affect horse welfare in winter, with over-blanketing being as problematic as under-blanketing in many circumstances.

Key Facts

Horses have a thermoneutral zone of approximately 5-25 degrees Celsius and regulate temperature efficiently
A horse's winter coat provides excellent insulation when dry — rain and wind are the primary heat loss threats
Over-blanketing causes sweating, overheating, and disruption of the natural coat insulation system
Clipped horses lose their natural insulation and require blanketing according to ambient temperature
Body condition score is a more reliable indicator of cold stress than air temperature alone

Welfare Considerations

Horse blanket management requires understanding individual horse factors including body condition, coat clip level, age, health, and access to shelter. Healthy, unclipped horses in adequate body condition rarely need blanketing above 5 degrees Celsius with access to shelter. Over-blanketing causes significant welfare harm through overheating, sweating, and skin condition problems. The primary welfare concern is not under-blanketing healthy horses but rather ensuring wet horses, thin horses, and clipped horses have appropriate protection.

What You Can Do

Assess body condition score and natural coat before making blanketing decisions
Provide good-quality shelter that blocks wind and rain as the primary protection strategy
Only blanket clipped, elderly, or underweight horses according to ambient temperature guidelines
Remove blankets daily to check for rubs, sweating, and skin condition under the rug
