Horse Winter Nutrition Welfare | Animal Welfare Hub

How winter nutrition management affects horse welfare and what best practices ensure adequate body condition through cold months.

Key Facts

Horses require 50-100% more calories in cold weather to maintain body temperature
Forage fermentation in the hindgut generates heat and is preferable to grain supplementation in cold
Thin horses entering winter are at much higher risk of cold stress and health complications
Body condition scoring in autumn allows proactive nutrition adjustments before winter
Access to unfrozen water is critical — horses can become dangerously dehydrated in freezing temperatures

Welfare Considerations

Winter nutrition management is a welfare priority for horses in temperate and cold climates. Horses are hindgut fermenters well-adapted to cold if provided adequate forage, but thin body condition and inadequate feed provision leads to cold stress, immune suppression, and weight loss spirals that compromise welfare significantly. Providing ad libitum hay, checking water sources regularly to prevent freezing, and increasing caloric density for horses that struggle to maintain weight are all evidence-based winter welfare practices.

What You Can Do

Body condition score your horse in early autumn and adjust nutrition before winter
Provide ad libitum hay to maintain gut motility and body heat through fermentation
Check water sources daily in freezing weather and use heated water buckets if needed
Increase caloric density through oil or beet pulp supplementation for horses losing condition
