Welfare of Animals During Extreme Cold Events

Extreme cold weather events create acute welfare crises for farm animals, particularly in regions unaccustomed to severe winter conditions.

Key Facts

Cold stress in cattle and sheep increases maintenance energy requirements by up to 30%
Wind chill is the primary driver of cold stress in farm animals rather than temperature alone
Young animals including lambs and piglets are most vulnerable to hypothermia
Shelter provision reduces cold stress mortality significantly in all species

Welfare Considerations

Cold weather welfare failures occur when animals lack adequate shelter, nutrition, or dry bedding to maintain body temperature during extreme events. Hypothermia in neonates — particularly lambs born during late-winter storms — causes significant mortality and suffering. Adult cattle and sheep can tolerate cold temperatures with wind protection and adequate feeding, but may suffer when shelter is insufficient, bedding is wet, or feed intake is inadequate to cover elevated maintenance requirements. Climate change is increasing the frequency of extreme weather events including unexpected cold snaps in normally mild regions, requiring farmers to maintain preparedness year-round.

What You Can Do

Ensure farm animals have access to dry shelter and wind protection before cold weather events
Advocate for cold weather welfare standards in farm inspection programs
Support farmers in cold-vulnerable regions with infrastructure investment for emergency shelter
Monitor newborn animals closely during cold weather and intervene promptly for hypothermic individuals
