Livestock Welfare in Extreme Cold Events

Winter weather events including snowstorms and freezing temperatures create acute welfare challenges for outdoor and partially outdoor livestock - preparation and response planning protects animal welfare.

Key Facts

Livestock adapted to outdoor conditions can tolerate cold well when body condition is maintained and shelter is available
Hypothermia risk is highest in wet conditions - wind and moisture accelerate heat loss far more than temperature alone
Newborn lambs and calves are particularly vulnerable in the first 24 hours before thermoregulation is established
Deep snowfall can prevent livestock from accessing feed and water despite being otherwise healthy
Emergency feeding stores of at least 5 days' provision should be maintained during winter months
Early identification of hypothermia signs including shivering, staggering and withdrawal enables rapid treatment
Rewarming protocols using warm water baths, warming boxes and colostrum are effective for newborn hypothermia

Welfare Considerations

Livestock cold weather welfare planning is essential for any outdoor or partially outdoor system. The primary welfare risks are hypothermia in vulnerable individuals and feed and water deprivation during severe weather. Planning addresses both: ensuring shelter is available and functional, maintaining emergency feed reserves, identifying vulnerable animals requiring additional monitoring, and knowing how to respond to hypothermic individuals. Stockperson training in hypothermia recognition and treatment enables rapid response that saves welfare and lives. The welfare cost of inadequate preparation falls entirely on livestock who cannot advocate for themselves - the planning responsibility rests with farmers and animal keepers.

What You Can Do

Maintain emergency feed reserves of at least 5 days' supply before winter weather season
Ensure all livestock have access to functional shelter before cold and wet weather periods
Monitor pregnant and recently birthed animals particularly carefully during cold weather events
Learn hypothermia recognition and treatment protocols for the species you keep
Review and update emergency response plans annually before winter to address any infrastructure gaps
