Livestock Shade and Heat Stress Prevention

Heat stress in livestock causes significant suffering, production losses, and mortality. Providing shade and cooling is a high-impact welfare intervention with aligned economic benefits.

Key Facts

Cattle experience heat stress at temperatures above 25 degrees Celsius when combined with high humidity
Heat stress causes reduced feed intake, reduced milk production, and impaired reproduction in dairy cattle
Feedlot cattle without shade suffer elevated mortality during extreme heat events
Pigs are particularly susceptible to heat stress as they cannot sweat and have limited thermoregulatory capacity
Poultry houses require ventilation management to prevent heat-related mortality in warm weather
Climate change is increasing the frequency and severity of heat events affecting livestock globally

Welfare Considerations

Heat stress in livestock causes acute and chronic suffering through physiological stress responses, behavioral changes, and in severe cases death. Cattle panting and bunching in shade during heat events demonstrates visible discomfort. Confined animals without shade or cooling access cannot use behavioral thermoregulation and suffer more severely. Providing shade structures in feedlots costs relatively little compared to the mortality and production losses prevented. Evaporative cooling in dairies significantly reduces heat stress and improves welfare and milk production simultaneously. Climate change makes heat stress management increasingly important as extreme temperature events become more frequent.

What You Can Do

Support welfare certification schemes requiring shade provision for all livestock in warm climates
Advocate for heat stress management requirements in livestock welfare regulations
Choose beef and dairy products from farms with documented shade and cooling provisions
Support climate action policies that reduce the frequency of extreme heat events affecting livestock
