Livestock Heat Stress Prevention

Heat stress in livestock causes production losses, health problems, and significant welfare compromise. Climate change is increasing the frequency and severity of heat stress events.

Key Facts

Heat stress occurs when animals cannot dissipate body heat fast enough to maintain normal temperature
Dairy cows, pigs, and poultry are particularly vulnerable to heat stress
Heat stress reduces feed intake, fertility, milk production, and immune function
Panting is an early indicator; rapid breathing, lethargy, and collapse indicate severe heat stress
Cooling systems including shade, fans, misters, and sprinklers significantly reduce heat stress

Welfare Considerations

Livestock experiencing heat stress suffer from elevated body temperature, physiological distress, and in severe cases organ failure. Climate change is making heat stress events more frequent and severe globally, affecting outdoor and indoor systems alike. The welfare burden of heat stress extends beyond individual animals to population-level impacts on reproduction, development, and longevity. Preventive cooling investment is both a welfare requirement and a production necessity as climates warm. Emergency protocols for extreme heat events save lives and reduce suffering.

What You Can Do

Ensure adequate shade, ventilation, and water access for all livestock during summer
Develop emergency heat protocols including enhanced ventilation and cooling for extreme events
Avoid housing livestock in poorly ventilated buildings during heat waves
Support research into climate-resilient livestock breeds and housing design
Advocate for heat stress prevention requirements in farm animal welfare legislation
