Poultry Heat Stress Management

Heat stress in poultry is a growing welfare concern as climate change increases ambient temperatures during the growing period.

Key Facts

Broilers begin panting at 25-27 degrees Celsius and are at mortality risk above 35 degrees
Heat stress reduces feed intake, growth, and immune function in broilers
Tunnel ventilation and evaporative cooling systems maintain acceptable temperatures
Drinking water temperature and availability is critical during heat events
Stocking density reduction during hot periods is a welfare-positive management adjustment

Welfare Considerations

Heat stress causes acute suffering and mortality in poultry that is worsening as climate change increases temperature extremes. Investing in adequate ventilation and cooling infrastructure is both a welfare and business imperative for the poultry sector.

What You Can Do

Support poultry producers investing in ventilation and cooling infrastructure
Advocate for maximum temperature standards in poultry welfare legislation
Choose poultry from producers with documented heat stress management protocols
