Livestock Heat Abatement System Welfare

Heat abatement systems in livestock housing are essential welfare investments as climate change intensifies summer temperatures.

Key Facts

Dairy cows start experiencing heat stress at 22 degrees Celsius and relative humidity above 50%
Cooling systems including fans, sprinklers, and shade reduce heat stress significantly
Heat stress during gestation reduces calf birth weight and immune function
Return on investment from heat abatement systems is positive within 2-3 years

Welfare Considerations

Dairy cows experiencing heat stress show reduced feed intake, increased respiration rate, and reduced lying time that compromise welfare and production simultaneously. Calves born to heat-stressed mothers have reduced passive immunity and lifetime productivity. Climate change is extending heat stress seasons and increasing severity. Investment in cooling systems delivers welfare benefits and positive economic returns.

What You Can Do

Support dairy farms with documented heat abatement systems
Advocate for heat stress mitigation requirements in dairy welfare standards
Choose dairy from farms with shade, ventilation, and cooling as standard
