Cattle Heat Stress Monitoring: Technology and Welfare Management

Heat stress in cattle causes significant welfare harm and production losses. Technology-enabled monitoring and management strategies are improving outcomes across dairy and beef systems.

Key Facts

Temperature-humidity index above 68 begins to impair dairy cow welfare
Core body temperature above 39.5 C indicates significant heat stress
Automated collar sensors can detect elevated body temperature in real time
Misters, fans, and shade reduce heat stress in dairy cows by up to 60%
Heat stress affects reproduction, reducing conception rates by up to 20%
Climate change is increasing the frequency and severity of heat stress events globally

Welfare Considerations

Heat stress in cattle causes acute suffering, chronic immune suppression, and reproductive failure. Animals in regions experiencing increasing climate warming face growing heat burden without management intervention. The economic and welfare case for heat abatement infrastructure is strong and well-documented. Monitoring technology allows early intervention before severe physiological stress occurs.

What You Can Do

Support dairy farms investing in heat abatement infrastructure
Advocate for heat stress management plans as a requirement in dairy welfare standards
Choose dairy products from farms with documented climate adaptation programmes
