Cattle Heat Stress Management

Heat stress in cattle reduces welfare, productivity, and health, and is an increasing concern under climate change.

Key Facts

Cattle experience heat stress above temperature-humidity index of 68
Heat stress reduces milk yield, fertility, and immune function
Black or dark-coloured cattle are more susceptible to heat gain
Shade, cooling fans, and sprinklers effectively reduce heat load
Pregnant cows and calves are most vulnerable to heat stress

Welfare Considerations

As global temperatures rise, heat stress in cattle is an increasing welfare concern. Animals under heat stress show elevated respiration rates, reduced feed intake, and immune suppression. Providing shade, access to cool water, and mechanical cooling significantly improves welfare and reduces suffering during hot weather.

What You Can Do

Advocate for mandatory shade and cooling provisions
Support research into heat stress mitigation strategies
Promote awareness of heat stress signs among farmers
Support transition to climate-resilient housing systems
Encourage welfare audits that include thermal comfort assessment
