Livestock Heat Abatement Systems

Heat abatement systems for livestock including fans, misters and cooling showers are effective welfare interventions with documented benefits.

Key Facts

Evaporative cooling systems can reduce cattle body temperature by 1-2 degrees C in hot weather
Soakers and fans together are more effective than either alone for heat stress reduction
Cooled dairy cows show higher milk production, improved fertility and better health outcomes
Capital investment in cooling infrastructure is offset by productivity improvements in many climates

Welfare Considerations

Heat abatement systems directly reduce the suffering of heat-stressed animals. The evidence base is clear and the technology is proven — cooling systems work and the animals benefit measurably. The welfare case for heat abatement investment is strongest for dairy cattle who generate significant metabolic heat from milk production. As climate change increases the frequency and severity of heat events, heat abatement investment becomes increasingly important for farm animal welfare.

What You Can Do

Support dairy and beef operations investing in heat abatement infrastructure
Advocate for heat abatement requirements in welfare certification standards
Ask dairy suppliers about their cooling systems and heat stress management protocols
Support research into cost-effective heat abatement options for smallholder producers
