Heat Abatement in Livestock Production

As global temperatures rise, heat abatement infrastructure for farm animals is increasingly important — protecting welfare and productivity during extreme heat events.

Key Facts

Shade, fans, and sprinklers are the primary heat abatement technologies for cattle and pigs
Cooling in the dry period — the two months before calving — improves calf health and subsequent milk production
Heat stress in the third trimester of pregnancy impairs fetal development in cattle and pigs
Water access is the most critical heat abatement measure; water intake increases 2-3x during heat stress
Climate projections suggest heat stress events will become more frequent and severe in most major livestock-producing regions

Welfare Considerations

Heat abatement is both a welfare imperative and an economic investment for livestock producers. Heat-stressed animals suffer physiologically and behaviourally — seeking shade and standing in water points at the expense of feeding and social interaction. Chronic heat stress impairs reproduction, immunity, and growth. Simple interventions — additional water points, shade structures, and fans — can significantly reduce thermal stress at modest cost. As climate change intensifies heat events, proactive investment in heat abatement infrastructure will become essential for both welfare and commercial viability.

What You Can Do

Support certification standards that require heat abatement plans as part of farm welfare protocols
Advocate for heat abatement requirements in livestock housing licensing
Choose meat and dairy from producers who document and invest in heat management
Support research into cost-effective heat abatement technologies for different production systems
Engage with climate change as a livestock welfare issue in your advocacy and communications
