Heat Stress Prevention Through Water and Cooling Systems

Water-based cooling systems including soakers, misters, and shade are the most effective heat stress mitigation for livestock, with significant welfare and productivity benefits.

Key Facts

Dairy cows experiencing heat stress produce 10-25% less milk and have higher rates of metabolic disease
Soaker systems that wet the cow's back and apply fans reduce heat stress more effectively than shade alone
Sheep with heavy fleeces are at particular risk in warm weather before shearing
Poultry buildings require active ventilation and cooling to prevent heat-related mortality in summer

Welfare Considerations

Heat stress cooling is one of the most well-established and cost-effective welfare interventions in livestock farming. The welfare benefits of effective cooling — reduced panting, maintained lying time, normal feeding behaviour — translate directly into production metrics that justify investment. The most effective systems wet the animal's skin and use fan circulation for evaporative cooling; shade alone provides insufficient relief in high humidity conditions. As climate change increases the frequency and intensity of heat events, cooling infrastructure transitions from a production luxury to a welfare necessity.

What You Can Do

Support welfare standards that require effective cooling systems as mandatory in hot climates
Advocate for heat stress plans as a required component of farm welfare assessment
Choose products from farms with documented heat stress management
Support climate-resilient livestock farming research including heat-tolerant breed development
