Cattle Welfare in Hot and Humid Climates

Cattle in tropical and subtropical production systems face chronic heat stress welfare challenges requiring breed selection, management and infrastructure adaptation.

Key Facts

Bos taurus cattle breeds are less heat tolerant than Bos indicus and crossbreeds
Shade provision and water cooling significantly reduce heat stress indicators
High producing dairy cattle in tropical climates face greater heat stress risk
Sprinkler cooling systems combined with forced ventilation provide effective relief
Genomic selection for heat tolerance is advancing in dairy cattle breeding programmes

Welfare Considerations

Chronic heat stress in tropical and subtropical cattle production causes sustained welfare harm including reduced feed intake, reproductive failure and elevated cortisol. Breed selection, infrastructure and management adaptations reduce welfare impact. Climate change is extending heat stress zones globally.
