Heat stress in cattle causes reduced productivity, immune suppression, and genuine suffering. As climate change intensifies, heat stress management is an increasingly critical welfare and production concern.
Heat stress in cattle is simultaneously a welfare emergency and a production problem, and the economic consequences of the latter drive most industry action on the former. But behind the productivity data is genuine animal suffering: cattle panting in 40C heat, clustering desperately for shade, unable to feed or rest normally, and experiencing physiological distress across multiple body systems. Climate change is making heat stress more frequent and more severe across major cattle-producing regions. Proactive heat stress management — shade, water, cooling systems, and adjusted feeding times — is both a welfare investment and an increasingly urgent adaptation to a warming climate.
