Heat stress in cattle causes significant welfare compromise and production losses, yet shade provision remains inadequate on many farms despite simple, cost-effective solutions being available.
Heat stress in cattle is a welfare problem that is simultaneously preventable, widespread, and increasingly serious under climate change. The suffering associated with heat stress — elevated body temperature, respiratory distress, reduced feed intake, immunosuppression, and in extreme cases death — affects enormous numbers of cattle in warming production regions each summer. The provision of shade, which is the most basic requirement for cattle welfare during hot weather, remains absent on many farms where it is most needed. As climate change extends hot weather periods, the welfare case for mandatory shade provision and improved heat stress management becomes more urgent with each passing year. Consumer expectations of welfare-certified products should include heat stress management standards as a minimum requirement in affected regions.
