Heat stress in cattle causes significant welfare impacts and production losses, making shade, water, and cooling interventions a welfare and economic priority.
Heat stress in cattle causes multiple simultaneous welfare harms: elevated body temperature causes discomfort and physiological stress; reduced feed intake causes metabolic disruption; seeking shade disrupts normal grazing patterns; and reproductive suppression reduces calf viability. These are not abstract production concerns but real suffering. As climate change increases the frequency and intensity of heat events, investing in shade, cooling systems, and appropriate stocking density becomes an increasingly urgent welfare requirement for livestock farmers globally.
