Climate change is intensifying heat stress in livestock, making effective heat abatement infrastructure a critical and increasingly urgent welfare requirement for farm animals.
Heat stress causes genuine suffering in farm animals — it is not merely a productivity issue. Physiologically, heat-stressed animals experience increased respiration rates, elevated cortisol, reduced feed intake, and in severe cases, organ failure and death. As climate change increases frequency and intensity of heat events, baseline heat abatement infrastructure that was adequate in the past becomes insufficient. Welfare-conscious farm management requires proactive infrastructure investment in shade, ventilation, and cooling systems before heat emergencies occur, combined with emergency response protocols for extreme events.
