Heat stress is a major and growing welfare problem in broiler chicken production as climate change increases temperature extremes. Prevention and management reduce suffering significantly.
Broiler heat stress will become an increasingly serious welfare problem as climate change progresses. Fast-growing breeds with high metabolic rates are particularly vulnerable. Adequate ventilation, evaporative cooling, reduced stocking density during hot weather, and modified feeding schedules all reduce welfare costs. Future-proofing broiler production against climate change requires investment in heat management infrastructure now.
