Engineering solutions combined with management strategies provide effective heat stress mitigation for livestock facing increasingly extreme temperatures.
Heat stress causes acute suffering and can be rapidly fatal. But the welfare harm extends beyond acute heat events - chronic mild heat stress reduces feed intake, productivity, immune function, and reproductive performance, representing ongoing welfare compromise that is less visible than mortality. Investment in heat mitigation infrastructure protects animal welfare and farm viability simultaneously. As climate change intensifies, heat abatement is transitioning from optional enhancement to welfare necessity for livestock operations in warm regions.
