Heat emergencies in livestock during extreme weather events require rapid response protocols to prevent mortality and severe welfare harm in housed and outdoor animals.
Heat emergency welfare requires both adequate permanent infrastructure and emergency response protocols for extreme events. Power failures in mechanically ventilated poultry and pig buildings can cause catastrophic mortality within hours in hot weather. Emergency backup systems, manual override capabilities, and rapid response protocols save animal lives during power failures. As climate change increases the frequency and severity of heat events, heat emergency preparedness transitions from contingency planning to essential welfare infrastructure. Insurance-linked welfare requirements for emergency cooling capacity are one policy mechanism to drive adoption.
