Ventilation failures in poultry barns can kill thousands of birds in hours - improving prevention, monitoring and emergency response is a critical welfare priority for the industry.
Ventilation failure represents one of the most acute catastrophic welfare risks in poultry farming. Birds in high-density housing have no ability to escape rising temperatures and rapidly experience severe heat stress before dying. Prevention through reliable equipment maintenance, alarm systems and backup power is far more effective than emergency response. Welfare auditing bodies increasingly require evidence of robust contingency planning. The welfare case for lower stocking densities is reinforced by the reduced mortality risk when ventilation failures occur.
