Broiler Ventilation Welfare: Air Quality and Respiratory Health

Poor ventilation in broiler houses causes respiratory disease, eye irritation and thermal stress. Good air quality is fundamental to broiler welfare.

Key Facts

Ammonia from litter can reach harmful levels above 25 parts per million
High carbon dioxide concentrations reduce bird activity and welfare
Dust in poorly ventilated houses causes respiratory tract irritation
Modern tunnel ventilation can reduce heat stress mortality significantly
Negative pressure ventilation systems maintain consistent air movement
Smart ventilation controlled by sensors optimises bird welfare and energy use

Welfare Considerations

Air quality profoundly affects broiler welfare. Ammonia causes painful eye and respiratory tract irritation at concentrations common in poorly managed houses. Carbon dioxide accumulation causes lethargy and distress. Birds in well-ventilated houses show better feather condition, lower mortality and greater activity.

What You Can Do

Support broiler welfare standards with maximum ammonia concentration limits
Choose chicken from welfare-certified producers with ventilation requirements
Advocate for real-time air quality monitoring in commercial broiler houses
Encourage adoption of precision ventilation technology in poultry industry
