Broiler Chicken Ammonia Exposure and Respiratory Welfare

High ammonia levels in broiler sheds cause significant respiratory damage and eye problems, reducing welfare and productivity.

Key Facts

Ammonia at 25 ppm causes measurable eye and airway damage in broilers
Litter moisture and stocking density drive ammonia production
Adequate ventilation can maintain ammonia below 20 ppm
Respiratory damage increases susceptibility to bacterial infections
EU welfare codes recommend keeping ammonia below 20 ppm

Welfare Considerations

Chronic ammonia exposure causes painful irritation to broilers' eyes and respiratory tracts, impairing breathing and reducing activity. Good litter management and ventilation are essential preventive measures.

What You Can Do

Support poultry welfare standards requiring ammonia monitoring
Choose chicken from farms with verified ventilation standards
Advocate for mandatory ammonia limits in national poultry codes
