Poultry Litter Quality and Respiratory Health

Litter quality in commercial poultry houses directly affects respiratory health, hock burn, and overall broiler welfare.

Key Facts

Ammonia levels above 25 parts per million cause respiratory damage in broiler chickens
Wet litter causes hock burn affecting up to 80% of birds in poorly managed flocks
Adequate litter management reduces both respiratory disease and footpad dermatitis simultaneously
Stocking density is the primary determinant of litter moisture and ammonia generation
European welfare standards set maximum ammonia levels and require litter monitoring records

Welfare Considerations

Litter quality is a proxy welfare indicator that captures multiple systems simultaneously. Poor litter creates a cascade of welfare harms: respiratory disease, painful skin lesions, and eye irritation from ammonia. Good litter management is achievable at modest cost and is one of the most impactful single-variable interventions in broiler welfare.

What You Can Do

Support poultry welfare standards that specify maximum ammonia levels and litter inspection requirements
Choose chicken products certified under standards requiring regular environmental welfare monitoring
Advocate for mandatory litter quality records as part of farm welfare assurance scheme requirements
