Poultry Litter Management: Welfare and Environmental Standards

Poultry litter quality directly affects bird welfare through contact dermatitis, respiratory health, and pathogen load, making litter management a frontline welfare intervention.

Key Facts

Wet, compacted litter causes footpad dermatitis affecting up to 80% of commercial broilers in worst-case scenarios
Hock burns and breast blisters from litter contact reduce bird welfare and downgrade carcass quality
Ammonia from wet litter causes respiratory irritation and eye damage at concentrations above 25 ppm
Good litter management including regular turning, ventilation, and partial replacement significantly reduces lesion prevalence
EU welfare regulations set maximum footpad lesion scores that trigger mandatory management improvement

Welfare Considerations

Litter quality is one of the most directly actionable welfare levers in poultry production — improvements are achievable at relatively low cost and have immediate, measurable welfare benefits. Footpad lesions causing pain during locomotion affect the majority of conventionally housed broilers, representing an enormous welfare burden that proper litter management can substantially reduce. Outcome-based litter welfare standards that trigger management changes when lesion rates exceed thresholds are more effective than input-based regulations alone.

What You Can Do

Choose chicken certified by standards requiring footpad lesion monitoring and litter quality management
Advocate for mandatory footpad lesion reporting as a welfare indicator in national poultry standards
Support research into optimal litter materials and management practices for different housing systems
