Litter quality in poultry housing is a critical welfare determinant affecting millions of birds' foot and leg health.
The litter a broiler chicken stands on for its entire life is a fundamental welfare determinant. Wet, ammonia-saturated litter causes contact lesions that are demonstrably painful, affecting the way birds walk and behave. These conditions are largely preventable through appropriate stocking density, ventilation management, and litter maintenance. Footpad scoring at slaughter provides an objective welfare audit trail connecting farm management to animal outcomes.
