Litter quality in broiler and cage-free layer housing is a critical but often overlooked determinant of welfare, affecting footpad health, respiratory disease, dustbathing behavior, and the overall sanitary condition that influences flock wellbeing.
Litter quality represents a welfare multiplier in poultry housing because its condition affects multiple welfare dimensions simultaneously. Poor quality wet litter causes footpad dermatitis that creates painful lesions affecting locomotion and behavior throughout the production cycle. High ammonia from wet litter damages respiratory epithelium, increasing susceptibility to disease and causing eye irritation. Wet, compacted litter also fails to support dustbathing, denying hens the behavioral outlet that reduces the motivational frustration associated with this strongly motivated behavior. Good litter management requires adequate ventilation to control moisture, appropriate stocking density to prevent excessive moisture loading, prompt repair of leaking drinkers, and regular assessment of litter quality throughout the flock cycle. Welfare audits that include litter quality scoring provide a practical proxy for the quality of overall housing management.
