Farmed Broiler Litter Quality: Foot Health and Welfare Outcomes

The quality of bedding litter in broiler chicken houses directly affects foot pad health, leg disorders, and overall welfare. Wet, compacted litter causes painful lesions affecting millions of birds.

Key Facts

Foot pad dermatitis (FPD) caused by wet litter affects an estimated 30-80% of broilers in some production systems
Severe FPD lesions are associated with reduced movement and altered weight-bearing behavior indicating pain
EU regulations require monitoring of foot pad dermatitis at slaughter as a welfare indicator for flock management
Litter quality is influenced by drinker design, ventilation, stocking density, and flock health status
Fresh litter added to the house reduces FPD incidence significantly within days of application
Slow-growing breeds show lower FPD prevalence than fast-growing breeds at equivalent stocking densities

Welfare Considerations

Foot pad dermatitis is a preventable welfare problem that persists because the economic incentives for litter management do not always align with welfare outcomes. Producers bear the cost of litter management; the welfare harm is experienced by birds. Regulatory systems that impose financial penalties for high FPD rates at slaughter — as implemented in several Scandinavian countries — create the missing economic incentive. Welfare monitoring at slaughter provides herd-level feedback that enables targeted management intervention. Consumers who choose chicken from low-FPD certified producers send a market signal that rewards good litter management.

What You Can Do

Choose chicken from producers who publish foot pad dermatitis monitoring data as part of welfare certification
Support regulatory requirements that link FPD slaughter scores to financial penalties for producers
Advocate for drinker design standards that reduce water spillage and litter wetting in broiler houses
Support research into litter management practices that maintain quality throughout the production cycle
