Broiler Welfare Assessment: Outcome-Based Monitoring

Outcome-based welfare assessment for broiler chickens measures the actual welfare of birds through validated on-farm and at-slaughter indicators rather than just housing inputs.

Key Facts

Welfare Quality protocols assess broilers on 12 criteria including gait score and fearfulness
Gait scoring assigns a 0-5 score with 3+ indicating lameness and pain
Hock burn scoring at slaughter provides feedback on litter management quality
Mortality rates and culling frequency are indicators of chronic welfare failure
EU broiler welfare legislation requires regular on-farm monitoring but implementation varies

Welfare Considerations

Outcome-based welfare assessment identifies birds that are actually experiencing welfare compromises rather than assuming that meeting input criteria ensures welfare. Flocks with high gait scores have large proportions of birds experiencing chronic leg pain that prevents normal behaviour. Hock burn at slaughter reveals that birds spent excessive time in wet litter causing skin damage and pain. Fearfulness measures assess the quality of human-bird relationships affecting daily handling welfare. Regular outcome assessment identifies farms where welfare interventions are most needed.
