Footpad dermatitis affects the majority of broiler chickens and provides a reliable, measurable indicator of farm welfare conditions.
Footpad dermatitis causes chronic pain with each step. Severely affected birds walk less, drink less, and eat less. The lesions bleed and can become infected. FPD is essentially a welfare monitoring tool embedded in the animal: it records the history of conditions experienced by the bird across its lifetime. Slaughterhouse monitoring of FPD prevalence provides data on farm welfare without requiring expensive farm inspections.
