The quality of litter in poultry houses directly affects footpad health — wet, ammonia-rich litter causes painful hock burns and footpad dermatitis that affect the majority of commercial broilers in poorly managed systems.
Footpad dermatitis causes painful lesions that impair mobility and increase time spent resting, worsening contact dermatitis in a self-reinforcing cycle. Birds with severe footpad lesions show reduced activity and feeding behavior consistent with pain. The condition is largely preventable through litter management — making it a welfare indicator that reflects the quality of farm husbandry directly and measurably.
