Litter quality in broiler houses directly affects bird welfare through footpad health, ammonia levels, and disease risk. Proper management significantly reduces suffering.
Broiler litter welfare illustrates how a single management variable — litter moisture — can cause widespread suffering across entire flocks. Wet litter contacts the skin of birds that spend their lives on the floor, causing chemical burns that progress from mild redness to open, painful lesions on feet and hocks. Elevated ammonia from wet litter causes chronic respiratory irritation and eye damage. The connection between stocking density and litter quality is direct — high stocking densities produce more waste per unit area, worsening moisture management. Monitoring footpad lesion scores provides a practical welfare audit that many certification schemes now require, creating a feedback mechanism between litter management quality and auditable welfare outcomes.
