Litter quality in broiler chicken housing is a critical welfare factor affecting ammonia exposure, foot health, and disease rates. Evidence-based management reduces suffering.
Litter quality is one of the most directly welfare-significant management variables in broiler production. Chickens that spend their entire 42-47 day lives sitting and walking on wet, ammonia-laden litter develop foot pad dermatitis (painful foot sores), hock burns (contact wounds on the legs), and respiratory tract damage from ammonia inhalation. These are not rare problems - they affect significant proportions of commercial flocks even in well-managed facilities. The welfare impact is chronic: every hour spent on poor litter causes ongoing irritation and potential pain from existing wounds. Litter management through appropriate stocking density, drinker management, ventilation, and regular fresh litter addition represents a practical, farm-level welfare intervention with measurable outcomes. Hock burn scoring has become a standard welfare audit metric precisely because it reflects litter management quality.
