The transition to slower-growing broiler breeds is one of the most significant ongoing farm animal welfare reforms.
The shift to slower-growing broiler breeds represents potentially the most impactful single reform in the history of farm animal welfare advocacy. Fast-growing breeds cause endemic suffering through cardiac failure, metabolic disease, and mobility problems affecting virtually every bird. Slower-growing breeds eliminate these problems substantially. Corporate commitments covering billions of chickens annually are real progress, but require consumer and civil society pressure to ensure fulfillment on schedule.
