The quality and appropriateness of feed for farmed animals directly affects health, behavior, and welfare outcomes, with nutritional deficiencies and inappropriate diets causing widespread preventable suffering.
Feed management sits at the intersection of production optimization and welfare — in well-managed systems these goals align, but in systems optimized primarily for short-term production, feed decisions cause welfare harm. High-concentrate cattle diets produce faster growth at the cost of chronic gut discomfort. Feed restriction in broiler breeders produces manageable body condition at the cost of chronic hunger. Inappropriate fiber levels in pigs and rabbits produce cost savings at the cost of gut health and behavioral welfare. In each case, the welfare cost is borne by the animal and the economic benefit goes to the producer. Welfare standards that specify feeding requirements by behavioral and health outcome rather than just composition provide better protection.
