Comparing zero-grazing and pasture-based cattle systems reveals complex welfare trade-offs. Evidence-based comparison informs management and policy decisions.
Neither zero-grazing nor pasture-based cattle systems are inherently welfare-superior - management quality determines outcomes in both. Pasture systems enable natural behavior but expose cattle to weather extremes and pasture-borne disease. Zero-grazing systems can precisely manage nutrition and health but restrict movement and behavior. Hybrid systems combining seasonal grazing with high-welfare winter housing may offer the best of both approaches.
