Farrowing crates confine sows during birth and nursing, preventing piglet crushing but severely restricting sow movement. The welfare trade-offs and alternatives to this system are at the center of pig welfare reform.
The farrowing crate debate encapsulates the core tension in farm animal welfare between individual animal experience and production efficiency. Sows in farrowing crates cannot perform nesting behavior — a powerful pre-farrowing motivation — and are unable to lie down freely, causing frustration and distress. Chronic confinement during the three-to-four-week nursing period causes muscle weakness and stereotypic behavior. However, transitioning to loose systems requires careful design to prevent piglet crushing, particularly in the critical first days after birth. Research shows that well-designed free farrowing pens with appropriate flooring, nest areas, and temperature management can achieve acceptable piglet survival while dramatically improving sow welfare. The reform trajectory is clear; the challenge is supporting the industry transition.
