Welfare evidence on alternatives to conventional farrowing crates in commercial pig production, including free farrowing systems, loose housing, and pen design innovations.
The farrowing crate is one of the most welfare-damaging devices in modern animal agriculture, causing severe and prolonged physical restriction for millions of sows worldwide. The scientific evidence is unambiguous: sows in crates are prevented from performing critical maternal behaviors including nesting, which causes measurable frustration and stress. Free farrowing alternatives — including various loose housing and modified crate designs — demonstrate that commercial pig production is viable without this extreme confinement. The challenge is economic: transition requires investment and expertise. Consumer pressure, retailer commitments, and policy mandates are all necessary to accelerate the shift. Welfare certification programs excluding farrowing crates provide the market signal needed to support progressive farmers.
