Farrowing crates confine sows during birth and nursing, preventing piglet crushing but causing significant welfare deprivation; alternatives are proving commercially viable.
Farrowing crate welfare issues are severe: sows confined for 3-5 weeks cannot perform any natural behavior including turning around, building nests, or moving away from their piglets. The frustration is evident in high rates of stereotypic behavior. The piglet safety argument is legitimate but overstated — well-designed free-farrowing systems with appropriate nesting materials, heat lamp areas, and pen dimensions achieve piglet mortality rates comparable to crate systems. Countries that have banned crates (Austria, Switzerland, Sweden) have maintained commercially viable pig production. The transition requires investment in barn redesign and management training, but the welfare case is compelling. Free-farrowing systems also improve piglet welfare by allowing normal maternal behavior and bonding.
