New free-farrowing system designs are proving that sow freedom and piglet survival can be achieved together, making the welfare case for crate elimination commercially compelling.
Free-farrowing system innovation has fundamentally changed the welfare-versus-productivity debate around farrowing crates. The argument that crates were necessary to protect piglets from crushing has been substantially weakened by evidence from well-managed alternative systems achieving comparable survival rates. The welfare case for the sow — able to turn, nest-build, and express maternal behavior — combined with viable commercial alternatives removes the primary justification for continued crate use. Retailer commitments with firm deadlines are now the most powerful lever for accelerating adoption.
