The debate over farrowing crates versus loose housing systems centers on competing welfare concerns for both sows and piglets during the critical birth period.
The farrowing crate debate illustrates how welfare can involve genuine trade-offs between the welfare of parent and offspring. Sows confined in farrowing crates cannot turn around for the 3-5 weeks of lactation, cannot build nests, and cannot interact fully with their piglets — all significant welfare costs. Yet loose housing without proper design increases piglet crushing mortality. The resolution lies not in accepting either extreme but in investing in well-designed loose farrowing systems that use pen geometry, substrates, and nest boxes to minimize crushing while restoring sow behavioral freedom. Research shows that experienced sows in quality loose systems achieve comparable piglet survival to crate systems while benefiting substantially in their own welfare.
