Pig Farrowing System Welfare Innovations

Farrowing crates that confine sows during birth and lactation are the next major target of pig welfare reform. Innovative systems that protect piglets while giving sows more freedom are being developed.

Key Facts

Farrowing crates confine sows for 3-5 weeks around birth and lactation in most commercial systems
Sows in farrowing crates cannot turn around, build a nest, or perform natural maternal behaviors
Crates are used to reduce piglet crushing by sow, which is a genuine welfare and production challenge
Loose farrowing systems do result in higher piglet crushing rates without careful design
PigSAFE and other welfare-conscious farrowing systems have reduced crushing rates close to crate levels
Denmark has passed legislation requiring loose farrowing systems by 2035

Welfare Considerations

Farrowing crates cause the same fundamental welfare problems as gestation crates: complete prevention of natural behavior during a period of high motivation for nesting and maternal care. Sows in farrowing crates show high levels of frustration behavior related to thwarted nesting drive. The welfare costs must be balanced against piglet welfare implications of loose systems. Research into improved loose farrowing design has made substantial progress, with systems achieving crushing rates comparable to crates while allowing sow behavioral freedom. The regulatory and industry trajectory points toward loose farrowing as the future standard, with welfare science guiding the transition.
