Farrowing Crate Alternatives: Welfare Evidence for Loose Housing of Sows

Farrowing crates severely restrict sow movement during and after birth. Evidence increasingly supports loose housing alternatives that preserve welfare for both sow and piglets.

Key Facts

Farrowing crates restrict sow movement to prevent crushing of piglets by the sow lying down.
Sows in farrowing crates cannot perform nesting behaviour despite strong pre-farrowing motivation.
Loose farrowing systems including Scandinavian pens use physical design to protect piglets differently.
Pre-farrowing nesting behaviour satisfies a highly motivated drive — its prevention causes distress.
Piglet mortality in well-designed loose farrowing systems is comparable to crated systems.
Norway, Sweden and Switzerland have phased out or severely restricted farrowing crate use.

Welfare Considerations

Farrowing crates represent one of the starkest welfare-production trade-offs in agriculture. The sow's confinement addresses a real safety concern for piglets but at the cost of the sow's ability to express one of her strongest behavioural drives. Evidence from Scandinavian countries demonstrates that loose farrowing pens designed with slope angles, nest areas and escape routes for piglets can achieve comparable piglet survival with dramatically better sow welfare. The welfare case for transitioning away from farrowing crates is strong, and investment in stockperson training and pen design delivers systems where both sow and piglet welfare are protected.

What You Can Do

Choose pork from producers using loose farrowing systems rather than conventional crates.
Support campaigns for farrowing crate bans and government funding for transition support.
Engage with retailers about their commitments to farrowing crate-free supply chains.
Learn about the successful models in Norway and Sweden as examples of achievable reform.
Donate to farm animal welfare organisations lobbying for farrowing crate reform.
