Pig Farrowing System Welfare Advances

The conventional farrowing crate immobilises sows for 3-5 weeks around birth, and alternatives that preserve both piglet safety and sow welfare are being developed and adopted globally.

Key Facts

Conventional farrowing crates prevent sows from turning around for 3-5 weeks
Sow immobilisation causes significant frustration of nesting behaviour and postural restriction
Piglet crushing by sows is the primary justification for crate use, accounting for 5-10% piglet mortality
Welfare outcomes in loose farrowing systems depend heavily on pen design and management
Temporary confinement systems allow sow freedom before and after a short confinement period at birth
Sweden, Switzerland, and Norway have banned or heavily restricted conventional farrowing crates

Welfare Considerations

The farrowing crate welfare debate involves a genuine conflict between sow welfare and piglet survival that simple crate elimination cannot ignore. However, well-designed loose farrowing systems can achieve piglet mortality rates comparable to crate systems while allowing sows to express nesting behaviour and postural freedom. The challenge is that loose farrowing systems require higher management skill and investment in pen design. The welfare case for transition is strong: preventing sow suffering during the most physically demanding period of her reproductive cycle is ethically significant.

What You Can Do

Support producers and retailers committed to farrowing crate phase-out timelines
Choose pork products from producers using loose farrowing or temporary confinement systems
Advocate for farrowing crate phase-out commitments from major UK retailers and food service companies
Support research into pen design innovations that achieve piglet safety and sow welfare simultaneously
