Pig Farrowing System Reform and Sow Welfare

The welfare case for moving away from farrowing crates toward systems that allow sow natural behavior.

Key Facts

Farrowing crates confine sows in a space too small to turn around for 4-6 weeks around each birth
Approximately 75% of pigs farmed in the US are born in farrowing crate systems
Sows in farrowing crates cannot perform nest-building behavior, a strongly motivated pre-farrowing drive
Sow frustration from crate confinement is expressed as stereotypic bar-biting and repetitive oral behaviors
Loose-housing farrowing systems including PigSAFE and Comfort Sow achieve comparable piglet mortality with far better sow welfare
Several European countries including Sweden have banned or severely restricted farrowing crate use

Welfare Considerations

Farrowing crate welfare reform is one of the highest-impact campaigns in farmed animal advocacy because it addresses a severe welfare compromise affecting millions of breeding sows. The scientific case against farrowing crates is strong: sows show acute stress from confinement, cannot perform motivated nest-building behavior, and develop chronic musculoskeletal problems from immobility. The industry argument that crates reduce piglet crushing is addressed by well-designed alternative systems. Consumer pressure, legislative change, and corporate commitments are all accelerating farrowing crate reform across major pig-producing countries.

What You Can Do

Choose pork products from farms with documented farrowing crate-free systems
Support campaigns by Humane Society and RSPCA for farrowing crate bans
Advocate for government legislation phasing out farrowing crate use
Reduce conventional pork consumption until farrowing crate-free alternatives are more available
