Farmed Pig Housing Transitions: From Gestation Crates to Group Systems

The global transition away from gestation crates toward group housing for pregnant sows represents the largest ongoing farm animal welfare reform in history.

Key Facts

The EU banned gestation crates after the first 4 weeks of pregnancy in 2013; several EU states banned them entirely
Over 1,000 US food companies have pledged gestation crate-free supply chains by various target dates
Group housing requires management expertise to prevent aggression during mixing of unfamiliar sows
Research shows group-housed sows have better bone strength, cardiovascular health, and behavioral outcomes
Transition costs for group housing conversion are significant but one-time investments with long-term welfare benefits

Welfare Considerations

Gestation crates confine pregnant sows in spaces too small to turn around for most of their 16-week pregnancies, preventing virtually all natural behavior. The physical and psychological harm of this confinement is well-documented through physiological stress measures and behavioral abnormalities. Group housing eliminates this confinement but introduces new welfare challenges including mixing aggression and resource competition requiring careful management. The overall welfare balance strongly favors group housing despite transition challenges. Consumer pressure and corporate pledges have driven more welfare progress in this area than regulatory action in many markets, demonstrating the power of supply chain accountability.

What You Can Do

Choose pork products from gestation crate-free suppliers as a minimum welfare standard
Support food companies that have published verifiable gestation crate-free supply chain commitments
Advocate for US federal legislation banning gestation crates to establish baseline protections
Reduce pork consumption overall while supporting producers making genuine welfare transitions
