Gestation Crate Transition Welfare

The welfare implications of transitioning from individual gestation stalls to group housing for sows.

Key Facts

Individual gestation crates confine sows for most of their pregnancy with minimal movement
Group housing allows sows to move freely, express social behaviors, and turn around
Several countries and jurisdictions have banned or restricted gestation crates
Transition from crates to group housing requires careful management to prevent aggression
Electronic sow feeding systems allow individual feed allocation in group-housed sows
Welfare improvements in group housing are well-documented when transition is properly managed

Welfare Considerations

The shift from gestation crates to group housing represents one of the most significant welfare improvements achievable in pig production. Sows in crates cannot turn around, perform natural behaviors, or engage socially, leading to boredom, frustration, and physical deterioration. The welfare benefits of group housing are clear, but the transition must be managed carefully: aggression at mixing and competition for resources can create new welfare challenges if systems and management are not adequately designed. Best practice involves mixing sows at appropriate times in pregnancy, providing adequate space, hiding places, and individual feeding systems.

What You Can Do

Support pork producers that have already transitioned fully to group sow housing
Look for pork labeled as produced without gestation crates or from welfare-certified farms
Advocate for legislative bans on gestation crates in jurisdictions where they remain legal
Encourage retailers to set and publicly report timelines for gestation crate elimination in their supply chains
Support research into optimizing group housing systems to minimize aggression and maximize welfare
