Sow Housing Reform: Gestation Crate Phase-Out and Group Housing Welfare

The transition from gestation crates to group housing for sows represents the most significant large-scale pig welfare improvement in progress globally.

Key Facts

Gestation crates — individual metal stalls 60 cm wide — prevent sows from turning around for most of pregnancy
The EU banned gestation crates for most of pregnancy in 2013; some US states and companies are following
Approximately 60% of US breeding sows are still housed in gestation crates
Sows in gestation crates show high rates of stereotypic bar-biting, depression-like behaviors, and bone weakness
Group housing provides welfare benefits but requires careful management to reduce aggression during mixing
Mixing unfamiliar sows causes fighting; stable groups with appropriate space and resources minimize conflict

Welfare Considerations

Gestation crate confinement represents one of the most severe welfare deprivations in commercial agriculture. A sow unable to turn around for four months of her pregnancy experiences chronic physical discomfort, muscle atrophy, bone weakness, and profound behavioral frustration. The stereotypic bar-biting — sows repeatedly biting the metal bars of their stalls — is a welfare indicator of the system's inadequacy. Group housing is not without challenges: sow mixing injuries require management. But the welfare calculus is clear — group housing with appropriate space, resources, and management provides vastly better welfare than individual gestation crates. The transition is technically feasible; the barrier is primarily economic and organizational.
