Pig Gestation Crate Reform: Science and Policy Progress

Gestation crates for sows represent one of the most contested practices in modern agriculture, with a strong scientific consensus on welfare harms driving significant legislative and corporate policy change worldwide.

Key Facts

Standard gestation crates measure approximately 0.6 x 2.2 meters, preventing sows from turning around
Sows in crates show elevated stress hormones, bone weakness, muscle atrophy, and stereotypic behaviors
The EU banned gestation crates for most of pregnancy in 2013; some countries have complete bans
Over 70 major food companies have made commitments to eliminate gestation crates from their supply chains
Group housing with proper management shows equivalent or better reproductive performance to crates
Transition costs and group management complexity are the primary barriers cited by producers

Welfare Considerations

The welfare science on gestation crates is among the most conclusive in animal agriculture: the severe restriction of movement causes documented physical harm through muscle and bone deterioration, and psychological harm evidenced by high rates of stereotypic behaviors and behavioral indicators of chronic frustration. While the transition to group housing requires management changes, the welfare benefit is significant. Corporate and legislative commitments represent genuine progress, but enforcement and verification remain challenges.
