The phase-out of gestation crates for sows represents one of the most significant farm animal welfare reforms of recent decades.
The gestation crate ban represents significant welfare progress for pregnant sows, who previously were confined so tightly that they could not turn around throughout pregnancy. The shift to group housing with appropriate space and resources addresses fundamental mobility and social needs. However, welfare benefits of group housing depend critically on management quality - poorly managed groups can cause aggression and stress that undermines the welfare intent of the reform.
