Gestation crates confine pregnant sows in spaces too small to turn around for their entire pregnancies, causing severe welfare harm.
Gestation crates represent confinement so extreme that the animal literally cannot change position. Sows cannot turn around, cannot engage in rooting or foraging, cannot form social relationships, and exist in a state of permanent physical restriction. The psychological consequences are severe and well-documented: stereotypic behaviors in 80%+ of crated sows indicate chronic frustration and psychological suffering equivalent to clinical depression.
