Gestation crates — individual metal stalls confining pregnant sows — represent one of the most contested welfare issues in modern animal agriculture, with major industry and regulatory transitions underway.
Gestation crate welfare has been more thoroughly documented than almost any other farm animal welfare issue, and the scientific verdict is clear: chronic confinement in individual stalls causes severe psychological and physical suffering. Sows cannot perform any natural behaviors — turning, rooting, foraging, social interaction, or nest-building. The bar-biting and head-weaving stereotypies seen in nearly all crated sows are neurological indicators of profound frustration and distress. Well-managed group housing systems with proper feeding management provide dramatically better welfare outcomes. Industry resistance to transition has been economic rather than welfare-based. Consumer pressure through corporate commitments has driven more change than legislation alone.
