Gestation crates confine pregnant sows almost immobile for months at a time, and their phase-out is one of the defining campaigns of the farm animal welfare movement.
Sows in gestation crates cannot perform natural behaviours such as rooting, nesting, or social interaction. Chronic confinement causes stereotypic behaviours (bar-biting, repetitive head movements), indicating severe frustration and stress. Welfare science is unequivocal: group housing systems with adequate space and enrichment significantly improve sow welfare. The gap between corporate commitments and actual supply chain implementation remains a major accountability challenge.
