Gestation crates prevent sows from turning around for their entire pregnancy. The global transition to group housing is one of the most significant welfare reforms in modern pig farming.
Gestation crates represent one of the most clear-cut welfare problems in modern agriculture. Pregnant sows confined individually for 16 weeks at a time cannot walk, turn, or engage in any natural social or foraging behavior. The result is chronic physical and psychological suffering measurable through stereotypic behavior rates, cortisol levels, and cardiovascular fitness assessments. Group housing allows sows to walk, socialize, and perform species-typical behaviors. Welfare outcomes in group systems depend heavily on management quality: adequate space, appropriate group composition, individual feeding control, and skilled stockpeople are all necessary. The welfare case for group housing is unambiguous, and the practical barriers are real but surmountable.
