Global progress on phasing out gestation stalls for pregnant pigs has been significant but uneven, with major producers still using full confinement systems.
Gestation stall phase-outs represent one of the most significant legislative welfare improvements for farm animals in recent decades. Confining pregnant sows in individual stalls for months — unable to turn around, perform nesting behavior, or engage in any social interaction — caused chronic physical and psychological suffering. The EU ban and voluntary corporate commitments have together affected millions of sows. The large-scale adoption of group housing demonstrates that productive pig farming without total confinement is commercially viable. The unfinished task involves extending protections to the majority of the world pig herd outside current regulatory reach.
