Gestation crates confine pregnant sows in spaces too small to turn around. Despite welfare science consensus against them, they remain widespread. Understanding the reform landscape matters.
Gestation crates represent one of the clearest welfare failures in industrial animal agriculture: scientific consensus on the harm is unambiguous, welfare alternatives are commercially proven, and bans have been implemented in multiple jurisdictions without catastrophic production consequences. Yet in the United States and other major pork-producing countries, the majority of breeding sows remain in gestation crates throughout most of their 16-week pregnancies. The behavioral consequences — stereotypic behaviors, muscle weakness from immobility, psychological frustration — are well documented. Corporate supply chain commitments and state-level ballot initiatives are the most effective current levers in jurisdictions where federal legislation has not acted.
