Gestation crates confine pregnant sows in spaces too small to turn around. Global phase-out progress has been significant but uneven — understanding where the welfare fight stands is essential for effective advocacy.
The gestation crate phase-out represents one of the most significant farm animal welfare policy achievements of the past two decades — and one of the clearest examples of sustained advocacy producing measurable change. The welfare science is unambiguous: sows in gestation crates cannot perform fundamental movement behaviours for the majority of their pregnancies, generating chronic frustration and psychological distress visible in stereotypic bar-biting and rooting behaviour. The transition to group housing, while presenting management challenges, reliably improves welfare outcomes when done properly. Progress globally has been substantial but uneven — the EU and several other jurisdictions have legally mandated change, while the US, despite significant corporate commitments, lacks federal legislation. Corporate commitments from food companies including McDonald's, Walmart, and Subway have driven faster change in some markets than legislation alone. The welfare advocacy lesson is that parallel legal and market-pressure strategies are more effective than either alone.
