Pig Farrowing Systems: Sow Welfare and Piglet Safety

Farrowing (giving birth) represents one of the most significant welfare challenges in pig farming, with conventional crate systems severely restricting sow movement while free-farrowing alternatives improve welfare.

Key Facts

Conventional farrowing crates confine sows in a space barely larger than their body for 4-5 weeks around birth
Sows cannot turn around, build nests, or perform natural maternal behaviors in conventional crates
Nest-building before birth is a highly motivated behavior — sows denied materials show repetitive bar-biting as a substitute
Free-farrowing systems allow sow movement but require management to reduce piglet crushing risk, which is higher without crates
Research finds similar piglet mortality rates between well-managed free-farrowing and crate systems — the traditional justification for crates is weakened
Switzerland has banned farrowing crates since 2007 — Sweden, Norway, and parts of Australia also restrict their use

Welfare Considerations

Farrowing crate confinement is among the most severe welfare restrictions in commercial pig farming. A sow that cannot turn around, cannot build a nest, and cannot investigate her environment for 4-5 weeks around the most physiologically demanding period of her life is experiencing significant behavioral deprivation. The argument that crates prevent piglet crushing is legitimate but addressable through free-farrowing system design and management. Countries that have banned crates have demonstrated this is feasible without unacceptable production losses. Consumer demand for "crate-free" or "free-farrowing" pork supports this welfare transition.

What You Can Do

Choose pork from farms using free-farrowing systems, increasingly labeled on premium products
Support campaigns for farrowing crate bans in your jurisdiction
Ask retailers about their suppliers' farrowing system commitments and timelines for crate-free production
Reduce pork consumption or shift spending toward producers with documented crate-free farrowing
