Free-farrowing systems allow sows to move, nest, and interact with piglets naturally. Research and commercial experience show that well-designed free systems achieve good welfare without unacceptable piglet losses.
The farrowing crate represents one of the most significant confinement welfare problems in agriculture: a sow who cannot turn around for weeks at a time, cannot build a nest, and cannot respond to her piglets normally. The welfare case for eliminating crates is overwhelming. The practical case — that free-farrowing can achieve acceptable piglet survival rates — is increasingly demonstrated by commercial farms and research programs operating free systems. The remaining barrier is not technical feasibility but economic inertia and risk aversion by producers and retailers. Consumer and legislative pressure that rewards free-farrowing adoption is the most powerful driver of change.
