The UK has committed to phasing out farrowing crates. Understanding the practical challenges and solutions for transitioning to loose farrowing systems informs the policy debate.
The farrowing crate phase-out is a significant policy challenge because the welfare calculus is genuinely complex. Crates restrict sow movement and deny nest-building behaviour - clear welfare costs. Loose farrowing can increase piglet crushing - a clear welfare risk. The welfare outcome of transition depends entirely on implementation quality: pen design, sow selection, management protocols and farmer skill all determine whether loose farrowing delivers better or worse welfare than crates. The evidence from established loose farrowing systems shows that good outcomes are achievable. The policy challenge is ensuring that the transition is properly supported so that sow welfare improves without creating a piglet mortality welfare problem.
