The transition from farrowing crates to loose housing systems for sows around birth represents one of the most significant debates in modern pig welfare.
The farrowing crate debate captures a genuine welfare trade-off between sow welfare and piglet welfare. Sows in crates suffer significant restriction of fundamental behavioral needs — they cannot turn around, build nests, or perform natural farrowing behaviors. The suffering is chronic and measurable. However, loose farrowing in poorly designed systems increases piglet crushing mortality. The resolution is neither defending crates nor abolishing them without system-level change, but investing in the nest box designs, temperature management, and floor traction systems that allow loose farrowing to protect both sow welfare and piglet survival. This exists and works — the barrier is investment, not knowledge.
