Farrowing crates restrict sow movement during and after birth to reduce piglet crushing. Understanding welfare trade-offs and alternatives guides the industry toward better systems.
Farrowing crate welfare science presents a genuine dilemma: piglet welfare (crushing risk) versus sow welfare (confinement). Sows in farrowing crates display intense frustrated nesting behavior — pawing at bars, rooting air — for hours before farrowing, a clear welfare indicator of severe behavioral deprivation. The evidence base for alternatives is growing: well-designed free farrowing pens with appropriate anti-crushing features achieve piglet mortality rates comparable to crates in skilled management hands. PigSAFE, developed by Newcastle University, and similar systems demonstrate that the sow welfare costs of full confinement can be avoided without sacrificing piglet survival. The key challenge is management skill — free farrowing systems require more attentive stockpersonship. Transitioning the industry requires investment in training, facility redesign, and regulatory frameworks that mandate alternatives.
