Pig Farrowing Pen Advanced Welfare Evidence

Advanced welfare evidence from free-farrowing pen trials is providing the data needed to support industry transition away from farrowing crates with maintained animal welfare outcomes.

Key Facts

Large-scale European trials of free-farrowing systems including PigSAFE and UPigS show piglet mortality comparable to crate systems with appropriate management
The critical welfare improvement factors in successful free-farrowing systems are pen design, staffing expertise, and sow selection
Farrowing index including total born, born alive, and pre-weaning survival provides comprehensive welfare outcome data
Pre-farrowing nest building behavior fully expressed in free-farrowing systems correlates with shorter, less complicated farrowings
Denmark has implemented a national phase-out of farrowing crates with documented transition challenges and lessons
Research from Denmark, Sweden, and the Netherlands provides a growing evidence base for successful transition management

Welfare Considerations

Advanced welfare evidence from free-farrowing trials provides the factual foundation for policy and industry transitions that were previously resisted on the grounds of insufficient evidence. The Danish national experience demonstrates that transition to free-farrowing systems is achievable at scale with appropriate producer support, and that the welfare improvements to sow welfare are real and measurable even when the transition requires careful management attention to maintain piglet survival. The evidence consistently shows that pen design matters more than system type: well-designed free-farrowing pens achieve better welfare outcomes for both sow and piglets than poorly designed ones. This knowledge is now available to guide effective transition policy and producer investment decisions.

What You Can Do

Support pork producers who have successfully transitioned to free-farrowing systems and can demonstrate welfare outcomes
Advocate for phase-out timelines with adequate transition support for producers moving away from farrowing crates
Choose pork certified to standards requiring free-farrowing or crate-free systems with documented welfare monitoring
Support research programs evaluating free-farrowing system designs and management practices that optimize both sow and piglet welfare
