Pig Group Gestation Housing: Implementation Challenges

The global transition from individual gestation stalls to group housing for breeding sows offers welfare benefits but requires careful management to succeed.

Key Facts

The EU banned individual gestation stalls for sows beyond 4 weeks of pregnancy in 2013
Group housing allows sows to move, socialize, and express natural behaviors
Poorly managed group housing can increase aggression, injuries, and feeding competition
Electronic sow feeding (ESF) systems allow individual feeding in group settings, reducing competition
Body condition scoring is more challenging in groups - individual monitoring requires more effort
Research shows properly managed group systems improve sow welfare and longevity significantly

Welfare Considerations

Individual gestation stalls prevent sows from turning around, lying down comfortably, or engaging in social behavior for months. Group housing restores these basic behavioral freedoms. However, the welfare benefit is only realized with appropriate space, feeding management, social group stability, and enrichment. Poorly managed group systems can be worse than stalls. The transition requires investment in training, infrastructure, and management skills.
