Research on gestation crate alternatives demonstrates that group housing systems can achieve comparable production outcomes while dramatically improving sow welfare.
The transition from gestation crates to group housing demonstrates that welfare improvements and production viability can coexist. Initial concerns about group housing — aggression, unequal feed access, competition injuries — have been addressed through electronic feeding systems and evidence-based management protocols. Countries that banned gestation crates have not experienced the production collapses that opponents predicted. The welfare benefits are significant and well-documented: group-housed sows are healthier, more behaviourally normal, and show fewer signs of psychological distress. Consumer campaigns and retailer commitments are proving effective at accelerating this transition where legislation has not yet required it.
