Pig Rearing System Comparison and Welfare Outcomes

Comparing pig rearing systems reveals welfare trade-offs that inform consumer choice and policy decisions.

Key Facts

Fully indoor systems offer disease control advantages but limit natural behaviour
Outdoor systems allow rooting and natural behaviour but have higher parasite exposure
Deep litter systems provide enrichment opportunities at lower cost than outdoor access
Welfare quality assessments compare systems across multiple welfare dimensions
No single system maximises all welfare dimensions simultaneously

Welfare Considerations

Different pig rearing systems involve genuine welfare trade-offs. Consumers and policymakers need to understand that system comparisons are complex - an outdoor system may allow natural behaviour but increase parasite burden, while an indoor enriched system may provide disease control but limit space. Welfare assessment frameworks that evaluate multiple dimensions provide the most honest comparison.
