Outdoor and free-range pig production systems provide substantially better welfare than intensive indoor systems, though they face economic and environmental trade-offs.
Outdoor pig production represents the most accessible high-welfare alternative for pigs in most temperate climates. Outdoor pigs can root, wallow in summer, establish natural social hierarchies, and express the full behavioral repertoire that indoor systems restrict. The welfare improvement over conventional indoor systems is substantial and well-documented. Economic challenges including higher land requirements and predation risk, and environmental trade-offs around land use and nutrient management, are real but manageable. Consumer willingness to pay premiums for outdoor pork products is essential to the commercial viability of systems that deliver dramatically better animal welfare.
