Outdoor pig systems offer significant welfare advantages over intensive indoor systems, but present distinct management challenges including predation, environmental extremes, and variable husbandry quality.
Outdoor pig welfare is genuinely better on multiple dimensions compared to intensive indoor systems, but the 'outdoor = automatically good welfare' equation is too simple. A poorly managed outdoor system can expose pigs to extreme weather without adequate shelter, inadequate nutrition when foraging opportunities are depleted, predation stress from digging underneath fence lines, and fly strike in summer without regular monitoring. The soil-based rooting behavior that is so important for pig welfare also creates landscapes that become churned mud in wet conditions, increasing limb injury and reducing the behavioral value of outdoor access. Management quality varies enormously between outdoor producers. Certification schemes for outdoor systems should specify shelter adequacy, stocking density, and monitoring requirements rather than certifying 'outdoor' as a uniform welfare standard. Consumer understanding that 'outdoor-reared' encompasses a range from excellent to poor welfare is important for informed purchasing.
