Outdoor and free-range pig systems offer significant welfare advantages over indoor confinement but require specific management to maintain those benefits year-round.
Outdoor pig farming, when well-managed, provides genuinely superior welfare compared to conventional indoor systems: pigs can root, explore, wallow, and engage in complex social behaviors in natural environments. However, 'outdoor' status does not automatically guarantee good welfare. Poorly managed outdoor systems with inadequate shelter, overgrazing leading to barren muddy paddocks, and inadequate parasite management may provide worse welfare than well-managed indoor systems. The key welfare determinants in outdoor systems are access to functional natural substrates for rooting, adequate shade and shelter, appropriate group sizes, and effective health monitoring across the range. Consumer understanding of what outdoor labels actually mean is often limited.
