Free-range outdoor pig production offers significant welfare advantages over intensive indoor systems.
Pigs with outdoor access can root in soil, wallow in mud to thermoregulate, and range freely — behaviours fundamental to pig welfare. Outdoor systems are not automatically high welfare: overcrowded paddocks, inadequate shelter, and poor ground management can produce welfare problems even with outdoor access. Well-managed outdoor pig production represents a genuine welfare improvement but requires careful management to realise its potential.
