Outdoor pig production systems provide natural behaviour expression and welfare benefits that intensive indoor systems cannot match, but they introduce their own management challenges.
Outdoor pig production at its best provides animals with a quality of life that indoor systems fundamentally cannot replicate — natural behaviour expression, social complexity, environmental stimulation, and fresh air throughout their lives. The welfare benefits are real and measurable. However, poorly managed outdoor systems can expose pigs to welfare risks from extremes of weather, inadequate shelter, and infectious disease. Quality of management determines welfare outcomes in outdoor as much as indoor systems.
