Outdoor pig farming provides more natural conditions than indoor systems but introduces specific welfare risks from weather, predators, and disease. Understanding the full welfare picture helps producers optimize outcomes.
Outdoor pig production offers genuine welfare advantages over indoor intensive systems: pigs can root, forage, engage in natural social behavior, and express species-typical locomotion. However, outdoor systems are not automatically high-welfare environments. Sunburn in fair-skinned pigs during hot summers causes significant pain; inadequate shade or muddy wallowing areas fail to prevent it. Cold and wet conditions without adequate dry shelter cause hypothermia in newborn piglets. The interaction between stockperson skill and the variable outdoor environment is critical: good outdoor pig welfare requires attentive, experienced management that responds to weather conditions. Well-managed outdoor systems consistently outperform indoor systems on multiple welfare measures; the challenge is ensuring management quality keeps pace with the inherent variability of outdoor production.
