Outdoor access for pigs provides welfare benefits through natural rooting, foraging, and exploration that indoor systems cannot fully replicate.
Outdoor access provides pigs with opportunities for natural rooting, foraging, exploration, and sunlight that indoor housing cannot replicate. Pigs with outdoor access show better welfare indicators including lower stereotypic behavior rates and more natural behavioral repertoires. The welfare benefits of outdoor access are substantial and represent one of the clearest welfare improvements available in pig production.
