Outdoor access and rooting opportunities represent the gold standard for pig welfare, allowing the full expression of natural behaviors impossible in conventional intensive housing.
The contrast between outdoor and intensive indoor pig welfare is stark. Pigs in outdoor systems can root continuously in soil, wallow to cool themselves, choose their social interactions, forage for variety in their diet, and exercise normal ranging behavior. These activities are not luxuries but expressions of species-typical behaviors strongly motivated in all pigs. Indoor pigs denied these behaviors live in an environment of enforced behavioral restriction. The welfare case for outdoor pig production is strong, even considering the management challenges. Consumer demand for outdoor-reared pork creates the market signals that make outdoor production commercially viable for more producers.
