Outdoor pig production provides welfare benefits through natural behaviour expression but also presents specific challenges. Understanding what makes outdoor systems genuinely welfare positive helps consumers and producers make better choices.
Outdoor pig production, at its best, provides welfare significantly superior to indoor systems through access to natural substrate, space for movement, and social complexity. Pigs rooting in soil, wallowing in mud, and foraging across varied terrain express species-typical behaviours that indoor systems deny. However, outdoor systems are not uniformly good welfare - poorly managed outdoor systems with inadequate shelter, overstocked land, or inadequate water provision can cause different but equally serious welfare problems. The welfare quality of outdoor production depends critically on management standards, stocking rates, and seasonal management of heat and cold stress.
