Outdoor pig farming provides significant welfare benefits but also presents specific welfare challenges particularly around mud management, shelter, and parasite control.
Outdoor pig systems provide genuine welfare benefits including rooting opportunity, natural foraging behavior, and social interaction in more complex environments than indoor systems. However, welfare in outdoor systems is not guaranteed - poorly managed systems create welfare problems specific to outdoor production. Muddy, churned fields become a lameness risk and respiratory disease risk for piglets born in wet conditions. Adequate shade and wallowing areas are essential in hot weather. Parasite management requires rotational grazing to break worm cycles. The welfare of outdoor pigs depends heavily on stocking density, rotation frequency, and the quality of shelter and bedding provision.
