Free Range and Outdoor Pig Welfare

Outdoor pig production allows pigs to express a wider range of natural behaviours but presents specific welfare challenges.

Key Facts

Outdoor-bred pigs spend part of their lives outdoors but are typically finished indoors
Free-range and outdoor pigs have access to rooting, wallowing, and natural substrate
Sun exposure causes heat stress and sunburn in pigs without wallowing opportunities
Outdoor systems have welfare benefits for sows but piglet mortality can be higher
UK outdoor pig production represents approximately 40% of breeding sow herd management

Welfare Considerations

Outdoor pig production provides genuine welfare benefits — sows can perform nest-building before farrowing, piglets can explore and play in natural environments, and rooting behaviour can be expressed in real substrate. However, outdoor systems have welfare challenges including heat stress in summer, cold and wet conditions in winter, and higher piglet mortality from crushing and exposure. Good outdoor systems manage these risks through adequate shade, shelter, and careful monitoring, delivering genuine welfare improvements over indoor systems.
