Pig Welfare Open Air Systems

Open air pig systems provide welfare benefits through outdoor access, natural behaviors, and environmental complexity beyond indoor alternatives.

Key Facts

Outdoor pigs show significantly lower levels of tail biting than indoor housed pigs
Rooting in soil and foraging for natural foods provides behavioral enrichment unavailable indoors
Outdoor pigs have lower cortisol levels and better immune function in multiple studies
Seasonal management challenges including heat in summer and mud in winter require active welfare management
Higher land use and disease risk management requirements make outdoor systems more complex to manage

Welfare Considerations

Outdoor pigs able to root, forage, wallow in mud, and experience natural environments experience substantially better welfare than those in intensive indoor systems. Challenges including seasonal extremes require proactive management to realize welfare benefits.

What You Can Do

Choose outdoor-raised pork from certified sources when available
Support farms transitioning from indoor to outdoor systems through consumer choice
Advocate for agri-environment subsidies that support outdoor pig systems on appropriate land
