Outdoor Pig Farrowing Welfare | Animal Welfare Hub

How outdoor farrowing systems compare to indoor alternatives for sow and piglet welfare.

Key Facts

Outdoor pig systems allow sows to farrow in huts on pasture with space to move, root, and express nesting behavior
Nesting behavior is highly motivated in sows — deprivation causes significant pre-farrowing frustration
Piglet crushing risk in outdoor systems is lower than in indoor stalls due to greater sow movement capacity
Outdoor systems are sensitive to weather, requiring appropriate shelter and management in extreme conditions
Certified outdoor pig production represents a premium market segment with documented welfare advantages
Pasture rotation is essential in outdoor pig systems to prevent land degradation and maintain hygiene

Welfare Considerations

Outdoor farrowing systems represent one of the most significant welfare improvements achievable in pig production. Sows are highly motivated to nest before farrowing and experience considerable distress when prevented from doing so in indoor stall systems. Outdoor huts on pasture allow sows to root, gather nesting material, and choose the site of farrowing — fulfilling behavioral drives that are completely suppressed in confinement systems. The welfare benefits are substantial and well-documented. Appropriate management of outdoor systems is essential to translate these benefits into consistent welfare outcomes regardless of weather and season.
