Indoor Pig Welfare Standards: Current Evidence

Evidence-based welfare standards for indoor pigs specify the conditions needed to meet key welfare needs in confined systems.

Key Facts

Indoor pigs require manipulable materials to prevent tail biting regardless of system
EU and UK regulations specify minimum environmental temperatures for weaner pigs
Space allowances in welfare codes are based on minimum needs rather than optimal welfare
Written health plans are required in pig assurance schemes to address common welfare risks
Unannounced welfare audits in pig units improve compliance with welfare requirements

Welfare Considerations

Evidence-based welfare standards for indoor pig systems provide specific requirements grounded in scientific understanding of pig behavioural and physiological needs. Standards addressing enrichment, space, temperature, and social management reflect the minimum conditions needed to prevent the worst welfare outcomes. Exceeding minimum standards through investment in higher welfare systems delivers greater benefits for pig welfare.
