Pig Welfare and Welfare and Housing Transition Stress

Housing transitions between production stages cause significant welfare stress in pigs, with management strategies available to minimise harm.

Key Facts

Moving pigs between housing environments causes acute stress lasting 24-72 hours
Social mixing at transitions combines environmental and social stress, amplifying welfare harm
Maintaining stable social groups across transitions reduces stress significantly
Familiar bedding or odour transfer provides olfactory cues that reduce novelty stress
Gradual environment changes within housing periods reduce adaptation stress

Welfare Considerations

Housing transition stress is a significant, manageable welfare problem. Management strategies that reduce mixing and maintain familiarity prevent considerable suffering.
