Farmed Pig Housing Transition Stress

The welfare impacts of moving pigs between housing systems at different life stages and strategies to minimize transition stress.

Key Facts

Moving pigs to new housing causes acute stress from novel environment and social disruption
Weaning, moving to grower housing, and fattening unit moves are key transition points
Familiar bedding and objects from previous housing reduce novelty stress in new environments
Keeping social groups intact during housing transitions significantly reduces aggression
Acclimatization periods before full production exposure reduce transition stress

Welfare Considerations

Housing transitions expose pigs to multiple simultaneous stressors including novelty, social disruption, and unfamiliar environmental conditions. Each transition is a preventable welfare cost that can be reduced through thoughtful management of the transition process.
