Weaning is one of the most stressful events in a piglet's life, combining maternal separation with dietary transition and social mixing. Evidence-based management significantly reduces welfare costs.
Weaning stress in piglets is both inevitable and manageable. The simultaneous challenges of maternal separation, social disruption, and dietary transition create a welfare-vulnerable period that can be substantially mitigated through progressive approaches - creep feeding before weaning, maintaining litter groups after weaning, and providing high-quality transition diets. The welfare obligation is not to eliminate weaning, which serves important production and maternal welfare purposes, but to ensure that its management minimizes the cumulative stress of these overlapping transitions. Farms that invest in progressive weaning management achieve better welfare outcomes and typically better production results through reduced post-weaning disease.
