The environment into which piglets are weaned significantly affects their welfare; familiar bedding, small group sizes, and minimised mixing reduce weaning stress indicators.
The weaning environment is the first major welfare test a piglet faces outside the farrowing environment. Multiple stressors converge simultaneously: separation from the sow, unfamiliar housing, new diet, and unfamiliar conspecifics. Management strategies that reduce each of these stressors individually have measurable welfare and production benefits. Even simple interventions — familiar bedding, small group sizes, pre-weaning creep access — cumulatively reduce the welfare cost of an unavoidably challenging transition.
