Play behaviour (substrate play, rolling, pivoting, gambolling), manipulative behaviour (nibbling, sucking or chewing part of the body of another piglet) and belly nosing (rubbing belly of pen mate with up and down movements of the snout) in the first 2 weeks postweaning of piglets that switched environments (barren preweaning to enriched postweaning, or enriched preweaning to barren postweaning) at weaning, and that were housed together with a confined (limited opportunities for interaction) or loose-housed sow (increased opportunities for interaction) before weaning.
