Abstract
The re-grouping of sows at weaning or after service is a common procedure in pig production systems and is one which can have adverse consequences for both welfare and production. One possibility for overcoming the problem is to return sows to previous groups in which a stable social structure was allowed to develop (Arey and Jamieson, 1996). This would utilise the reportedly well developed abilities of the pig to remember other individuals (Ewbank and Meese, 1971). The aim of this experiment was to determine the effect of time between removal and regrouping on social recognition in sows.
