The focus of this study was to determine the effects that a communal piglet area had on pre- and post-weaning behaviour and performance of piglets. Three litters were combined to from a cohort, with 10 experimental and 10 control cohorts examined. In the experimental treatment, two central crates were left empty and became the communal area, which consisted of six creep feeders, a covered area, and PVC pipe and cotton rope for enrichment. The controls left the two central crates empty, but the litters remained isolated from one another. The piglets were allowed access to the communal area from11 days of age until they were weaned at 28 days of age. At weaning, the cohorts either remained unmixed or three piglets were mixed with another three piglets from different cohort. Throughout the study, piglets and feeders were weighed, as well as, video recordings were taken to document various behaviours before and after weaning. Experimental pigs, when compared to the controls, spent considerably more time away from the sow, which resulted in a reduced nursing frequency. This reduction did not coincide with a significant increase in creep feed intake, however the experimental piglets ate 86% more creep feed than control piglets. There was not a difference in weight gain between experimental or control piglets prior to weaning. Aggression was minimal when the piglets were allowed access to the communal area, as well; cross-suckling aggression from the sows was also rare. A reduced amount of aggression was also seen weaning. After weaning, the experimental piglets ate more and tended to gain more weight than the control piglets. Piglets that were mixed at weaning ate less feed and had lower weight gains than cohorts that remained intact.
