Abstract

Data collected in this study showed that pigs weaned at approximately 10 days of age manipulated other pen-mates more frequently, spent more time play/fighting, and had greater average daily gains soon after weaning when compared with pigs weaned at approximately 30 days of age. Pigs from both treatments were reared in the same environment; therefore, differences were not likely related to a lack of immune system activation.
