The aim of this study was to improve computerized restricted feeding systems for growing pigs taking into account feeding behaviour and aggression in groups. The study was carried out on 48 Large White pigs, castrated males and females in 4 groups of 12 pigs. Feed was supplied ad libitum (one group) or restricted (80% of ad libitum, three groups). Individual social rank was determined at the beginning of the experiment and feeding behaviour was examined between 60 and 90 kg liveweight.
