Extract

The feeding behaviour of group-housed pigs differs from that of pigs housed individually in that they make fewer visits to the feeder of a longer duration (Bornett et al., 2000). Possible reasons for this difference in feeding behaviour include competition and group cohesion and these may be influenced by group composition in terms of aggressiveness. Indeed, Erhard et al. (1997) found that groups comprising all low aggressive pigs integrated into a group quicker than groups of all high aggressive pigs. The aim of this study was to investigate the effect of aggressiveness of individuals on the feeding behaviour of group-housed growing pigs.
