The study investigated (1) if feed-restriction during rearing affects behaviour towards females at sexual maturity and (2) if aggressiveness towards females is correlated with general levels of aggressiveness. The study compared broiler breeder males with commercial laying strain males, which were either fed ad libitum or were feed-restricted during the rearing phase, and with game strain males, bred for fighting. Laying strain males did not behave aggressively towards females, whether feed-restricted or fed ad libitum. Game strain males also were not aggressive towards females. Broiler breeder males displayed higher levels of aggression towards females than did feed-restricted laying strain males. Females struggled more frequently during mating attempts by broiler breeder males and interfered frequently when these males attempted to mate with other females. The results of this study indicate that aggression towards females appears to be a unique problem occurring in broiler breeder male strains and not a function of feed-restriction.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The present experiment was conducted as part of larger study investigating problems of aggression towards females by male broiler breeder fowl.
