Large White pigs from lines which had been divergently selected over 4 years for high and for low post-weaning daily gain on a fixed but restricted ration of approximately 80% of ad libitum, were sampled for growth testing on ad libitum individual feeding during a 6-week period starting at 50 kg. It is concluded that selection for high growth rate on restricted feeding will produce pigs which perform more profitably on ad libitum individual feeding.
