Two diets, identical in the concentration of ileal digestible lysine, methionine, threonine and tryptophan but differing in the crude protein content (18 or 15.1%) were fed ad libitum to 16 Pietrain and line 990 pigs. Protein and energy balance were measured by a comparative slaughter method from 25 to 70 kg body weight. Pietrain pigs consumed 0.33 kg less feed daily, gained 195 g less per day, and had poorer feed utilization by 0.23 kg daily than counterparts from line 990.
