Selection for lean tissue growth rate in modern genotypes and the continued trend in favour of leaving boars entire may have significantly increased the ideal protein requirements of finishing pigs above the value of 8.6 g/MJ DE recommended by ARC (1981). The aim of this study was to measure differences in performance and carcass quality of genetically improved boars and gilts in response to increases in ideal protein content of the diet.
