  1. 1BW = body weight; SD = shank diameter at 63 d of age; ADG = average daily gain. 2 Numbers in bracket referred to sample size for each genotype. a,b Means within a row with no common superscript differ significantly (P < 0.05). A,B Means within a row with no common superscript differ highly significantly (P < 0.01).
