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