BW7, BW14, BW21, BW35, BW42, BW49, BW56, BW70, BW77 and BW84 indicated body weight at 7, 14, 21, 35, 42, 49, 56, 70 and 77 days, respectively. SL70 or SL84 = shank length at 70 or 84 days. SD70 = shank diameter at 70 days. ADG2 meant average daily gain from 4 to 8 weeks. CW = chest width. DW = dressed weight. SEW = semi-eviscerated weight. EW = eviscerated weight. BMW = breast muscle weight. AFW = abdominal fat pad weight. Number in brackets meant the number of birds tested for each genotype. The a,b or A,B values with no common superscripts within a column indicated the comparison was differed significantly (P < 0.05 or P < 0.01).
