  1. BW00, 04, 08, 12, 16: body weight at hatch, at 4, 8, 12, and 16 weeks of age; CA16: size of comb area at 16 weeks of age; SRBC00, 07, 14: baseline antibody level, antibody level at 7 and 14 days after primary immunization of sheep red blood cell; SD: standard deviation; the p value corresponds to the significance level of the comparison between L2 and R- lines, for each trait
