BWAFEL = body weight at age at first egg lay; AAFEL = age at first egg lay; WLH = White leghorn; EWFEL = egg weight at first egg lay; SL = significance level.

^a,b,c,d

Means within a row with different lowercase letters are significantly different. W0, 4, 8, 12, 16, 20 = body weight at hatch at 4, 8, 12, 16, and 20 weeks of age; BWG 0–4, 4–8, 8–12, 12–16, and 16–20 = body weight gain from 0 to 4, 4 to 8, 8 to 12, 12 to 16, and 16 to 20 weeks; FI 0–4, 4–8, 8–12, 12–16, and 16–20 = feed intake from 0 to 4, 4 to 8, 8 to 12, 12 to 16, and 16 to 20 weeks; FCR 0–4, 4–8, 8–12, 12–16, and 16–20 = feed conversion ratio at 0–4, 4–8, 8–12, 12–16, and 16–20 weeks.
