N = Number of records; minimum = minimum values; maximum = maximum values; LS Mean = least square mean; RSD = residual standard deviation; BW01, BW17, BW40, BW60, BW80, and BW120 are the BW at days 1,17, 40, 60, 80, and 120 of age, respectively; PBM = percentage breast meat at 20 week of age; BrL = breast length at 20 week of age; BrW = breast width at 20 wk of age; PDL = percent drip loss at 20 week of age; pHu = ultimate pH at 20 wk of age; L* = lightness at 20 wk of age; a* = redness at 20 wk of age; b* = yellowness at 20 wk of age; As_{wt }= upper asymptotic weight (estimated growth curve parameter); t_{mid }= inflection point at 50% asymptote (estimated growth curve parameter); scale = constant that is proportional to the overall growth rate (estimated growth curve parameter). ^{1 }= The difference between sexes in the Least square means (LS Means) of the traits. ^{2 }= The difference between the maximum and minimum LS Means of the traits with respect to the week of hatch. *P ≤ 0.05, **P ≤ 0.005, ***P ≤ 0.0005
