Note. Values with different letters in the same row differ significantly; the lowercase letters show the level of 0.05; the capital letters show the level of 0.01. LW, live weight; CW, carcass weight; SEP, semieviscerated percentage; EP, eviscerated percentage; BMW, breast muscle weight; BMP, breast muscle percentage; LMW, leg muscle weight; LMP, leg muscle percentage; AFW, abdominal fat weight; AFP, abdominal fat percentage; SFT, skin fat thickness; SF, shear force; WRD, water depletion rate.
