¹ HCW—hot carcass weight; HCY—hot carcass yield; CCW—cold carcass weight; CCY—cold carcass yield; CY—carcass yield; CCWL—chilling carcass weight loss; OCL—outer carcass length; ICL—inner carcass length; CG—chest girth; CD—chest depth; HLW—hind limb width; HG—hind limb girth; LW—leg width; LL—pelvic limb length; CCI—carcass compactness index; LCI—leg compactness index; FT—fat thickness; RA—ribeye area; ² MSE—mean square error; ³ P values from treatment (Treat) and orthogonal contrast (linear and quadratic) are significantly different if p ≤ 0.05 and are a tendency if 0.05 < p < 0.10.
