Data are least squares means of 8 observations for all diets.
1Quad = quadratic effect.
2ELW = ending live weight.
3Standardized fat free lean = {[8.588 + (0.465 × HCW, lb) – (21.896 × 10th-rib fat depth, in) + (3.005 × 10th-rib LMA, in2)] / HCW × 100 (Burson and Berg, 2001).
4L* = measure of lightness (greater value indicates a lighter color), a* = measure of redness (greater value indicates a redder color), and b* = measure of yellowness (greater value indicates a more yellow color).
