Experimental diets were offered for 108 d. Within rows, values with different superscript differ (P ≤ 0.10).
aL* = lightness index (0 = black and 100 = white); a* = intensity of red color, an index that ranges from green (−) to red (+); b* = intensity of yellow color, an index ranging from blue (−) to yellow (+; Houben et al., 2000)
bWBSF = Warner–Bratzler Shear Force.
