1 CONT = control; EML = ensiled mulberry leaves; SMFP = sun-dried mulberry fruit pomace.
2 LMA = LM area measured at 12th rib.
3 Fat color measurements obtained approximately 20 cm ventrally to the lateral process of the split carcass adjacent the 13th rib.
4 CIE color measurements: L* = lightness, black (0) to white (100); positive a* = red; negative a* = green; positive b* = yellow; negative b* = blue; c* = color saturation = [(a*)2 + (b*)2]1/2 whereby a large number is considered to be more vivid.
