  1. 1GE gross energy, AME apparent metabolizable energy, TME true metabolizble energy, NDF Neutral detergent fiber, ADF acid detergent fiber, CP crude protein, L*, a*, and b* are measures of degree of lightness, redness, and yellowness, respectively.
  2. 2Values within a row with * means P < 0.05, ** means P < 0.01.
