Disappearance kinetics: A fraction, immediately soluble; B fraction, fractional disappearance rate; C fraction, undegradable; ED, effective degradability; Kd, disappearance rate (Orskov and McDonald, 1979).
Incubation animal diet: Non-supplemented, received no supplemental DDG cubes during in situ incubation period; Supplemented, received 0.90 kg DDG cubes per d during in situ incubation period.
Least-squares means followed by different superscripts differ within rows (P < 0.05).
