1)

Ground, ground corn; Flake_(% gelatinization).

2)

A, soluble fraction (% DM); B, slowly degradable fraction (% DM); kd, fractional rate of degradation (h−1).

3)

Effective ruminal degradability when fractional rate of passage is 0.04 h−1, 0.06 h−1, and 0.08 h−1, respectively.

a,b

Means that do not have common superscript differ (p < 0.05).

DM, dry matter.
