a = Readily soluble fraction, b = Insoluble but potentially degradable fraction, c = Constant rate of degradation of b (%/h).

ED = Effective degradability. Rumen passage rate (k) was considered to 0.05.

SEM means standard error for means.

^a,b,c,d,e

Indicates that the means are significantly different within different feeds (p<0.05).
