SEM, standard error of the mean; n = 3.

¹Parameter were calculated by P = a + b(1-e^−ct). P = dry matter disappearance at time (g∙kg⁻¹ DM); a = rapidly soluble fraction (g∙kg⁻¹ DM); b = insoluble potentially degradable fraction (g∙kg⁻¹ DM); c = constant rate of disappearance for b fraction (g∙kg⁻¹ DM)h⁻¹; and t = fermentation h in the rumen.

²Values were calculated by ERD = a + b(c/(c + p)). p = ruminal passage rate 40(g∙kg⁻¹ DM)h⁻¹.

^a,bMeans in a row followed by different superscript letters are significantly different (P < 0.0001).
