The NDICP and ADICP concentrations of the RSM were lower than the values reported in Maxin et al.

In the present study, only a few indices (CP, NDF, ADF, etc.; Table 1) were analyzed actually and the values, including NDICP, ADICP
, peNDF, degradation rates and intestinal digestion rates, were calculated based on the CNCPS v5.0 Temperate Feeds Library.
