### Energy and In Vitro Digestibility of Amaranth and Wheat Bran Mixed Silage
In the same L, E and M groups, GE was lower in the 60% MC group than in the 70% MC group, and NEf, IVMD, IVOMD, and IVCPD were higher in the 60% MC group than in the 70% MC group (\(p<0.05\)). Under 60% MC, the NEf of AWB mixed silage was higher in the E group than in the control group, the IVCPD and IVNDFD of AWB mixed silage were higher in the E and M groups than in the control group, and the GE, DE, ME, NEm, and NEI of AWB mixed silage were higher in the L, E, and M groups than in the control group (\(p<0.05\)). \begin{table}
