Means with different letter within each row differ (p < 0.05).
TDN, total digestible nutrients. For proso millet and sorghum-sudangrass hybrid, TDN was calculated according to the following equation: [889 - (0.79 × ADF, g/kg DM)]. For corn plant, TDN was claculated using the following equation: [878.4 - (0.70 × ADF, g/kg DM)] [46]; RFV, relative feed value calculated according to the following equation: [(dry matter intake × digestible dry matter)/1.29], where dry matter intake = 120/(NDF%) and digestible dry matter = 88.9 - (0.779 × ADF%) [47].
