Abstract：The sensory,nutritional value and fermentation quality of the mixed storage of Indigofera amblyantha Craib and Paspalum wettsteinii were evaluated by eight additive treatments,and the best additive treatment was selected.Using a completely randomized experimental design,an equal amount of water(65 mL)was designed as the control(T1),other treatments included 1 g/kg cellulase(T2),0.03 g/kg silage fermentation agent(T3),30 g/kg glucose(T4),0.5 g/kg cellulase + 0.015 g/kg silage fermentation agent(T5),0.5 g/kg cellulase + 15 g/kg glucose(T6),0.015 g/kg silage fermentation agent + 15 g/kg glucose(T7)and 0.5 g/kg cellulase + 0.015 g/kg silage starter + 15 g/kg glucose(T8),with three repetitions per treatment.The results showed that all the eight treatments of Indigofera amblyantha Craib and Paspalum wettsteinii Hack mixed silage resulted in best silage quality scores,with a grade Ⅰ level for sensory evaluation.Silage additives can improve the mixed silages'nutritional value and their fermentation quality.The result of grey correlation analysis was as follows:T4＞T6＞T7＞T8＞T5＞T2＞T3＞T1,indicating that the addition of glucose in mixed silage could gave the best silage quality.The study indicates that silage with 30 g/kg of glucose,or silage with 0.5 g/kg of cellulase + 15 g/kg of glucose,can result in the best silage quality,which are considered to be the optimal additive for Indigofera amblyantha Craib and Paspalum wettsteinii Hack mixed silage.
