Abstract: The assay was aimed to investigate the effect of different microbial inoculant combinations of Candida tropicalis (CT),Bacillus subtilis (BS),Lactobacillus plantarum (LAP) and Lactobacillus buchneri (LAB) on the quality and aerobic stability of sugarcane tops silage.There were 10 groups:Sugarcane tops silages with no additives served as control group (C);GroupsⅠ1,Ⅰ2 and Ⅰ3 were treated with CT+BS at 10,20 and 30 mL/kg,respectively;Groups Ⅱ1,Ⅱ2 and Ⅱ3 were treated with CT+BS+LAP at 10,20 and 30 mL/kg,respectively;Groups Ⅲ1,Ⅲ2 and Ⅲ3 were treated with CT+BS+LAB at 10,20 and 30 mL/kg,respectively.Each treatment was treated with 0.5% fresh forge urea.The results showed that:①Compared to control group,CT+BS treatment groups had significantly higher levels of pH and acetic acid (P< 0.05),dry matter recovery (DMR) and lactic acid content were significantly decreased (P< 0.05),and the aerobic stability was lower.②Compared to control group,CT+BS+LAP treatment groups had significantly higher levels of pH and lactic acid (P< 0.05),and the aerobic stability was lower.③In CT+BS+LAB treatment groups,the levels of acetic acid were significantly higher and DMR was significantly lower than control group (P< 0.05),and the CP content and aerobic stability were highest in all groups.So the quality of sugarcane tops silage was lower in CT+BS treatment groups and CT+BS+LAB treatment could improve the quality and aerobic stability of sugarcane tops silage.

Key words: sugarcane tops silage; microbial inoculant; silage quality; aerobic stability
