Abstract: This study aimed to prove up the effects of fermented green juice and xylanase on quality of rice straw silage.A control group (CON) and three treatment groups which added 2 mL/kg fermented green juice (FGJ),20 mg/kg xylanase (XYL),compound them (2 mL/kg FGJ+20 mg/kg XYL,MIX) respectively and were both set up with conventional moisture (MC1) and low moisture (MC2) of rice straw silage.Each treatment was repeated 3 times.The materials were ensiled at room temperature and opened 60 days later.The results showed that in the MC1 silages,compared with the CON group,the contents of moisture and ADF in the MIX group were significantly decreased (P<0.05),the content of AN in the FGJ、XYL and MIX groups was extremely significantly decreased (P<0.01),the content of WSC in the FGJ、XYL and MIX groups was significantly or extremely significantly increased (P<0.05;P<0.01),the content of NDF in the XYL and MIX groups was significantly decreased (P<0.05),the pH in the FGJ group was extremely significantly decreased (P<0.01).In the MC2 silages,compared with the CON group,the content of moisture in the FGJ group was significantly decreased (P<0.05),the content of WSC and DMR in the FGJ group were significantly increased (P<0.05),the contents of AN and NDF in the FGJ and MIX groups were significantly or extremely significantly decreased (P<0.05;P<0.01),the pH in the FGJ,XYL and MIX groups was extremely significantly decreased (P<0.01),the content of ADF in the MIX group was significantly decreased (P<0.05).Compared with the MC1,the pH and DMR in the MC2 were extremely significantly increased (P<0.01),the content of WSC in the MC2 was significantly increased (P<0.05),the content of AN was extremely significantly decreased (P<0.01).In conclusion,three additive had significant effect in the MC1 silages and MC2 silages,especially the effect of the mixed addition of FGJ and XYL was the best,and the MC2 silages had higher quality than the MC1 silages.
