Abstract:

The study was aimed to investigate the effect of Lactobacillus plantarum and Lactobacillus buchneri on the quality and aerobic stability of sugarcane tops silage.There were 10 groups in this experiment:Group A served as control group and no additives;The sugarcane tops silage in groups B,C,D were treated with Lactobacillus plantarum with 10,20,30 mL/kg, respectively;The sugarcane tops silage in groups E,F,G were treated with Lactobacillus buchneri with 10,20,30 mL/kg, respectively;The sugarcane tops silage in group H,I,J were treated with Lactobacillus plantarum+Lactobacillus buchneri (1:1) with 10,20,30 mL/kg, respectively.There were 3 replicates in each group,and the sugarcane tops was stored at room temperature for 40 d,and the quality and aerobic stability of silage were determined.The results showed that:Compare to control group,the pH was significantly reduced and lactic acid concentration was increased of sugarcane tops silage in Lactobacillus plantarum adding groups (P<0.05),and with the increase of Lactobacillus plantarum,the concentration of lactic acid increased.Compare to Lactobacillus plantarum adding groups,the concentration of lactic acid of Lactobacillus buchneri adding groups was significantly decreased (P<0.05),while the acetic acid content was significantly increased (P<0.05),and the effect was more obvious with the increase of Lactobacillus buchneri adding dose,and the aerobic stability was increased by 48 h compared with the control group.The concentration of lactic acid of Lactobacillus plantarum and Lactobacillus buchneri adding groups were significantly increased (P<0.05),and the DM losses was reduced and WSC utilization efficiency was improved compare to Lactobacillus buchneri adding groups.In conclusion,Lactobacillus plantarum and Lactobacillus buchneri adding together (2×106 CFU/g FW) could improve the quality and aerobic stability of sugarcane tops silage.

Key words: sugarcane tops silage; Lactobacillus plantarum; Lactobacillus buchneri; silage quality; aerobic stability
