Abstract:

This experiment was aimed to explore the effects of Lactobacillus plantarum (LAP)and Lactobacillus buchneri (LAB) on the quality and aerobic stability of sugarcane tops silage.Fresh sugarcane tops were used as raw material and placed inside an air tight polyethylene bag and stored at room temperature to get ensiled.Three experimental groups were set up,every group comprised 3 repeats and every repeat contained 500 g of dried and crushed sugar cane tops.The experimental groups were set up as follows,Group Ⅰ:20 mL of LAP (6.00×1010 CFU/mL) and 30 mL of normal saline;Group Ⅱ:20 mL of LAB (8.80×109 CFU/mL) and 30 mL of normal saline.The treatment without inoculant and contained only 50 mL of normal saline served as the control group.After 45 days,the nutritional composition,pH,volatile fatty acids and aerobic stability of every group were determined.The results showed that,pH of group I and group Ⅱ were significantly lower compared with those of control group (P<0.05).Lactic acid production in group Ⅰ and acetic acid production in group Ⅱ were significantly increased (P<0.05).The control group had higher content of butyric acid,while no butyric acid was detected in two experimental groups (P<0.05).Ammonia nitrogen content in group Ⅰ was significantly lowered (P<0.05),while crude protein (CP) content was increased (P=0.071) as compared with control group.NDF and ADF contents in group Ⅰ and group Ⅱ were significantly lowered (P<0.05),and aerobic stability was significantly increased by 34.29% and 42.86%,respectively,as compared with control group (P<0.05).Conclusively,addition of LAP or LAB significantly improved the quality and aerobic stability of sugarcane tops silage,while LAP was better.
