植物乳杆菌和布氏乳杆菌对甘蔗尾青贮品质的影响
Effects of Lactobacillus plantarum and Lactobacillus buchneri on the Quality of Sugarcane Tops Silage
摘要
Abstract
This experiment was aimed to explore the effects of Lactobacillus plantarum(LAP)and L actobacillus 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.T he experimental groups were set up as follows,Group Ⅰ:20 mL of LAP(6.00×1010CFU/mL)and 30 mL of normal saline;Group Ⅱ:20 mL of LAB(8.80×109CFU/mL)and 30 mL of normal sa-line.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 sta-bility 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 con-trol group had higher content of butyric acid,while no butyric acid was detected in two experi-mental 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 com-pared with control group(P< 0.05).Conclusively,addition of LAP or LAB significantly im-proved the quality and aerobic stability of sugarcane tops silage,while LAP was better.关键词
