| 摘 要： | 为提高臂形草青贮品质,对材料切短与否和添加物(无添加-W、乳酸菌1-LAB1、乳酸菌2-LAB2、5%麦麸-F)的影响进行了研究。结果表明,仅凭切短对臂形草青贮料的pH值没有显著影响,但降低了乙酸、丙酸和丁酸等挥发性脂肪酸的含量。切短增加了NH3-N含量,添加乳酸菌可使之显著减少(P<0.05)。乳酸菌和麦麸添加对切短与未切短的材料,在降低pH值和增加乳酸含量方面效果都很明显,特别是切短臂形草接种LAB2的效果最佳。切短组臂形草青贮开封后,有氧稳定性高低顺序依次为W>LAB1>F>LAB2。

| Abstract: | The effects of chopping and additives(lactic acid bacteria-LAB1,lactic acid bacteria preparation-LAB2,5% wheat bran-F) on the fermentation quality of Brachiaria decumbens cv.Reyan No.3 silage were investigated.The results showed that chopping treatment alone did not affect pH values(P>0.05),although it reduced acetic acid,propionic acid,and butyric acid contents.NH3-N content was increased by chopping treatment alone but was significantly reduced by adding lactic acid bacteria(P<0.05).The addition of lactic... |
