Actual research and application of the silage lactic acid bacteria additives

The addition of lactic acid bacteria (LAB) plays an significant role in improving the quality of silage. In this paper, in order to define the research and application of LAB additives globally, the fermentation characteristics of LAB in silage and the study on screening and application is summarized. At present, the research has clarified the fermentation principle and the fermentation phases. The research include several aspects, as follows: firstly, the three factors impacting fermentation comprise LAB itself, environmental factors, and crop characteristics; secondly, studies on LAB addition to silage mainly concentrated on screening and adding the most suitable LAB to ensile; thirdly, application methods of LAB to silage mainly include adding individually and mixed, with enzymes or other functional microbes. In future studies, LAB should been explored and screened from various ecological environments, and the research of utilization technology according to actual demand and agricultural technology of China should be strengthened.
