摘要
[Objective] To provide a reference for scientific and rational utilization of forage silage. [Method] The number and species of microorganisms in forage were analyzed, and the characteristics of 11 strains of lactic acid bacteria （LAB） were studied. [ Result] All the isolates were Gram-positive, catalase negative and aeroanaerobic. The isolated strains of homofermentation accounted for 78%. The isolates were divided into three groups, Lactobacillus, Leuconostocaceae and Lactococcus, according to their morphological and biochemical characters. [ Conclusion] The microorganisms in forage in northwest China were isolated and identified, which provides a scientific basis for utilization of forage silage.
