This study investigated the effect of novel Lactobacillus plantarum KCC-10 and KCC-19 on the quality and fermentation characterization of alfalfa silage at the experimental field of National Institute of Animal Science, Cheonan Province, Korea, from 2013 to 2014, and this experiment consisted of the following three treatments: control without lactic acid bacteria; treatment inoculated with L. plantarum KCC-10; and treatment inoculated with L. plantarum KCC-19. The contents of crude protein, acid detergent fiber, neutral detergent fiber, total digestible nutrient and in vitro dry matter digestibility of alfalfa silage were not affected by either L. plantarum KCC-10 or KCC-19. The pH of alfalfa silage in L. plantarum KCC-10 and KCC-19 treatments decreased as compared to control. The level of lactic acid in L. plantarum KCC-10 and KCC-19 treatments increased (p0.05), whereas the contents of acetic acid and butyric acid decreased(p0.05). In addition, the numbers of lactic acid bacteria in L. plantarum KCC-10 and KCC-19 treatments increased as compared to control (p0.05). Therefore, these results suggest that the inoculation of L. plantarum KCC-10 and KCC-19 into alfalfa silage can improve the quality of silage through increased lactic acid content and lactic acid bacteria.
