Abstract:This study aimed to investigate the effects ofco-adding Lactiplantibacilus plantarum and celulase on the fermentation quality of mulberry (Morus alba)leaf silage and to provide a basis for the feed utilization of mulberry leaf resources. The experiment comprised three treatments: the CK group (no additives),the SL group added with L .plantarum (5×105CFU⋅g-1FM) ,and the SLC group added with L. plantarum (5×105 (204号 CFU·g-1 FM)and cellulase (0.3% FM). Each group had six replicates. After 6O days of fermentation,we analyzed sensory indicators,nutritional components,fermentation quality,and the number of major microorganisms.The gas production characteristics were evaluated by an in vitro fermentation test. The results showed that compared with the CK group,the contents of dry mater,crude protein,water-soluble carbohydrates, lactic acid,acetic acid,and the number of lactic acid bacteria in the SLC group showed significant increases ( ⋅P<0.05) ,while the contents of neutral detergent fiber,acid detergent fiber, pH value,the number of yeast, mold,and aerobic bacteria decreased (P<0.05) .Compared with the CK group,the organic matter degradation rate,gas production,and gas production rate of the SLC group increased ( .P<0.05 .It is evident that the co-addition of L . plantarum and celllase can significantly improve the fermentation quality of mulberry leaf silage,reduce nutrient loss,and enhance the feeding value.
