The invention discloses an application of
lactococcus lactis KDLL2016-01 in preparation of a
protein feed by fermenting feathers, which belongs to the technical field of
animal nutrition and a feed. The application comprises the following steps: crushing feathers into
feather meal, sterilizing and adding the material into a
fermentation culture medium; inoculating the
lactococcus lactis KDLL2016-01 into a
fermentation culture medium, and carrying out
fermentation culture; and after the fermentation is finished,
drying a fermentation product to obtain the
protein feed. According to the application, the adopted
lactococcus lactis KDLL2016-01 does not generate harmful metabolites in a culture process, the product can be directly fed to
livestock and poultry without detoxification and other treatment on the fermented product, and lactococcus
peptide generated in the fermentation process can also kill
pathogenic bacteria possibly existing in the feed, so that the quality of the feed is
safer. The
protein feed prepared by the method is suitable for feeding
livestock and poultry.
