Method for preparing Enterococcus faecalis fermented mixed feed for birds

Abstract

The invention discloses a method for preparing a poultry enterococcus faecalis mixed feed. The preparation method comprises steps that (1) MRS culture medium is used for culturing FQ15 enterococcus faecalis to become a first level seed; (2) enlargement cultivation is carried out in a starter can; MRS culture medium is adopted as a culture medium to culture the first level seed so and the first level seed becomes a second level seed; (3)fermentation cultivation is carried out in a fermentor; MRS culture medium is adopted as a fermentation culture medium to culture the second level seed and the second level seed becomes a third level seed; (4)rice bran, bran, and cut maize are mixed together and well blended with the third level seed liquid, the mixture are fermented and cultured to be prepared into a first fermentation feed; (5)the first fermentation feed, bean cake, bran, fish meal, bone meal, shell power and salt are blended into the poultry enterococcus faecalis mixed feed. The method of the invention can improve the nutritional content of coarse fodder and ensures that plant fiber is transformed to small molecules materials which are easily absorbed by poultry. When the mixed feed is applied to poultry, antibiotics and hormones are not used, the mixed feed can promote the growth of poultry.

Description

technical field [0001] The invention relates to a preparation method of microbial fermented mixed feed, in particular to a preparation method of poultry Enterococcus faecalis fermented mixed feed. Background technique [0002] For the feed used in poultry breeding, on the one hand, it is necessary to consider the nutrients in the feed to improve the cost performance of the feed, and on the other hand, it is also necessary to consider whether the feed itself can improve the resistance of the poultry to pathogenic microorganisms. Ordinary feeds are often added with "three elements". That is: antibiotics, hormones and vitamins, but the abuse of "three elements" will affect the quality of poultry meat and eggs as human food, causing potential harm to humans. Therefore, there is an urgent need for a nutritional labeling that can improve roughage , so that the plant fiber can be converted into a feed with small molecules that poultry can easily absorb and can improve the resistanc...
