The invention discloses a
sturgeon pathogenic bacterium inhibitor and belongs to the technical field of
sturgeon pathogenic breeding. The
sturgeon pathogenic bacterium inhibitor comprises the following raw materials in parts by weight: 43-52 parts of sweet wormwood, 10-16 parts of
oligopeptide fish
dissolution powder, 7-10 parts of
choline chloride, 20-28 parts of
atractylodes macrocephala, 10-20parts of rhizoma polygonati, 30-35 parts of Baijiu, 0.1-0.3 part of EM (
Effective Microorganism)
bacteria, 10-15 parts of beer
yeast and 10-15 parts of a liver protection agent. A preparation method comprises the following steps: I, preparing the raw materials according to the parts by weight; II, baking the sweet wormwood, fumigating and baking the
atractylodes macrocephala and the rhizoma polygonati on the sweet wormwood, crushing into
powder, collecting sweet wormwood ash, and
coating with
choline chloride so as to obtain
chloride granules; III, mixing the beer
yeast with the EM
bacteria, leaving to stand for 3-5 days so as to obtain a bacterial material, and uniformly stirring the
oligopeptide fish
dissolution powder, the
atractylodes macrocephala powder, the rhizoma polygonati powderand the liver protection agent so as to obtain a mixture; IV,
coating the chloride granules with a bacterial material, and further
coating the outermost layer with the mixture, thereby obtaining the sturgeon pathogenic bacterium inhibitor. The sturgeon pathogenic bacterium inhibitor disclosed by the scheme of the invention is capable of remarkably increasing the ratio of beneficial bacterium florae in intestinal tracts of sturgeon pathogenic.
