Abstract

The invention relates to a biological veterinary drug for preventing and treating white diarrhea of piglets and a preparation method thereof, and belongs to the technical field of biological veterinary drugs. The biological veterinary drug includes, by weight, 5-10% of a lactic acid bacterium fermentation solution, 10-25% of a Clostridium butyricum fermentation solution and 10-25% of a Bacillus cereus fermentation solution, with the balance being water. The microbe concentrations of the three fermentation solutions are 10<7>-10<9> Cfu/mL. The Bacillus cereus fermentation solution is prepared by adding poplar flower powder into an enlargement culture medium of Bacillus cereus for fermentation culture of the Bacillus cereus, and preparing the Bacillus cereus fermentation solution after the fermentation culture is finished. The drug is characterized by being good in effect, safe, environmentally friendly, and the like. Through adoption of the drug, the number of times of use of chemical antibiotics can be reduced, thus reducing drug resistance of piglets to the chemical antibiotics. The drug is simple in preparation process, low in equipment requirement, low in cost and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of biological veterinary drugs, and in particular relates to a biological veterinary drug for preventing and treating pullorum of piglets and a preparation method thereof. Background technique [0002] Pork is the main indicator of the vegetable basket project to improve the living standards of the people, and it is also an important factor affecting price fluctuations. Among them, the key to the development of the pig industry lies in the piglets. There used to be a saying that "well-raised piglets yield half of the income". Two months after the piglet is born, it is called the piglet period, and pullorum (also belonging to E. coli) is most prone to occur at this time. Piglets suffering from "pullourosis" are thin and small, refuse to eat, have diarrhea at first, and then turn into pullorum, contagious, intestinal mucosa has catarrhal inflammation, mesenteric lymph nodes are mildly swollen, and a few sick ...
