Poultry and livestock intestinal ecological restoration microbial agent with virus and pathogenic bacteria-resisting functions and antibiotic-replacing effect and preparation method thereof

Abstract

The invention discloses a poultry and livestock intestinal ecological restoration microbial agent with virus and pathogenic bacteria-resisting functions and antibiotic-replacing effect and a preparation method thereof. The poultry and livestock intestinal ecological restoration microbial agent is prepared by mixing saccharomyces cerevisiae, candida utilis, bacillus subtilis, bacillus licheniformis, rhodopseudomonas palustris, lactobacillus plantarum, and lactobacillus rhamnosus. The preparation method comprises the following steps of respectively inoculating each strain into a corresponding sterilization culture medium, activating, and preparing a first-level seed liquid; according to the neighboring and mutualism principle, during second-level and third-level fermenting, mixing and fermenting the saccharomyces cerevisiae and candida utilis, mixing and fermenting the bacillus subtilis and bacillus licheniformis, and mixing and fermenting the rhodopseudomonas palustris, lactobacillus plantarum and lactobacillus rhamnosus; mixing the three mixed and enlarged culture bacteria liquids according to the equal volume of 1:1:1, absorbing onto sterilizing wheat bran-rice bran, and performing solid fermenting and low-temperature drying, so as to obtain the solid microbial agent. The poultry and livestock intestinal ecological restoration microbial agent has the characteristics that the good properties of high density and high activity are realized; the probiotics microbial agent and the lemon and radix astragali seu hedysari water extracting liquid are compounded for first time; the usage amount is less, and the use method is simple and convenient.

Description

Technical field [0001] The invention belongs to microbial fermentation technology, in particular to an antiviral and antibacterial antibacterial agent for ecological restoration of poultry intestinal tract instead of antibiotics and a preparation method thereof. Background technique [0002] For a long time, a large number of or even abused antibiotics in the poultry breeding industry not only made pathogenic microorganisms resistant, but also seriously damaged the ecological balance of poultry intestinal flora, resulting in immunosuppression, low immunity, and disease resistance in poultry and livestock. The capacity is weakened, so viral and bacterial infections increase. The multiple outbreaks of avian influenza in spring and autumn each year are proof. Moreover, in the face of viral colds and viral intestinal diseases, except for individual cases that can be prevented by vaccination, they are almost helpless in the face of constantly mutating viral infections. They can ...
