Method for producing complex micro-ecological preparation with microbial agents and enzyme

Abstract

The invention discloses a method for producing a complex micro-ecological preparation with microbial agents and enzyme. According to the action principles and characteristics of every microbial strain, the method adopts scientific combination and adds enzyme preparations and acidifier to enable microorganisms in the product to grow rapidly and take dominance in fermented feed and animal bodies so as to reduce the growth opportunity of miscellaneous bacteria. The preparation comprises the following components: bacillus subtilis, lactobacillus plantarum, candida utilis yeast, lactobacillus acidophilus, protease, amylase, cellulase, xylanase, mannanase, galactosidase, pectinase and citric acid. As all strains of the product adopt liquid deep fermentation culture, the non-polluting property of the product is guaranteed. Liquid microbial agents ensure that the number of bacterial colonies of the product is more than 100 million and the product is free from the pollution of other miscellaneous bacteria, while solid microbial agents ensure that the number of bacterial colonies of the product is more than 1 billion and the proportion of miscellaneous bacteria to effective bacteria is not more than 0.0001. The preparation contains bacillus, lactic acid bacteria and yeast, can apply to the processes of making green-yellow storage feed, fermenting feed, soaking feed, and the like, can be directly added to feed for feeding, and can improve the growth performance of ruminant animals, poultry, pigs, aquatic products and special animals.

Description

technical field [0001] The invention relates to a compound microbial preparation of bacteria and enzymes. technical background [0002] As feed additives for livestock and poultry, antibiotics have been strictly restricted or even banned in many countries due to problems such as residues and drug resistance in livestock and poultry products. In order to seek alternatives, the World Health Organization (WHO), the Food and Agriculture Organization of the United Nations (FAO), the United States, Japan and other countries attach great importance to the development of alternatives to antibiotics. my country also attaches great importance to research in this area, and has formulated normative documents such as the "Selection Catalog of Feed Additives". At present, the United States, Japan, Europe, Central and South America, Southeast Asia and other places are using feed live bacteria agents, and it has been proved that it is harmless to livestock and poultry and their products, h...

Problems solved by technology

However, most domestic strains have not been selected according to the scope of strains specified in this requirement, so there is a potential risk of disease

[0009] 2. The selection of bacterial strains in most microecological preparations does not follow the principle of complementarity. Among the major functions of the above-mentioned microecological preparations, not a single strain or a group of bacteria of the same kind can be effective, and several different types of microorganisms are required. The synergistic effect of bacteria can achieve the above effect

[0010] 3. Most domestic microecological preparations are produced using extensive processes such as solid fermentation. The products produced often coexist with target bacteria and polluted bacteria, which seriously affects the use effect of the products.
