Microorganism group feed additive with plurality of beneficial functions, and manufacturing method thereof

Abstract

The invention discloses a microorganism group feed additive with a plurality of beneficial functions. The microorganism group feed additive is composed of a plurality of beneficial microorganisms, metabolic products thereof, and viable bacteria of saccharomycetes, lactic acid bacteria, and acetic acid bacteria. A manufacturing method comprises following steps: beneficial microorganisms are selected; nutritional elements needed by the microorganisms are used for preparing a culture medium stock solution, wherein the content of sulphur element accounts for 2.1 to 5.8% of the total amount of the nutritional elements; the culture medium stock solution is subjected to beneficial microorganism inoculation; after culturing, a new culture medium solution containing the beneficial microorganisms and the metabolic products thereof is obtained, and is subjected to sterilization so as to kill viable bacteria in the new culture medium solution; and then the new culture medium solution is inoculated with lactic acid bacteria, acetic acid bacteria, and saccharomycetes for culturing. The manufacturing method is simple; effects of the plurality of the microorganisms are achieved; disease fatality rate is reduced; weight is increased; manure offensive odor is reduced; livestock and poultry growing environment is improved; livestock and poultry meat quality is improved substantially; and the microorganism group feed additive is mainly used as a feed additive of feeds of livestock, poultry, and aquatic organisms.

Description

Technical field: [0001] The invention relates to a group microbial feed additive with multiple beneficial functions and a preparation method thereof, which is suitable for raising any poultry, livestock and aquatic products. Background technique: [0002] Existing microbial feed and microbial feed additives are reported in literature both at home and abroad. However, because there is no way to overcome the mutual inhibition of different microorganisms, existing microbial feed and microbial feed additives can only use a single microbial strain or mix multiple microorganisms into powder, and the microorganisms therein are either inactivated or In the dormant state, because of the death of bacteria during the production process, as a feed additive, it has poor effects in promoting the growth of poultry, livestock, and aquatic products, disease resistance, and deodorization of feces. The existing method of making microbes into dry powder and then mixing them not only causes the...

Problems solved by technology

However, its technology is in a state of complete secrecy, and there is no way to check the bacteria species, the number of strains, the culture method and whether it contains harmful microorganisms in its products.

In practical application, although it has a certain effect on promoting growth, disease resistance, and feces deodorization, it is not obvious, and basically has no effect on improving meat quality
