Preparation method of Chinese herbal component-containing poultry yeast fermentation culture

Abstract

The invention discloses a preparation method of a Chinese herbal component-containing poultry yeast fermentation culture. A yeast strain is subjected to aerobic breeding and enlarged culture, is thensubjected to liquid anaerobic fermentation, and is then mixed with a solid fermentation substrate. Through aerobic-anaerobic fermentation treatment, astragalus membranaceus, wild chrysanthemum flowersand radix sophorae flavescentis are added into a conventional yeast culture medium, so that the metaboilic level of organ substances can be adjusted and controlled; the Chinese herbal component-containing poultry yeast fermentation culture contributes to maintaining and increasing the antibody level, and the pharmacodynamic action of Chinese herb extracts is fully exerted; when used for poultry,the prevention and treatment effects on animal diseases can be enhanced; meanwhile, the fermentation production period can be effectively shortened, and the feed palatability can be improved. The fermentation culture disclosed by the invention can supplement and improve daily feed nutrition, adjust microfloras of organ intestinal tracts, relieve stress reactions of animals to the environment, enhance the immunity of the animals, and increase the economical benefit.

Description

Technical field [0001] The invention relates to the technical field of fermented feeds, in particular to a method for preparing a fermented poultry yeast culture containing Chinese medicine components. Background technique [0002] Yeast Culture, as a kind of microecological preparation, also known as synbiotics, is composed of live yeast cells, yeast metabolites and its culture medium. It is formed by anaerobic fermentation of specific fermentation process and can provide abundant Nutrients, such as B vitamins, amino acids, digestion promoting factors~enzymes, organic acids (lactic acid, malic acid, formic acid, succinic acid), minerals, some esters, alcohols and unknown growth factors, etc. Because β-glucan, mannan and other substances have a certain degree of immunogenicity, and also have health care effects, such as balancing the intestinal microflora, inhibiting the reproduction of pathogenic microorganisms and improving animal immunity, domestic and foreign scholars have p...

Problems solved by technology

[0002] Yeast Culture (Yeast Culture), as a kind of probiotics, or called synbiotics, is composed of yeast living cells, yeast metabolites and their culture medium. It is anaerobically fermented through a specific fermentation process and can provide rich Nutrients, such as B vitamins, amino acids, digestive factors~enzymes, organic acids (lactic acid, malic acid, formic acid, succinic acid), minerals, some esters, alcohols and unknown growth factors, etc. At the same time, Because β-glucan, mannan and other substances have certain immunogenicity and health care effects, such as balancing the intestinal microflora, inhibiting the reproduction of pathogenic microorganisms and improving animal immunity, domestic and foreign scholars have proved through a large number of studies , Yeast culture has a great effect on animal production performance and intestinal function regulation. For example, adding YC to the diet can increase the body weight and feed efficiency of beef cattle, and can also change rumen fermentation, increase rumen lactic acid utilization bacteria and fiber Decompose bacteria, increase digestibility, increase the concentration of rumen bacteria, etc. However, the effect of probiotics on the prevention and treatment of animal diseases is limited, and the use effect cannot be reflected in a short period of time is one of the major drawbacks
