Microbial fodder additive and its preparing method and use

Abstract

The present invention relates to microbial fodder additive, and a kind of microbial fodder additive comprising beneficial microbes and their metabolites and its preparation process and use. The microbial fodder additive is the mixture of fermented liquid or dry powder obtained with Bacillus subtilis, Bacillus cereus, lactobacillus and Saccharomyices cerevisiae and through high density deep layer liquid fermentation. It may be prepared into different specific liquid or powder preparations. The microbial fodder additive has high live bacillus content, long product preserving period and less foreign bacteria contamination, and has the functions of raise fodder utilization, promote animal's growth, increase animal product yield and quality, etc.

Description

technical field

[0001] The invention relates to a microbial feed additive, in particular to a microbial feed additive composed of various beneficial microorganisms and their metabolites (such as protease, lipase, amylase, cellulase, etc.) and its preparation method and use. Background technique

[0002] The use of some growth-promoting health care agents in feed industry and breeding industry has promoted the rapid development of animal husbandry, but at the same time it has brought many potential threats to human health and the development of feed industry. At present, the abuse of antibiotics, chemical synthetic drugs, hormones, β-stimulants, heavy metals, sedatives and other growth-promoting health care agents in feed and livestock breeding has led to a series of problems and consequences: (1) leading to serious drug residues in livestock and poultry products, directly It is harmful to human health, and even produces "three diseases", and makes my country's livestock and ...
