Abstract

The invention relates to a feed additive, in particular to a compound microbial agent and a production method thereof. Candida utilis, enterococcus faecalis, lactobacillus acidophilus and bacillus subtilis are compounded to be cultured in a culture medium until the pH value is 2.5-3.5 to obtain the compound microbial agent in parts by weight: 1-3 parts of Candida utilis, 1-3 parts of enterococcus faecalis, 1-3 parts of lactobacillus acidophilus and 1-3 parts of bacillus subtilis. The compound microbial agent can serve as the feed additive of animals. The invention adopts the mode that various strains are combined to obtain strong acid state flora with different acidity degrees according to culture medium components, culture temperature and different ratios of various strains; according to animal types and different adopted feeds, and the advantages of the strong acid state flora can be performed to improve animal disease resistance, improve economic benefit and optimize environment.

Description

technical field [0001] The invention relates to a feed additive, in particular to a compound microbial agent and its production method and application. Background technique [0002] At present, most of the existing microbial additive products are mainly cultivated by a single strain. The compound microbial flora mostly uses bacteria of the same species and genus with similar or similar characteristics to form compound probiotics. This compound bacteria has a single component of bacterial metabolites; the effect is not ideal; the product effect is unstable; control issues. The microbial feed additives produced by such single flora and compound flora have the disadvantages of single efficacy, roughness, lack of systematicness, and poor acidification of feed, which brings a lot of inconvenience to the development of microbial feed additives. Contents of the invention [0003] One of the objectives of the present invention is to provide an aerobic, anaerobic and facultative ...
