Problems solved by technology

The microbial feed additives currently produced in China still have a large gap with foreign products in many aspects. The main manifestations are: domestic microbial feed additives mostly use solid fermentation, which makes the quality of many products unstable, the number of effective viable bacteria is insufficient, and product pollution (Sometimes even a large amount of mold is detected in the product); the domestic direct drying method makes the appearance of the product rough and the shelf life is short; domestic products are mixed, the product description exaggerates its efficacy, and the actual effect is not obvious; Addition of domestic products is high

example 1

[0017] Example 1: Production of compound microecological feed additive-synbiotic preparation

[0018] (1) Take xylo-oligosaccharides and chitosan-oligosaccharides produced by enzymatic hydrolysis respectively, at freezing temperature -20~65°C, lactic acid bacteria powder made under vacuum 15~45Pa, after liquid culture and separation, in 35 Yeast culture dried at ~55°C, Bacillus subtilis powder dried at 40~60°C.

[0019] (2) Calculated by weight ratio, take 0.15Kg of xylooligosaccharide, 0.58Kg of chitosan oligosaccharide, 0.02Kg of freeze-dried lactic acid bacteria powder, 0.08Kg of yeast culture, and 0.45Kg of Bacillus subtilis, and use the coefficient of variation of mixing uniformity The double-shaft paddle-type high-efficiency mixer with less than 5% mixes evenly, and the packaging is made of paper plastic and composite aluminum foil bags. The storage temperature is less than 35°C, and the storage environment humidity is less than 60%.

example 2

[0020] Example 2: Production of compound microecological feed additive-synbiotic preparation

[0021] Raw material is with example 1. The ratio of raw materials is as follows: 0.35Kg of xylooligosaccharide, 0.15Kg of chitosan oligosaccharide, 0.15Kg of freeze-dried lactic acid bacteria powder, 0.45Kg of yeast culture, and 0.03Kg of Bacillus subtilis. Method of making is made product with example 1.

example 3

[0022] Example 3: Production of compound microecological feed additive-synbiotic preparation

Abstract

A composite microbial additive of forage for preventing and treating diarrhea, promoting growth, suppressing and decreasing the putrefactive bacteria and pathogenic bacteria, and decreasing the exhaust of harmful gas in dung is proportionally prepared from oligoxylose, oligochitosan, freeze-dried lactobacillus powder, the yeast culture and Bcillus subtitis through mixing.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to the technology of microbial preparation as a feed additive and its preparation method. Background technique [0002] Internationally, since the discovery of various disadvantages of antibiotics in the animal breeding industry in the 1960s, attention has been paid to the research, development and use of microbial feed additives. The United States began to use feed microorganisms in the 1970s. Currently, there are more than 40 kinds of microorganisms that are allowed to be fed directly, with an annual usage of more than 8,000 tons. In Europe alone, there were no less than 50 probiotic varieties sold on the market in France in 1991. Japan, Germany, Britain and other countries have successively developed new antibiotic substitute products and put them into mass production more than 10 years ago, which has enabled the rapid development of microbial preparations. The United State...
