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 the xylo-oligosaccharides and oligo-chitosan produced by the enzymatic hydrolysis method, respectively, and prepare the lactic acid bacteria powder at a freezing temperature of -20~65℃ and a vacuum degree of 15~45Pa. Yeast culture dried at a temperature of ~55℃, and Bacillus subtilis powder dried at a temperature of 40-60℃.

[0019] (2) Calculate according to the weight ratio, take 0.15Kg of xylo-oligosaccharide, 0.58Kg of oligochitosan, 0.02Kg of freeze-dried lactic acid bacteria powder, 0.08Kg of yeast culture, 0.45Kg of Bacillus subtilis, and use the coefficient of variation of mixing uniformity The biaxial paddle type high-efficiency mixer with less than 5% mixes evenly, and the packaging uses 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] The raw materials are the same as in Example 1. The raw material ratio is: 0.35Kg of xylo-oligosaccharide, 0.15Kg of oligochitosan, 0.15Kg of freeze-dried lactic acid bacteria powder, 0.45Kg of yeast culture, and 0.03Kg of Bacillus subtilis. The manufacturing method is the same as that of Example 1 to make the product.

example 3

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

[0023] The raw materials are the same as in Example 1. The raw material ratio is: 0.21Kg of xylo-oligosaccharide, 0.30Kg of oligochitosan, 0.18Kg of freeze-dried lactic acid bacteria powder, 0.15Kg of yeast culture, and 0.18Kg of Bacillus subtilis. The manufacturing method is the same as that of Example 1 to make the product.

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 present invention belongs to the technical field of animal feed, in particular to the technology of using microbial preparation as feed additive and its preparation method. Background technique [0002] The international community began to pay attention to the research, development and use of microbial feed additives after discovering the various drawbacks of antibiotics in the animal feeding industry in the 1960s. The United States began to use feed microorganisms in the 1970s. At present, there are more than 40 kinds of microorganisms that are allowed to be directly fed, and the annual consumption is about 8,000 tons. There were no less than 50 probiotics on the market in France in 1991 in Europe. Japan, Germany, Britain and other countries have successively developed new types of antibiotic substitute products and put them into mass production more than 10 years ago, enabling the rapid development of microbial preparations. The United States and some...
