Micro-ecological preparation for feed and preparation method thereof

Abstract

The invention provides a micro-ecological preparation for a feed and a preparation method thereof. The method comprises the following steps of: firstly, performing liquid state fermentation on primary and secondary seeds by using 5 strains, namely lactobacillus plantarum, lactococcus lactis, lactobacillus rhamnosus, aspergillus niger and saccharomycopsis fibuligera; secondly, uniformly mixing high temperature soybean meal, wheat bran, corn meal and rice hulls in a weight ratio of (20-25):(50-60):(18-20):(3-5); adding 18 percent solution of urea in an amount which is 15 to 20 weight percent of the mixture into the mixture; inoculating liquid secondary seeds in an amount which is 5 percent of a humid weight of the solid mixture; uniformly mixing the mixture; flattening the solid mixture to a thickness of 12 to 20cm; culturing the solid mixture at the temperature of 30 DEG C for 48 hours; performing ventilation drying on the cultured solid mixture at the temperature of between 40 and 45 DEG C and stopping drying till the moisture content of the solid mixture is less than 5 percent; and crushing and packaging the solid mixture to obtain the finished products.

Description

(1) Technical field [0001] The invention relates to a biological preparation for feed, and also relates to a preparation method of the biological preparation. (2) Background technology [0002] The so-called feed microecological preparation is a safe, pollution-free and residue-free feed microbial preparation containing active probiotics, which is made by mixing known beneficial microorganisms and nutrient carriers through special processes such as fermentation and drying under the guidance of microecological theory. In 2000, the British "mad cow disease" incident and the Belgian "dioxin" incident occurred successively in the world, which caused panic among people all over the world and caused strong shocks in the European continent. Consumers' confidence in animal products was in a serious crisis. People began to strongly call for green feed, and put forward slogans such as "creating healthy food with healthy feed" and "feed is direct food for human beings". The safety of f...

Problems solved by technology

According to statistics, the country produces 2 million tons of various biological feeds annually. Compared with foreign countries, my country's biological feeds have fewer varieties, lower output, and higher prices, and many products have not yet formed large-scale production, which cannot meet the needs of the development of aquaculture production for the time being. need
