Technical Field
The invention belongs to the technical field of biological feed, and particularly relates to a fermented feed for ruminants and a preparation method thereof.
Background
The corn is one of three main grain crops in the world and is also one of three main grain varieties in China, and the corn serving as the second grain crop in China has the yield accounting for about 35 percent of the total yield of grains in China. Corn in China is mainly used for producing feed for a long time, but with the change of social requirements and the continuous development and progress of corn deep processing industry, the consumption structure of corn gradually changes.
Although the corn deep processing industry can create economic growth, the corn deep processing industry in China has many insufficient places. The main problems are that the industrial chain is not long enough, the added value is not enough, the production efficiency is low and the like in the deep processing production process of the corn. In particular, the corn deep processing byproducts are high in yield, but the economic value of the corn deep processing byproducts is low, wherein byproducts generated in the corn starch production process are a prominent problem. The production of starch by corn is the major mode of the corn processing industry, since the production of starch is around 2000 million tons per year, and the corn starch accounts for about 80-85%. Wherein the byproducts of the wet-process production of the corn starch mainly comprise corn oil, corn germ meal, corn steep liquor, corn husks, corn starch residues, corn DDGS and the like. The produced byproducts can be applied to production and life, and meanwhile, some byproducts which are difficult to directly utilize are also produced: corn bran, corn steep liquor, corn germ meal, corn starch residue and the like, wherein the byproducts are not subjected to deep processing and are generally sold separately and are low in price.
The glutamic acid fermentation wastewater is obtained by extracting glutamic acid and mycoprotein and then evaporating and concentrating in the glutamic acid fermentation production process, and has high COD and NH3The characteristics of N, high salt and low pH, namely three highs and one lowness, are once the symbols of the high and heavy pollution industry in China, the waste water is usually used for preparing nitrogen fertilizer after being developed, the additional value generated by the utilization mode is low, a utilization mode with higher economic benefit needs to be searched, and the biological feed technology is an effective way.
The biological feed is a general name of a novel feed resource and a feed additive which are safe, efficient, environment-friendly and free of residue and are developed by using microbial engineering fermentation by taking feed and a feed additive as objects and taking modern biotechnology such as genetic engineering, protein engineering, fermentation engineering and the like as means. The categories mainly include: feed enzyme preparations, microbial feed additives, functional protein peptides, functional amino acids, organic trace elements, plant and microbial extracts, prebiotics, fermented and enzymolyzed feeds and other biotechnology related products can be classified as biological feed additives and biological fermented feeds. Part of the corn by-products, the miscellaneous meal and the glutamic acid fermentation wastewater are subjected to bacterium-enzyme synergistic fermentation treatment to prepare fermented feed for ruminants, so that the additional value of the raw materials can be effectively increased, the problem of environmental pollution caused by the glutamic acid fermentation wastewater is relieved, and certain economic benefit is brought to enterprises.

The preparation method comprises the following steps of preparing a ruminant fermented feed by adopting a two-step fermentation method, wherein in the first step, liquid fermentation is carried out, rumen coccus, eubacteria and rumen coccus amylovorus are prepared into seed liquid, and inorganic nitrogen in a nitrogen source is converted into microbial mycoprotein by microorganisms in the microbial proliferation process; and secondly, performing bacterium-enzyme synergistic fermentation, namely adding the bacterium-enzyme into the seed liquid, adding the bacterium-enzyme into the solid raw material, fermenting for a certain time at a certain temperature, and obtaining the fermented feed for the ruminants after the fermentation is finished.
Bacillus licheniformis can produce alpha-amylase, alkaline protease for hydrolyzing starch and protein in feed, and enzyme for hydrolyzing cellulose. The bacillus subtilis itself synthesizes enzymes such as alpha-amylase, protease, lipase, cellulase, etc., and can decompose and utilize residual starch, protein, fat and cellulose in the first mixture. The proliferation of yeast can metabolize to produce acetic acid and ethanol, improve the smell of materials and prevent the growth and reproduction of mold. The proliferation of lactic acid bacteria can be metabolized to produce lactic acid, and the growth and reproduction of mixed bacteria can be inhibited. Monosaccharides generated by enzymolysis of xylan and cellulose by xylanase and acidic cellulase can be used as a carbon source by microorganisms, and the effect of promoting proliferation of the microorganisms is achieved.
The xylanase is a complex enzyme system for degrading xylan molecules, has complex composition and comprises beta-xylanase, beta-D-xylosidase, alpha-L-furan type arabinosidase, acetyl xylan esterase, phenolic acid esterase and the like, wherein the beta-xylanase is a main enzyme for degrading hemicellulose, and the enzyme acts on beta-1, 4-xyloside bonds inside a xylan main chain in an internal mode to degrade xylan into short-chain xylo-oligosaccharides, and a small amount of xylose is generated; and the beta-D-xylosidase acts on short-chain xylooligosaccharide and catalyzes the tail end of the xylooligosaccharide to release xylose residues. Cellulases belong to glycoside hydrolases and are traditionally divided into three groups of components: 1. endoglucanases, commonly known as CX enzymes, and EG enzymes from fungi; 2. exoglucanases, i.e., cellobiohydrolases, commonly known as the C1 enzyme, known as CBH from fungi; 3. beta-glucosidase, abbreviated as BG. Cellulases degrade cellulose as a result of a synergistic interaction between the components of the enzyme.
The acidic protease is widely present in mould, yeast and basidiomycetes, and is rarely found in bacteria, mainly carboxyl protease, the active center of which contains two aspartic acid residues, the content of the acidic amino acid is high, the content of the basic amino acid is low, the optimum pH value is 2.0-4.0, and the optimum temperature is about 40 ℃.
