Abstract

The invention provides straw feed prepared by an anaerobic fermentation method. The method comprises the following concrete steps that (1) concentrated collection is performed on harvested straws, and then, the harvested straws are crushed to obtain straw coarse powder; (2) raw materials uniformly stirred in the step (1) are fed into a steamer; the materials are pre-steamed for 30 to 40 minutes at the temperature being 90 to 110 DEG C; the materials are taken out, and are cooled; the sterilization and curing effects can be achieved through pre-steaming, and the subsequent fermentation is easy; (3) the cooled raw materials in the step (2) are fed into a fermentation pool; anaerobic fermentation is performed for 4 to 7 days in a way of adopting water sealing; (4) raw materials subjected to anaerobic fermentation in the step (3) are taken out, and are naturally put for 2 to 3 days in environment with the temperature being 18 to 28 DEG C and the humidity being 45 to 65 percent; the piling thickness of the raw materials cannot exceed 0.3m; the raw materials can be turned once in the piling process, so that harmful gas in the raw materials can be properly volatilized; (5) the raw materials put in the step (4) are dried and palletized to obtain the straw feed.

Description

A kind of straw feed adopting anaerobic fermentation method to prepare

Technical field:

The present invention relates to field of feed, specifically a kind of straw feed adopting anaerobic fermentation method to prepare.

Background technology:

China is large agricultural country, and stalk resource enriches, and agricultural crop straw is a kind of important living resources, can pass through various ways trans-utilization.But in recent years, along with the transformation of tillage method, life style, crops straw returning field effect is undesirable, peasant's crop straw burning phenomenon is caused to remain incessant after repeated prohibition.Crop straw burning phenomenon is very serious, and severe contamination environment, directly affect traffic safety and resident living, stalk taboo burning is imperative.

Crops Straw Silage has a lot of benefit: nutritive loss is few, is generally no more than 10%, the rich in nutrition content such as digestible vitamin, protein, fat, the sour-sweet fragrance of smell, digestibility is high, good palatability, can appetite be increased, promote digestion, can feed for the four seasons.But traditional storing technology also exists many deficiencies.Due to can not compacting, in stalk, the air of surplus be too much, causes aerobic bacteria amount reproduction, makes that feed is mouldy to rot; Getting in the process of raising, air invades in cellar for storing things, causes going mouldy of a new round.Tradition ensilage total losses amount up to 30%, and owing to having musty in feed, can have a strong impact on searching for food of milk cow.

Summary of the invention:

Technical problem to be solved by this invention is to provide a kind of straw feed adopting anaerobic fermentation method to prepare, and can improve the utilization rate of stalk, reduces Feed Manufacturing cost.

In order to realize the technical solution adopted in the present invention

Adopt a straw feed prepared by anaerobic fermentation method, concrete grammar step is as follows:

(1) centralized collection is carried out to harvested stalk, then pulverize, obtain stalk meal, red yeast rice 500 grams is admixed in every 1 ton of stalk meal, 400 grams, garlic leaf, folium sennae 500 grams, balsam pear slice 500 grams, purple potato fourth 500 grams, grape wine 300 grams, beer 2000 grams, luffa vine 250 grams, salt 250 grams, sweet taste peptide 80 grams, smear tea 200 grams, 500 grams, grape pip powder, 500 grams, purple perilla seed powder, 500 grams, Radix Sorghum vulgare Pers powder, wheat oligopeptide 300 grams, lutein ester 200 grams, Honegsukle flower P.E 200 grams, Caulis et Folium Brassicae capitatae 200 grams, zytase 200 grams, the sophora bud 250 grams, sweet osmanthus 250 grams, lemon grass (Cymbopogon citratus) 250 grams and gingili leaf 250 grams, mix thoroughly,

(2) raw material after mixing thoroughly in step (1) is sent into food steamer, steam 30-40 minute in advance at the temperature of 90-110 DEG C, cool after taking-up; Sterilization and maturation can be played by steaming in advance, being easy to follow-up fermentation;

(3) raw material after cooling in step (2) is sent into fermentation vat, adopt water-stop, carry out anaerobic fermentation 4-7 days;

(4) being taken out by raw material good for anaerobic fermentation in step (3), is 18-28 DEG C in temperature, and humidity is naturally place 2-3 days under the environment of 45-65%; Notice that the stacking thickness of raw material is not easily more than 0.3 meter, centre can be stirred once, and the middle pernicious gas of raw material is volatilized in right amount;

(5) raw material after placing in step (4) is carried out drying, namely granulation obtain straw feed.

The present invention is under the effect of the high-performance bio factor (various catabolic enzyme, multiple-microorganism viable bacteria), by the ester bond generation enzymolysis of the crude fibre (cellulose, hemicellulose) in stalk, the long strand of lignin, xylan, lignifying compound, nonabsorbable for animal polymeric carbohydrate is changed into the low molecular weight carbohydrate of Absorbable rod utilization, i.e. energy feed; Multiple-microorganism viable bacteria can draw organic nitrogen, the inorganic nitrogen that animal is difficult to utilize in a large number, makes it to change into nutrition more much higher kind of bacterium protein, i.e. protein feed; Multiple-microorganism viable bacteria can produce a large amount of protease, lipase, amylase, cellulolytic enzyme in fermentation, B family vitamin and A, D vitamin; Multiple-microorganism viable bacteria sets up microecological balance in animal body, enhances immunity.Feed of the present invention may be used for poultry, as pig, sheep, ox etc.

The invention has the beneficial effects as follows: straw feed fragrance prepared by the present invention assails the nostrils, bent thick flavor, livestock and poultry are liked to eat, and just sleep after eating, and growth is express, crude fibre declines about 45%, containing abundant bacterium protein (10.2%-15%), improve livestock speed of weight increment 4%-10%, substitute 30%-50% concentrated feed, effective, cost is low.Feed growing and fattening pigs, every day can long 1.3-1.8 jin.Make ox, sheep, rabbit feed, every 100 kilograms of grass meals, increase protein 3-5 kilogram.

Detailed description of the invention:

The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with instantiation, setting forth the present invention further.
