Abstract

The present invention relates to a method for preparing fodder from crops stalks, specially for preparing the fodder for non-ruminant by using rice straw. The method consists of crushing the rice straw, ammoniation,d rying and deammoniation, adding adjuncts and additive, inoculating the mixed saccharomyces and undergoing the solid fermentation, and the non-ruminant fodder is prepared up after drying.

Description

Stalk fermentation prepares the method for monogastric animal feed

The invention belongs to the feed processing technology field, relate to the method for preparing feed with agricultural crop straw, more particularly the present invention relates to produce the method for monogastric animal feed with straw.

Agricultural crop straw is the byproduct of a kind of agricultural production of quantity maximum, and wherein straw is often used as fuel or neg material.From the purpose of food production, the contained nutriment of agricultural crop straw is converted into products such as meat, egg, milk effectively has very big attraction undoubtedly by animal.Address this problem the food production amount that can improve the soil, remedy the deficiency of feed-use grain, alleviate the contradiction that people and animals strive grain.

Straw should not be its content of lignin height as the main cause of monogastric animal feed, the crude fiber content height, and protein content is low, so digestibility and palatability are all very poor.The method of currently used physics and chemical treatment stalk, just for strengthening contacting of stalk and rumen microorganism, or dissolving part lignin, make rumen fluid be easy to infiltration, but all fundamentally do not change the character of stalk and only can be used as ruminant feed.CN1037070 discloses and a kind of straw and other crop material has been pulverized the high-pressure bottle of packing into, impels crude fibre and lignin in the material that the method for making feed takes place to transform under the effect of high temperature, high pressure.Though this method is simple, part hemicellulose and cellulose are softened, can not significantly reduce its crude fiber content, improve the content of crude protein, also should not be as the feed of nonruminant.

The purpose of this invention is to provide a kind of agricultural crop straw of using, particularly select the method that is difficult to prepare the monogastric animal feed that crude fiber content is low, crude protein content is high for use as the straw fermentation method of feedstuff.

Purpose of the present invention can be achieved through the following technical solutions:

A kind ofly be equipped with the method for monogastric animal feed with the fermenting crops straws legal system, its key problem in technology is:

1, stalk is through pulverizing, add NH ₄The airtight ammonification of OH aqueous fusion liquid, adds an amount of auxiliary material, additive and water at dry deamination, mixes, and inserts the mixed bacteria solid fermentation through spreading cultivation, and feed product is made in last drying and pulverizing.

2, in the ratio of stalk with the ratio 1: 0.2～1 of ammoniacal liquor, adding concentration is 3～10% NH in the stalk of pulverizing ₄The OH aqueous solution, ammonification is 100～220 hours under air-tight state.

3, ammonification finishes back drying deamination.

4, in the stalk of deamination, add the wheat bran that accounts for stalk weight 10～20% (W/W), the terramycin of the calcium dihydrogen phosphate of 1～5% (W/W), 0.3～2% (W/W) ammonium sulfate and 5～200,000 units/kilogram stalk.

5, insert the mixed bacteria that, aspergillus mould by wood through spreading cultivation and yeast are formed, mix, ferment, wooden mould content is more than 60% in the mixed bacteria.

6, fermentation temperature is controlled at 15～40 ℃, fermentation time 100～150 hours.

7, the material drying after the fermentation is made feed product through pulverizing again to below moisture 11% (W/W).

Feature with the feed product of this method preparation is that crude fiber content is low, the crude protein content height.

The advantage that the present invention had is:

1, can effectively utilize agricultural crop straw such as straw, the exploitation feed resource;

2, the feed product of making can be for feeding nonruminant as the substitute of feedstuffs such as rice bran, wheat bran;

3, full fiber percent hydrolysis height, the manufactured goods crude fiber content is low, the crude protein content height;

4, production technology advantages of simple, required small investment, production cost is low;

5, non-environmental-pollution suits to apply in vast rural area.

Be described in further detail the utility model below in conjunction with embodiment.

Accompanying drawing is a process chart of the present invention.

Below be embodiments of the invention.

With reference to accompanying drawing, the straw of some is pulverized earlier, press straw and NH ₄1: 0.5 ratio of OH aqueous solution adding concentration is 3% NH ₄The OH aqueous solution, airtight ammonification 150 hours, the natural air drying deamination is to non-stimulated flavor then; Add 10% wheat bran (W/W) again, 3% calcium dihydrogen phosphate (W/W), the terramycin of 1.0% ammonium sulfate (W/W) and 50,000 units/kilogram straw mixes; Access is mould by 60% wood through what spread cultivation, and all the other are the mixed bacteria that aspergillus and yeast are formed; Under 20～25 ℃ temperature, fermented 150 hours, the drying machine is dried to below moisture 11% (W/W); Pulverize with pulverizer at last and make the monogastric animal feed product.Wherein the product crude fiber content can reduce to 15～18%.
