Abstract
The present invention belongs to animal feed extracted from vegetable materials, particularly to feedstuff extracted from straws and an extraction method thereof. Sacchariferous feedstuff with high protein is biochemical feedstuff which is prepared by crushing vegetable straws, carrying out hydrolytic treatment and saccharification, fermenting by microorganisms, and dehydrating and drying. Other raw materials can be added to the sacchariferous feedstuff with high protein to be prepared into the feedstuff which is suitable for various kinds of livestock according to the variety and the growth phase of the livestock, and the sacchariferous feedstuff with high protein can be directly used for feeding various kinds of livestock. The sacchariferous feedstuff with high protein can save lots of grains for livestock breeding, and has the advantages of overall nutrient components, low cost and obvious economic benefit.
Description
The invention belongs to the animal feed that extracts from vegetable material, feed that particularly from stalk, extracts and extracting method thereof.
Present existing feed is that the primary raw material cooperation forms with corn, wheat bran, sweet potato, soya-bean cake, the dregs of fat, fishbone dust class and traditional grain crop still.These feeds not only cost an arm and a leg, and consume a large amount of grains.Especially these feeds are many is primary raw material with stiff five cereals, needs by the digestive system in the body it to be transformed and can absorb after the domestic animal feed, thereby causes very big waste.China is a populous nation, have a large population and a few land, in recent years along with the continuous development of building of the four modernizations, though grain is self-supporting substantially, but taking out greatly, grain is used for aquaculture production, still some deficiency is also at present striven ground in order to solve people and animals, people and animals strive this contradiction of grain, and the feed of seeking to develop novel and economically valuable has become the important topic that current aquaculture whether can high speed development.
The purpose of this invention is to provide a kind of high-protein sacchariferous feed and manufacture method thereof, utilize the stalk of crops to form through microbial fermentation, this feed cost is low, raw material sources are wide, nutritious, be suitable for the nursing of various domestic animals, the development aquaculture is had very big practical value, can alleviate people and animals again simultaneously and strive this contradiction of grain.
The present invention is achieved in that the discarded stalk (as cornstalk, corncob, straw, straw, cotton seed hulls etc.) that utilizes crops is through pulverizing, sieve and utilize behind the hydrolysis and saccharification in addition again the fermentating breeding of microorganism, after making the rich nutrient substances such as carbohydrate, protein and amino acid that wherein obtain capacity, a kind of feed that dehydration, drying are made.This high-protein sacchariferous feed, be to utilize cellulose, hemicellulose in the plant refuse behind hydrolysis and saccharification, its whole hydrolysate to be passed through the fermentating breeding of microorganism, dehydrate then and form, both kept the nutrient composition in original plant, again by biochemical process, cellulose etc. is converted into the nutriment of sugar, protein, amino acids.The shape of this feed can be a flour, also can be coarse particulate material at random, also can make effigurate particulate material by mechanical pelleting.This feed can also add other an amount of nutriment as the masterbatch in the feed, forms the mixed fodder that is fit to various domestic animals.
The manufacture method of high-protein sacchariferous feed of the present invention comprises the steps:
A. with the straw drying, after pulverizing, sieving the powder of moisture content≤15%, impure amount≤15%;
B. be 0.2～6% dilute sulfuric acid with gained powder and mass percent concentration in the steps A, with mass ratio be 1: 2.5～5 solid-to-liquid ratio puddle the back under 100～180 ℃ of temperature hydrolysis 4～180 minutes hydrolysate;
C. with step B gained hydrolysate through centrifugal action, the solid, liquid attitude is separated, the liquid after separating is filtered then with milk of lime or lime neutralization, with the gained clarified solution with centrifugal after the solid matter that separates puddle, regulate pH value again, must hydrolysis puddle thing;
D. puddle in the hydrolysis of step C gained that to puddle into mass percent in the thing again be 1% calcium superphosphate leachate, 2% urea, 5% corn flour, inserting the active dry yeasr bacterial classification then ferments, fermentation time is 24～48 hours, gets moisture high-protein sacchariferous feed;
E. the moisture high-protein sacchariferous feed of step D gained is promptly got high-protein sacchariferous feed after dehydration, drying;
Fermentation temperature is controlled at 30～35 ℃ in step D, and fermentation time is 30 hours.
In step C with in milk of lime or the lime and the pH value of isolated liquid be 7～8, the pH value after clarified solution and solid matter are puddled is 6～7.5.
In step B: the solid-liquid mass ratio is 1: 3, and temperature is 100-120 ℃, and the dilute sulfuric acid mass percent concentration is 0.4～3%, and hydrolysis time is 120 minutes.
Advantage of the present invention and good effect are as follows:
(1) solves realistic problems such as feed source, market is in short supply, valency height.
(2) make full use of plant or waste crop materials, the manufacturing concentrated feed of turning waste into wealth.
(3) can save food in a large number.
(4) can improve the utilization rate of the many nutritions in the feed and domestic animal absorptivity to feed.
(5) can reduce feed price significantly, promote the fast development of aquaculture with this.
