The method comprises the following steps of: cutting, alkali hydrogen peroxide treatment, drainage, thermal spray treatment, cooling, enzymolysis, material adding, mixing, block preparation and packing. The method has the advantages that straws are cut, treated with alkali H2O2, drained, thermally sprayed, cooled, added with a cellulose composite enzyme and treated for certain time, trace elements and vitamins are added, the feed is pressed into blocks, and the biological feed can be obtained after packing, so the whole preparation method is simple, high in utilization rate of raw materials, pollution-free, high in production efficiency and energy-saving; the finally formed feed is good in palatability, high in nutritional value and convenient for livestock to eat; and the feed serving as a commodity is stable in quality, and facilitates long-term storage and transportation.
Description
Technical field
The present invention relates to a kind of preparation method of biological feedstuff of stalk, belong to the biological feedstuff of stalk technical field.
Background technology
Stalk comprises the remainder of crops such as wheat, paddy rice, corn, potato class, oil plant, cotton behind the results seed.It is as the topmost crop by-product in rural area, and resource is very abundant, and output is considerable, but can not get reasonable use.In vast rural area, the stalk that is used for cooking feed stripped only accounts for 15%～20%, other more than 80% stalk resource or as the energy or directly burn in the ground, cause resource significant wastage and environmental pollution.In fact, but agricultural crop straw has very big value and potentiality to be exploited.Yet, if with stalk directly as feedstuff, because its quality is thick and stiff; Crude fiber content is up to 35%～40%, and crude protein content low (about 3%) also contains lignin, hemicellulose and silicate etc.; Digestibility low (40%～50%) when utilizing, palatability is poor, is of low nutritive value; Animal feed intake is also very low, thereby has limited the application of stalk as biological feedstuff.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of preparation method of biological feedstuff of stalk, this preparation method be that a kind of preparation technology is simple, raw material availability is high and pollution-free, production efficiency is high, the method for energy savings; The feed good palatability of its preparation, be of high nutritive value, be convenient to domestic animal and search for food, and as its constant product quality of commodity, be convenient to long term storage and transportation.
To achieve these goals, the preparation method of biological feedstuff of stalk of the present invention is a blank, and alkaline hydrogen peroxide is handled, and drains heat painting, cooling, enzymolysis, the reinforced mixing, clamp dog, packing;
Wherein, blank is meant stalk is cut into 10～30 centimetres rectangular;
It is to be to mix in 1: 25～1: 35 by weight ratio with stalk after prescinding and alkaline hydrogen peroxide solution that alkaline hydrogen peroxide is handled, and oxidation processes 14～38 hours;
Drain is to there not being water droplet to drip with the stalk control water after handling through alkaline hydrogen peroxide;
Heat painting is that the stalk after draining was handled under the condition of pressure 1.5～3.5Mpa 1～5 minute;
Cooling is that the stalk slag after the heat painting is placed cooling;
Enzymolysis be with cooled stalk slag under 40～50 ℃, with the cellulose complex enzyme enzymolysis liquid enzymolysis of PH4.8 buffer solution preparation 48～72 hours;
Reinforced mixing is with adding appropriate vitamin, trace element in the dried stalk slag of enzymolysis, and with mixer it is mixed 10～15 minutes;
Clamp dog is with the block-making machine mixed mixture clamp dog moulding of will feeding in raw material;
Packing is with the feed package after the clamp dog moulding.
The alkaline hydrogen peroxide solution that adopts in the alkaline hydrogen peroxide processing procedure be a kind of be that 1%～2% alkaline solution and concentration expressed in percentage by weight are 2%～14%H by concentration expressed in percentage by weight
2O
2Be the solution that 1: 25～1: 35 ratio is mixed by weight ratio.
The consumption of the cellulose complex enzyme enzymolysis liquid that adopts in the enzymolysis process is 10～20IU/g stalk slag.
The invention has the beneficial effects as follows: through stalk being prescinded alkaline H
2O
2After the processing; Drain; Through the spray of stalk heat, cooling, add again and add trace element and vitamin after cellulose complex enzyme is handled a period of time, feed is pressed into piece; Can obtain biological feedstuff after the packing, whole preparation process is simple, raw material availability is high and pollution-free, production efficiency is high, energy savings; Adopt alkaline hydrogen peroxide to handle can to untie between cellulose and hemicellulose and the lignin to alkali labile ester chain, dissolving hemicellulose and a part of lignin expand cellulose; Thereby make rumen fluid be easy to infiltrate, thereby can improve more than the crude fiber digestibility to 50%, increase feed intake 20%～45% simultaneously; The feed good palatability, and find that through check the biological feedstuff of stalk product crude protein content finally obtain is higher than 15%, crude fiber content is lower than 18%; Can be higher than 14MJ/kg; Be of high nutritive value, and be convenient to domestic animal and search for food, and as its constant product quality of commodity, be convenient to long term storage and transportation.Use this method can stalk be converted into commodity, form industrialization management, thereby stalk is effectively utilized; Make between season, interzone forage grass is able to stable market supply; For drylot feeding, Ban She provide sufficient forage grass, ensure grain security, guarantee the stable development of grain-saving type animal husbandry; Promote peasant employment simultaneously, increase income to have remarkable economic efficiency and crucial social benefit.In addition; Can promote the raiser to culture the enthusiasm of domestic animal; And cross also field effect of abdomen through the stalk of domestic animal, help keeping and improving the content of the soil organism, the increase soil fertility; Reduce the excessive pollution that soil is brought of fertilizer amount, this has positive effect for the development China's green agriculture and the ecological agriculture.Utilize straw feed pasture simultaneously, can reduce the wastage and the crop straw burning pollution on the environment of stalk, help keeping ecological balance.
