Description

The method using corn stover preparation high nutritive value feed based on steam explosion technology
Technical field
The present invention relates to a kind of manufacturing methods of animal feed, especially a kind of to manufacture high nutritive value using corn stover The method of feed, it is specifically a kind of it is based on steam explosion method, lignocellulosic structure in straw can be changed make it Increase substantially the method using corn stover preparation high nutritive value feed of the digestibility in animal rumens.
Background technique
It is well known that the in short supply of high-quality feed is caused due to factors such as grass-land deterioration, desertifications, and with animal husbandry It rapidly develops, the demand to feed is increasing.The stalk of crops can be widely used as feed, but corn stover exists Palatability is poor, domestic animal grazing rate is low, digestibility and nutritive value be not high, contain harmful substance the deficiencies of, when as feed It will be by corresponding processing.Processing method used at present is only limitted to the modes such as green storage, ammonification, and processing quality is not high, quality Unstable, the effective ingredient in product processed is not fixed, poor to the processing capacity of harmful bacteria and pesticide residue, in product Harmful substance contents are high, exist to cause a disease and infect hidden danger, easily mouldy, rotten, unsuitable long term storage, not readily transportable, small can only advise Mould production.
Physical method, chemical method and Biochemical method side currently can be divided into the common processing technique of straw feed both at home and abroad Method.
These methods and techniques have the advantages that respective, but also have its limitation, not using wherein certain single method Stalk can be fully solved as problems existing for feed.For example, physical method processing can only improve the palatability of straw feed With grazing rate problem, the nutritive value of straw feed can not be improved;Although ammonification can significantly improve the nutrition of straw feed Value, can not but solve the problems, such as that lignin in stalk, cellulose are heavy, exist simultaneously ammonia consumption greatly and be easy to produce ammonia Intoxicating phenomenon;Ensiling mainly solves green straw feed storage problem, is only applicable to corn stover, wheat and rice straw should not be adopted With therefore, using above-mentioned single conventional stalk processing method, stalk cannot being fully solved and be processed into many skills existing for feed Art problem needs to research and develop on the basis of integrating existing stalk processing technique at new straw feed processing Manage methods and techniques.
It is well known that the main component of corn stover is cellulose, hemicellulose and lignin, the quality of these three ingredients Account for the 80%~95% of plant fiber corn stover gross mass.Lignin is combined in the form of covalent bond with hemicellulose, by fiber Plain molecule embedding wherein, forms a kind of natural barrier, and enzyme is made to be not easy to contact with cellulosic molecule.And lignin is non-aqueous Property, the complexity of chemical structure, and make lignin itself and be difficult to degrade.Therefore the presence of lignin and the protection work to cellulose The major obstacles made full use of with stalk resource is become.This distinctive eucaryotic cell structure of corn stover itself prevents it from being ruminated Animal effectively digestibility and utilization.The function of how utilizing ruminant tumor gastric decomposition of cellulose substance, improves ruminant pair The digestibility of corn straw feedstuff is the high-quality straw feed of production, improves the critical issue of corn straw feedstuff nutritive value.Institute To open the tight structure of lignocellulosic by processing, removal lignin is a kind of raising corn to the protective effect of cellulose The effective ways of straw feed nutritive value.
Steam explosion method is a kind of effective means for changing lignocellulosic structure.As far as the applicant is aware, existing at present Changing lignocellulosic structure using steam explosion technology slurrying and using steam explosion method, corn stover prepares ethyl alcohol and biogas turns to improve The relevant report of rate, but have not yet to see the relevant report for being used for preparation high nutritive value feed.
Summary of the invention
The purpose of the present invention is can not change corn stalk fiber element structure for Typical physical, chemical method, therefore make Corn stover it is not high as feed nutritive value, utilization rate is low, wastes big problem, invents a kind of benefit based on steam explosion technology With the method for corn stover preparation high nutritive value feed.
The technical scheme is that
A method of high nutritive value feed being prepared using corn stover based on steam explosion technology, it is characterized in that it includes Following steps:
Firstly, crop stalk is crushed, and it is processed into the strip structure that length is 2-8 centimetres;
Secondly, carrying out chemical pretreatment to the corn stover of smashed strip structure in favor of the softening of fiber, improve Microstructure, convenient for improving the treatment effect of steam explosion;
Strip corn stover Jing Guo chemical pretreatment is fitted into steam blasting device, is passed through saturated vapor, makes by third Steam pressure in demolition set maintains 0.2~3MPa, and the dimension pressure time is 0.2~30min;
4th, opening steam blasting device makes pressure therein carry out abrupt release, is discharged by instantaneous pressure, to reach The purpose of the wood fibre structure of the strip crop stalk in steam blasting device is destroyed, while being made in strip crop stalk Remains of pesticide decomposed, prepare the Filamentous straw feed of high nutritive value and safe without toxic side effect.
The corn stover is the combination of one or more of rice, corn, wheat, beanstalk stalk or peanut straw.
The process for chemically pretreating is conventional ammoniated treatment or composite chemical processing;Conventional ammoniated treatment (including add AMMONIA TREATMENT and plus Urea treatment) after the moisture content of corn stover should control in 30-60%, the time of ammoniated treatment reaction is normal It should be no less than 24 hours under temperature, improving ammonification temperature then can correspondingly shorten the reaction time;The composite chemical is handled Following steps:
Firstly, into strip corn stover be added be equivalent to strip person's crop straw weight 0.2~5% urea and quite In the Ca (OH) 2 of strip crop stalk weight 2~8%;
Secondly, adjusting the moisture content of strip corn stover, it is maintained at moisture content between 30-60%;
Above-mentioned corn stover is stirred evenly to be placed in sealing container under room temperature and be reacted at least 24 hours by third, if Reaction temperature is improved, then can accordingly shorten the reaction time.
Beneficial effects of the present invention:
1, simple process.
2, steam explosion technology is applied to feed preparation field for the first time by the present invention, is a kind of completely new utilization corn stover The method for preparing animal feed, its energy consumption is lower, with strong applicability.
3, it is easy to implement the batch production of feed processing, mechanization, intensive, substantially reduces production cost.
4, after after chemical pretreatment+steam blasting handles corn stover, nutritive value, Er Qieke are not only increased Thoroughly to kill the worm's ovum in stalk, mould and virus, the prevalence of the domestic animals disease generated by feed factor is blocked.Agriculture simultaneously The residual of medicine is decomposed, and realizes the purpose of safe without toxic side effect.
5, become filiform using processing method of the invention treated corn stover, and can be processed into blocky roughage, Crude protein content is increased to 8%~12% from 2%~4%, and digestibility is increased to 65% or more from 30%~45%, Feeding Value It doubles, palatability is good, and feed intake improves 60%~80%.Its nutritional ingredient is equivalent to grassland and produces medium sheep's hay.
