The present invention relates to field of fodder, and in particular to a kind of piglet preparation method of nucleotides corn straw feedstuff high.
Background technology
China's agricultural crop straw yield is high, and major part is reasonably developed, serious waste of resources, directly burns
Serious pollution is caused to environment, after carrying out processing to it, feed can be prepared, obtain rationally sufficiently using, delayed
Energy crisis and problem of environmental pollution are solved.
Zhang Xiaoqian is in its master thesis《A kind of preparation of novel straw biological feedstuff》In one text, using different sides
Method carries out straw feed pretreatment, as a result shows that the effect processed during with 1% dilute sodium hydroxide, 120 DEG C is best；To pre- place
Stalk after reason carries out proteolysis assay, and stalk is converted using cellulase and zytase complex enzyme, it is determined that optimal enzyme
Solution condition is temperature 50 C, pH 7, enzyme addition 25U/g, solid-to-liquid ratio 1:10, shaking speed 140rpm, enzymolysis efficiency is optimal, this
When reduction candy output be 0.33g (1g stalks).But there is a problem of that conversion ratio is low, nutrition is single.
The present invention destroys the cell wall structure of maize straw by the preprocess method of thermophilic digestion, hence it is evident that improve jade
The hydrolysis result of rice stalk；Immersion treatment is carried out to it with dilute NaOH solution again, maize straw constituent content and crystal is changed
Structure, is conducive to follow-up proteolysis assay.Stalk is converted using cellulase, reduced sugar, cellulose, half are obtained after conversion
Cellulose etc., the method using after fermentation is first digested, improves protein content, is prepared for composite stalk feed.With brewer's yeast
It is raw material, the method being combined using high-pressure homogeneous, enzyme process, broken yeast cell wall produces nucleotide feed high, nucleotides high
Feed Energy significantly improves the growth performance of piglet.

After 2h, with water washing is distilled 3-5 times, gained sample is dried at 60-80 DEG C, stand-by；
B. by after resulting material in a and urea, dusty yeast mixing and ball milling 1-2h, 1:15-20 is added to the citric acid that pH is 4-5
In buffer solution, in 120-130 DEG C of sterilization treatment 20-40min, 1 after cooling:10-15 adds cellulase, adjust pH for it is neutral,
At 50-60 DEG C after enzyme digestion reaction 10-15h, add and produce flesh Candida, ferment 5-10h under normal temperature, obtains degrading maize straws；
C. to running water is added in brewer's yeast, the yeast cream of 30-40% is made into, 60-80MPa is high-pressure homogeneous 3-5 times, is adjusted
PH is 5-6, adds papain, 50-60 DEG C of water-bath self-dissolving 6-8h, centrifugation, enzyme-deactivating, spray drying；
D. dregs of beans is ground, crosses 60-80 mesh sieves, puffing material is made by screw rod bulking machine, by itself and gains in b, c
After material is mixed, appropriate distilled water is shone in spray, and feeding pelleter is conditioned, granulation, and re-dry, cooling are made pellet.
Wherein, the concentration of NaOH solution is 1-2% in step a；In step d when moisture addition is 15-25%, corn stalk
Stalk pellet ratio of briquetting is preferable.
Reaction mechanism of the invention is as follows：
（1）The cell wall structure of maize straw is destroyed by the preprocess method of thermophilic digestion, hence it is evident that improve maize straw
Hydrolysis result；Immersion treatment is carried out to it with dilute NaOH solution again, the constituent content and crystal structure of maize straw is changed,
Be conducive to the carrying out of follow-up proteolysis assay.
（2）Stalk is converted using cellulase, reduced sugar, cellulose, hemicellulose etc. is obtained after conversion, using elder generation
The method for digesting after fermentation, improves protein content, is prepared for composite stalk feed.
（3）With brewer's yeast as raw material, the method being combined using high-pressure homogeneous, enzyme process, broken yeast cell wall, production
