Description
Technical field
The present invention relates to animal feed additive field, be specifically related to a kind of rumen bypass becholine particle and production method thereof.
Background technology
Choline (formal name used at school 2-ethoxy-trimethyl bursine), Cobastab a kind of.Choline can promote liver, the fat metabolism of kidney; The basis of choline or body synthesis of acetyl choline, thereby the transmission of the signal that affects the nerves.Choline is also that in body, methionine synthesizes one of required methyl source in addition.In much food, all contain natural choline, but its concentration is not enough to meet modern feed industry to the mushroom needs of animal, therefore in feed, should adds synthetic choline to meet its needs.Lack choline and can cause fowl poultry fatty liver, poor growth, death the phenomenon such as increases and occurs.
Choline Chloride is the hydrochloride of choline, in general animal grain ration, has been widely used in the nursing of various nonruminants (as chicken, pig, fish etc.), and obtains good effect as animal feed additive.But due to the degradation of ruminant (as milk cow, goat etc.) rumen microorganism to Choline Chloride, Choline Chloride is restricted in the application of ruminating on poultry.Feed grade Choline Chloride has strong moisture absorption, if it is slightly higher to be prepared into feed addictive content with Choline Chloride, product is the moisture absorption very easily, cannot safe storage.If content is too low, animal must eat and just can reach effective dose in a large number.The moisture absorption of Choline Chloride, absorbing carbon dioxide and surface-active action all have strong destruction to supporting one's family in feed, and the Choline Chloride existing with this kind of form enters ruminant tumor gastric, most of meeting is by the microbial degradation in cud, effective percent of pass in cud is extremely low, only have a seldom part just can enter small intestine, can be by intestinal absorption few, therefore directly give ruminant fed Choline Chloride, DeGrain, how to reduce the degradation rate of Choline Chloride in ruminant tumor gastric, can be entered small intestine smoothly and be absorbed, it is the technical problem of being badly in need of solution.
In the prior art, in order to solve an above-mentioned difficult problem, adopt coated form that Choline Chloride is coated with coating material more, avoid its moisture absorption and degrade in cud.CN1561979A discloses a kind of becholine microcapsule, it is capsule material by adding hydrogenated vegetable oil, prepare the rumen bypass becholine microcapsule that effective content reaches 35%～45%wt%, but hydrogenated vegetable oil is a kind of artificial grease that contains a large amount of trans-fatty acids, Time magazine was once announced, hydrogenated vegetable oil is non-existent at nature, that is to say under natural situation, human or animal's body cannot be digested and assimilated this grease, a large amount of hydrogenated edible vegetable oil can be produced injury to body liver, in addition this application finished product is solid cylindrical particle, there is certain length and diameter, and hydrogenated vegetable oil is as dressing, its solid is poor, slightly be subject to the external pressure can deformation fracture, eventually the above, no matter from physics or chemical physical property, the coating material that hydrogenated vegetable oil is all not suitable as rumen bypass product is used in a large number.Two patent applications of CN101269051A and CN102326714A also disclose respectively usings acrylic resin IV and shitosan as the technology of the coated Choline Chloride of coating material and the technology as the coated Choline Chloride of coating material with acrylic resin IV and ethyl cellulose of usining, although above-mentioned two kinds of technology all can effectively overcome Choline Chloride and be degraded in cud, but all adopted expensive coating material, and during preparation, program is complicated, is not suitable for large-scale industrial production.
Summary of the invention
The invention discloses a kind of Choline Chloride particle; its not only content reach 30～35%; and the effective percent of pass in cud surpasses 85%; can be stably transported to digested absorption again after small intestine; it is to have fabulous physical stability that Choline Chloride particle of the present invention also has an advantage, has overcome the shortcoming that the easy moisture absorption of Choline Chloride should not store.
Rumen bypass becholine particle of the present invention, it is spheric granules, and particle diameter is 1.6～3.0mm, and particle skin is vegetable fat, and granule interior is the core core of chloride containing choline, Choline Chloride weight accounts for 30～35% of particle gross weight.
Wherein said vegetable fat is one or more in palmitic acid, stearic acid, myristic acid, oleic acid or linoleic acid preferably.
In preferred plant grease, contain palmitic acid 75%～90%, stearic acid 5%～10%, myristic acid 0%～5%, oleic acid 5%～10% and linoleic acid 0%～3%.
The weight of above-mentioned vegetable fat preferably accounts for 40～60% of particle gross weight.
In core core, except containing Choline Chloride, also contain packing material, preferred packing material is corncob.The weight of corncob preferably accounts for 15～30% of particle gross weight.Can also be containing the hydroxypropyl methylcellulose as adhesive in packing material.
Choline Chloride particle of the present invention is circular granular, and good fluidity is convenient to evenly add in feed.And its anti-moisture sorption effect is good, stable storage.
Evidence is placed in constant-temperature constant-humidity environment 24 hours by rumen bypass becholine particle of the present invention, and its outward appearance is not any change, and mobility of particle is good, and through weighing, calculating its hydroscopicity is only 1～2%.And in contrast, the Choline Chloride particle that we are carrier by equal effective content corncob is placed in the environment of constant temperature and humidity 24 hours, it is softening to there is because of moisture absorption particle in its outward appearance, mutually coheres and grain color such as deepens at the phenomenon, and through weighing, its moisture absorption ratio of calculating is 12～15%.
The preparation method of Choline Chloride particle of the present invention, comprise: Choline Chloride and auxiliary material are dry mixed in high-speed mixing granulating machine, after add adhesive to carry out wet mixing, cutting is prepared content and is reached more than 60% Choline Chloride core core, and core core is put into fluid bed fluidized drying; By cyclone bed side spray method, vegetable fat is carried out to dressing to dry Choline Chloride core slug particle again.
Preferred preparation method comprises:
(1) prepare Choline Chloride particle
Auxiliary material maize cob meal is broken to 60～80 orders, standby.
Get corncob and 75% Choline Chloride liquid and put in high-speed mixing granulating machine and be dry mixed, after add hydroxypropyl methylcellulose to carry out wet mixing as adhesive, the uniform Choline Chloride particle of particle diameter is prepared in cutting.
