Description
Technical field
The present invention relates to field of animal feed, and in particular to a kind of sustained release of film coating type ruminates the non-protein of raising
Nitrogen source and preparation method thereof.
Background technology
With developing rapidly for whole world animal husbandry, the not enough contradiction of protein feeds, as the restriction world
The bottleneck of various countries' animal husbandry development.China also faces the critical shortage of protein feeds, and the year two thousand twenty is arrived by short albumen according to estimation
48,000,000 tons of matter feed, the urea of China's feed in animal husbandry year usage amount is also more than 200,000 tons.
Urea is common Nonprotein nitrogen feed raw material, can be directly appended to forage feed ruminant, but by numerous
Limitation：1st, amount of urea is not to be exceeded the 1/3 of total nitrogen requirement, no more than the 1% of diet dry substance；2nd, because of urea good hygroscopicity,
Easily it is decomposed into ammonia, therefore can not be drunk water within 2 hours after feeding, it is impossible to individually feeding or soluble in water is fed；3rd, urea palatability is poor, preferably adds
Feeding or the mineral feed such as same starchy feed, salt are made urea mineral feed and lick brick in mixed concentrate, are licked for ox,
Reduction intake speed；When urea feeding the 4th, is added in feed, it is impossible to while feeding raw soya-bean cake, because containing urase in raw soya-bean cake, having
Urea is decomposed acceleration in the case of water, cause damage.Therefore, urea is difficult to be directly appended to forage feed.
It is a kind of substitute of Nonprotein nitrogen feed to be gelatinized urea, after urea and the high starch-based grains crushed uniformly are mixed
It is expanded to be extruded from, also add a certain amount of adhesive, sustained release agent or additive etc. wherein sometimes different types of to be made
Product.The process of urea is gelatinized by controlling production temperature, the gelatinization degree of adjustment product realizes slow release effect.But, paste
Change urea can not meet ammonia release and utilize holding synchronous with ammonia, while failing to solve palatability problems.
Shanghai U.S. agriculture biology discloses a kind of feed slow-release carbamide and preparation method thereof in patent CN104705535A.Its
Mainly use sustained release agent（Acetic acid hydroxamic acid or sodium tetraborate）As film coating liquid, coating prepares slow-release carbamide in fluid bed
, slow-release carbamide prepared by this method has good palatability and slow release effect, but cost is too high, and sustained release agent material is in itself
It is non-verified.
Coated urea can in slow/controlled release urea nitrogen release, while greatly reducing nitrogen loss, reduce using time
Number, improves efficiency.Mainly have that organic matter is coated and inorganic matter is coated, wherein organic coated urea, refer to coating material it is main into
It is divided into organic matter, mainly there is natural products and its simple extract, such as tung oil, rosin, stearic acid；Synthesize high polymer material,
Such as polyethylene, polystyrene, polyacrylic resin, phenolic resin；Natural macromolecular material, such as natural rubber, shellac, fiber
Element etc.；Semi-synthetic high polymer material, such as ethyl cellulose, methylcellulose.Organic matter is coated because coating material is various, control
Function admirable etc. is released, the research and development direction of coated urea is had become.The coating solution prepared using organic solvent is not only
Cost is high, and exists and fire risk, using being restricted.
Chinese patent CN 101255069B disclose a kind of method that polymeric membrane parcel prepares slow-release carbamide.Its is main
It is to use first to prepare uniform coating liquid with polystyrene and dichloromethane, then, fluidized bed coating urea, then prepared with paraffin bag
Obtain slow-release carbamide.This method nitrogen content is high, and cost is low, and fertilizer is only can be used as because being coated with polystyrene.
