Description
Technical field
The present invention relates to formulation art, more specifically, relate to the coating material for rumen-bypass amino acid preparation and rumen-bypass amino acid preparation thereof.
Background technology
At present, amino acid whose rumen-protected process mainly contains chemoproection and physical protection two kinds of methods.
The major product adopting chemoproection method to produce is amino acids metal sequestration thing, such as lysine metallo-chelate.Particularly, lysine metallo-chelate is that lysine and some metal ion generation sequestration are reacted, and by lysine together with metal ion sequestration, reduces the degraded of lysine in cud with this.But the chemical bond combined with metal ion due to aminoacid in amino acids metal sequestration thing is very insecure, and therefore rumen bypass effect is undesirable and unstable.In addition, due to animal to amino acid whose requirement far away higher than the requirement to metallic element, if therefore adopt the method supplement aminoacid to ruminant, the seriously excessive of metallic element must be caused when aminoacid is satisfied the demand, even metal poisoning occurs.The subject matter that chemoprotectant amino acid preparation exists is complex manufacturing, conversion rate of products is low or cost is relatively high.
Amino acid whose physical protection mainly adopt do not degrade at ruminant tumor gastric, at abomasum and the digestible material of small intestinal, to be coating material carry out bag to aminoacid is processed; thus make aminoacid as core by cud; and discharge in abomasum and small intestinal, digested absorption.The material that can be used as coating material has dystectic fat (acid), fatty acid calcium and high molecular polymer etc.The subject matter that the amino acid preparation of physical protection exists is that stability in rumen official post obtains aminoacid and is released in cud, degrades, or excessively bag is caught aminoacid can not obtains abundant emission and absorption in abomasum and small intestinal.
Therefore, a kind of novel coating material for rumen-bypass amino acid preparation of exploitation or a kind of novel rumen-bypass amino acid preparation is still needed, to solve one or more problems existed in prior art.
Summary of the invention
The invention provides a kind of coating material for rumen-bypass amino acid preparation, comprise soya wax, stearic acid, fatty acid, ethyl cellulose and Polyethylene Glycol and pH sensitive agent.
The invention provides a kind of rumen-bypass amino acid preparation, it comprises coating material of the present invention and one or more aminoacid.
The present invention also provides a kind of preparation method of rumen-bypass amino acid preparation, and it comprises:
1) use one or more aminoacid as core; With
2) use coating material of the present invention that core is carried out coating.
The coatings good toughness made for the coating material of rumen-bypass amino acid preparation of the application, intensity is high, rumen-bypass amino acid preparation can be made well to be preserved in cud, simultaneously due to the pH sensitive agent containing synthesis in coatings, make it can stable existence in cud, can decompose rapidly in abomasum, reach the object of aminoacid emission and absorption.
In addition, the production cost of the rumen-bypass amino acid preparation of the application is low, technique simple, be applicable to commercial production.
Detailed description of the invention
The invention provides a kind of coating material for rumen-bypass amino acid preparation, comprise soya wax, stearic acid, fatty acid, ethyl cellulose, Polyethylene Glycol and pH sensitive agent.
In a specific embodiment, the coating material for rumen-bypass amino acid preparation is made up of soya wax, stearic acid, fatty acid, ethyl cellulose, Polyethylene Glycol and pH sensitive agent.
In a specific embodiment, described pH sensitive agent can be calcium carbonate.Particularly, calcium carbonate used in the present invention is different from the commercially available calcium carbonate used conventional in this area, concrete difference is: first, by commercially available calcium carbonate (such as, purchased from Bo Di chemical inc, Tianjin) be crushed to through super micron mill the superfine calcium carbonate that particle diameter is 1-10 micron, then stearic acid is added at 175-185 DEG C of (such as 180 DEG C) digestion 25-30 minute, filter, namely obtain calcium carbonate used in the present invention, it is directly used in the present invention as pH sensitive agent.
