Description
Technical field
The present invention relates to rumen protected methionine and production method thereof.
Background technology
Methionine is the essential amino acid and first limiting amino acid of cow producing milk.Methionine content is generally lower in the general conventional milk cow forage, causes amino acid imbalance or wretched insufficiency in the dairy cow diet, causes the feed protein utilization rate low, and content of milk protein descends.Directly add common methionine in dairy cow diet, because the effect of rumen microorganism, most of methionine of interpolation is degraded in cud, can not arrive small intestine.So not only do not reach the effect of adding methionine, also can cause the waste of methionine.Unique way of dealing with problems is that the amino acid that is added is carried out rumen-protected processing, and it is not degraded in cud, directly arrives small intestine and is absorbed and used.In dairy cow diet, add through the methionine (rumen bypass methionine) that overprotection is handled and to make amino acid balance more in the chyme that arrives small intestine; thereby improve the utilization rate of dietary protein; save protein feeds; reduce production costs; improve milk production of cow and content of milk protein; and then improve the economic benefit that milk cow produces, and reduce the discharging of nitrogen in the fecaluria simultaneously, have important function to reducing environmental pollution.
At present, the rumen-protected processing of methionine mainly contains chemoproection and two kinds of methods of physical protection.
The major product that adopts the chemoproection method to produce has methionine hydroxy analog and methionine metallo-chelate.Methionine hydroxy analog (MHA) and calcium salt (MHA-Ca) thereof are to develop the product with rumen bypass methionine function of morning, comparative maturity.MHA is the dark brown thick liquid, and the special odor of sulfide and extremely strong acidity are arranged, and pH 1～2.MHA does not degrade in cud, is absorbed at duodenum, in liver and kidney, is converted into the L-methionine and is utilized by body under the effect of amino acid oxidase, D-amino acid oxidase and glutamic-pyruvic transaminase.Because MHA is a liquid, and very strong corrosivity is arranged again, and is in use very inconvenient.MHA-Ca is on the basis of MHA, through with the neutralization of calcium hydroxide or calcium oxide, dry, the solid pulverizing, make after the screening, convenient than MHA in the use.Because also do not have homemade goods on the China market at present, the imported product price is higher, in producing, China milk cow seldom uses.
The methionine metallo-chelate is to make methionine and some metal ion that huge legendary turtle be taken place to close reaction, and methionine and metal ion huge legendary turtle are lumped together, and reduces the degraded of methionine in cud with this, and studying more at present is zinc methionine.But because the chemical bond that methionine combines with metal ion in the methionine metallo-chelate is very insecure, it is undesirable therefore to cross the cud effect, and unstable.In addition, because animal is higher than requirement to metallic element far away to the requirement of methionine, if therefore adopt this method to replenish methionine, when methionine is satisfied the demand, must causes the seriously excessive of metallic element, even metal poisoning takes place to ruminant.
The physical protection of methionine mainly be adopt do not degrade at ruminant tumor gastric, to be at abomasum and the digestible material of small intestine that packaging material wraps methionine processed; thereby make methionine can pass through cud as core; and in abomasum and small intestine, discharge, digested and assimilated.Packaging material commonly used has dystectic fat (acid), fatty acid calcium and high molecular polymer etc.At present, handling existing problem with fat (acid) packaging material mainly is that the technology that adopted is unreasonable, methionine content is lower, bag is by inhomogeneous and incomplete, thereby it is relatively poor to cross the cud effect, and the physical aspect of product is also undesirable, particle is bigger, and inhomogeneous, can not suitability for industrialized production, also inconvenience is used aborning.It is fine to be with high molecular polymer that methionine that packaging material is handled is crossed the cud effect, and the product methionine content is also higher, but the cost of packaging material is higher, complex process, thereby the product price height of producing, and economic feasibility is poor; In addition, some high molecular polymers itself are not had a trophic function, are not easy to be absorbed by animal.
