The compound is formed by uniformly mixing 60-70% rumen-passed lysine, 15-20% rumen-passed methionine and 10-15% rumen-passed fat in weight ratio. Rumen-passed fat is obtained by heating and melting palm oil, cooling and crystallizing high-melting-point fatty acids, drying and pulverizing. The rumen-passed fat contains 1.5% C14:0 (myristic acid), 73.0% C16:0 (palmitic acid), 6.0% C18:0 (stearic acid) and 15.0% C18:1 by weight (oleic acid). The preparation method of the rumen-passed amino acid high-energy compound comprises the following steps: coating lysine and methionine with rumen-passed fat to prepare rumen-passed lysine and rumen-passed methionine, and then mixing with rumen-passed fat in proportion.
Description
The multiple ^ of milk cow Guo Liu Wei Difficult acid high energy/
Technical field
The invention belongs to raise field of feed processing, tool # ^ and a kind of milk cow rumen-bypass amino acid high energy complex.Background technology
Energy and amino acid levels and its stable market supply in feed are to influence Cow product level and the key factor of dairy food quality, are also the research emphasis that ruminant animal nutrition scholar and feed science are come.
Milk cow is in earlier lactating period, and with the continuous rising of the output of milk, energy requirement also gradually increases, although matter food-intake cow postpartum ^ it is cumulative plus, but postpone 6 weeks or so backward as maximum dry food-intake I ^ high relative to lactation.So, before peak period of giving milk（Especially high yield cow), often cause the output of milk to decline because energy is not enough, body weight], ketoacidosis and fatty liver are then caused when serious.The method of the increase concentrated feed consumption generally used in production at present, although the 3 Ι Λ and suitable improve that can improve energy are given milk but such a way often reduces the feeding of roughage and makes daily ration concentrate-roughage ratio change.And essence is thick than too high, efficiency of feed utilization decline is often led to, butterfat percnetage reduction also easily causes slow milk cow acid poisoning, cud, postpartum paralysis, mammitis and other dysbolisms, shorten milk cow utilization periods.
Recent domestic numerous studies show, the energy supply of milk cow can effectively be improved instead of part fine fodder by improving the Dietary fat content fat that traces back, and be to improve cow producing milk performance and reproductive performance, improve body condition and the effective ways of health status.But adding the main lumen fermentations processed of natural oil Occupational, crude fiber digestibility etc. has obvious inhibitory action.And protected fat can keep that aliphatic acid can be broken down into after height indissolubility, Λ abomasumes and small intestine under its acid ox in the weakly acidic pH environment of cud, so that as using energy source, therefore as the study hotspot foretold at domestic sunset in recent years.The rumen-protected method of month purport fat mainly has three kinds：One is, coated with protein envelope, then to use formaldehyde treated by fat；Two be warship hydrogenation treatment or grease smelting technique life/bag and（Hardening）Month purport fat；Three be to use in calcium and the aliphatic acid production fatty tenth of the twelve Earthly Branches.In current cowboying production using it is more be the fatty tenth of the twelve Earthly Branches.Saturation（Hardening）Although month purport fat exploitation is later, many studies demonstrate that, it not only has good rumen bypass characteristic, and available energy is higher than the fatty tenth of the twelve Earthly Branches, is ideal rumen-undegraded fat source.
Traditionally, the rumen microorganism of ruminant can synthesize various amino acid, need not typically be supplemented from feed.But Recent study shows, in many cases, improved because microprotein synthetic quantity is restricted the sour requirement of Huo Fiber bases, milk cow is to some amino acid（Such as lysine, rattan acid）The need for often occur it is restricted.Although stoichiometric(al) between the species of milk cow limiting amino acid, blind limitation, requirement and amino acid etc. asks not fully aware of; but many researchs are fully proved; the limiting amino acids such as propylhomoserin are supplemented in milk cow abomasum and small intestine or rumen protected amino acid is added in feed, the output of milk and content of milk protein of milk cow can be significantly improved.Amino acid ruminally-protected measure mainly has two：One is physics coating , § Valve pH sensitive material embedding amino acid；Two be that derivative, polymer, metallo-chelate of amino acid etc. are produced using chemical method, such as the MHA and Alimet of Monsanto companies of the U.S., the product such as the Mepron of German Degussa companies.Chemical method is suitable only for the methionine of synthetic method production, and the amino acid produced to most of Yi Fa From and enzymatic isolation method then can only be using coating（Bury）Method.So, coating（Bury)
Method be have a extensive future, the rumen-protected effective ways of amino acid that applied widely, processing cost is relatively low, but this method at present also in conceptual phase, in the market there is no finished product.
