Description
Technical field
The present invention relates to a kind of complex compound, particularly a kind of complex compound of secondary complexing zinc, preparation method and its in animal
Purposes in feed addictive.
Background technology
Zinc be animal necessary to trace element, be only maintain animal body grow institute it is required, and be also animal
Immune system normal development, the key for maintaining immunologic function.Zinc is the constituent or activator of a variety of enzymes in animal body, bag
Alkaline phosphatase, carbonic anhydrase, alcohol dehydrogenase, lactic dehydrogenase, glutamte dehydrogenase and carboxypeptidase etc., zinc and ribose core are included
The biosynthesis of sour DNA and protein has the constituent of close ties, zinc or insulin.When animal zinc-deficiency
When show as anorexia, growth retardation, the incomplete angling of skin occurs therewith, zinc-deficiency has an effect on Bone Development for Animals and make length
Bone malformation, poultry propagation function reduction, hatching of breeding eggs rate reduce etc., and the proper splitting of animal immune cell during zinc-deficiency, point
Change is also suppressed, and the activity and quantity of immunocyte are greatly lowered, protein biosynthesis block, so as to damage the immune of body
Function.Rational zinc level can strengthening immune system, resistivity of the enhancing animal to disease.Geng Ailian etc. (1997), which is used, contains zinc
39.5th, 121.5,151.5,181.5,211.5 and 891.5mg/kg Diet Hai Lanbai laying hens, found through 10 weeks, with
The raising of feed zinc level, the content of serum globulins significantly improve, and high zinc group serum IgG, IgM, IgA content dramatically increase.
Many researchers think that suitable zinc amount can increase animal appetite, strengthen antioxidant ability of organism, promote pancreas islet
The synthesis and secretion of plain and IGF etc., so as to strengthen anabolism, promote breeding performonce fo animals.Xu Zirong etc.
(2001) report that Pharmacological Level of Zinc is seemingly a kind of group effect to the growth promoting function of pig, on the one hand adopted by improving a poor appetite, improving
Appetite and feed digestibility and promote to grow；On the other hand, by removing interior free yl, immunity is improved, in genetic transcription
Level strengthens the synthesis of some zymoproteins, promotes the synthesis and secretion of insulin, strengthens anabolism and promotes growth.
It is abnormal that male animal zinc-deficiency can cause convoluted seminiferous tubule epithelial cell structure to occur, cause gonad development and function by
Damage, Sperm specific enzyme are obstructed, and sexual desire declines；Dam zinc-deficiency can cause ovarian atrophy, and the oestrous cycle is disorderly, postpone heat or do not send out
Feelings, embryonic development is abnormal, death rate increase, difficult labour, stillborn foetus and malformation fetus increase.Rational Zinc supplementation can improve animal
Reproductive performance.
High zinc (especially zinc oxide), it is most of to be excreted to excrement in environment, it can cause environment pollution.Canadian state
The maximum addition of zinc in daily ration is defined as 500mg/kg by feed association of family.Organic zinc particularly zinc-amino acid chelate, such as
Zinc methionine acts on trace element necessary to growth of animal with amino acid, Chelating state chemical combination of the synthesis with cyclic structure
Thing, it is a kind of micro element supplement agent close to natural form in animal body.Compared with inorganic zinc, have efficient, less toxic, low
The features such as polluting, easily absorbing.Simultaneously as different tissues and enzyme system need ratio and quantity to certain amino acid in animal body
Difference, therefore by chelating the zinc of specific amino acids or peptides, you can increase corresponding Zn-ef ficiency and transport each specific group
Knit and the chance (Fang Luoyun, 2001) in enzyme system.Studies have reported that zinc methionine is improving animal immunizing power, improve animal
Production performance, the significant effect for improving product quality etc. are higher than inorganic zinc (Wang Gang, 2006).But zinc-amino acid chelate is given birth to
Production. art is relative complex, and cost is higher, and its cost is in a ratio of 6-8 with inorganic zinc：1, limit popularization and application in production.So
And from the aspect of input-return rate, 18 times higher than inorganic zinc or so of zinc-amino acid chelate (meter peak etc., 2001).
But with the development of feed industry and the feed addictive such as the progress of aquaculture, trace element, amino acid into
For the indispensable raw material of mixed feed.People add various dose according to different animals nutritional need in mixed feed
The feed addictives such as trace element, amino acid carry out balanced nutrients composition, promote animal productiong, improvement product quality to reach, carry
High feed conversion rate, reduce feeding cost, the purpose increased economic efficiency.
However, amino-acid complex (chelating) trace element with synthesis such as the higher lysine of price, methionine, glycine
Although biological value is higher, its use cost is also of a relatively high, especially under current feed market environment with keen competition, drop
The demand of low use cost increasingly highlights.
Therefore, inventor is first complexed zinc with maltose, the zinc then not reacted completely with amino-acid complex again, both reduces
Cost, moreover it is possible to keep certain biological value.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
