Description
Technical field
The present invention be more particularly directed to of the application of a kind of zinc glutamate or derivatives thereof, belong to field of fodder as animal feed additive for promoting growth.
Background technology
Zinc participates in the multiple metabolic response in the body as one of animal body trace elements necessary, and growing of animal played an important role.The total content of zinc is about 30ppm in the intact animal body, and it is 100ppm that pig starter feed zinc requirement is recommended by American National research council (NRC), and pig is very strong to the tolerance of zinc, can reach 20~30 times of normal needs.It is reported, add 3000ppm zinc oxide in the daily ration and can significantly improve ablactation stress piglet body weight, average daily gain and daily ingestion amount, reduce material anharmonic ratio and wean back diarrhea rate, effectively prevent stress of baby pigs caused ablaction syndrome.Studies show that the action effect of zinc and its interpolation form have certain relation, in the diet of weanling pig, add 200~500ppm organic zinc growth promotion effect and be equivalent to 2000~3000ppm zinc oxide.Along with the generally use of high zinc daily ration, people begin to pay close attention to high dose zinc to the toxic and side effect of body and to the pollution problem of environment.When zinc overdose, cause the wasting of resources on the one hand, cause body to poison on the other hand, and also exist complicated antagonism between zinc and copper, the iron, any in daily ration the change of content may influence the absorption of other elements and cause that it does the variation of character mutually, even can have influence on the change of whole machine body physiological situation.
Three phases has been experienced in the zinc source exploitation of feed.The zinc source of Tian Jiaing is an inorganic zinc the earliest, as zinc oxide, alkali formula glycine zine etc.A large amount of researchs are thought, high dose zinc oxide can promote periglottis taste bud cell to regenerate rapidly, modulation of appetite, the growth of some harmful bacteria of inhibition enteron aisle and food and extend are in the alimentary canal time of staying, guaranteed nutriment digesting and assimilating at enteron aisle, reduce the fermentation of large intestine microorganism and effectively suppressed grice diarrhoea, thereby improved daily gain.Hill and Cromwell (1996) studies show that high zinc (3000ppm zinc oxide) daily ration level has facilitation to growth in piglets.Find that subsequently the organic mineral salt is more easily absorbed by animal and utilizes, this mainly comprises zinc gluconate, zinc citrate etc.Organic zinc more approaches the action mode in the body, and biological value will be higher than inorganic zinc.Organic zinc is stable existence in alimentary canal, can not form with other materials and hinder the compound that absorbs, and can change into the form with biological function then more effectively by intestinal villi transporte to cells epithelium.
Novel third generation zinc element additive mainly is a zinc-amino acid chelate, comprise glycine zine, zinc methionine and lysine-zn etc., it has good biochemistry stability, because it is positioned at the metal ion with five-membered ring or six-membered ring chelate center and can passes through the intestinal villi brush border, therefore easily absorb for animal, have no side effect and biological value is higher than inorganic zinc, become a kind of comparatively desirable feed addictive.But the network of different amino acid ligands (chela) closes zinc, and addition differs greatly because of the zinc source is different because the character of part differs, and the inorganic zinc addition is higher, and the organic zinc addition is relatively low, and piglet is added period generally within 1~4 week after the ablactation.But the zinc source of different aminoacids part has different physicochemical properties, particularly water-soluble, acidproof ability and profit distribution coefficient, because the water-soluble and acidproof ability of compound can influence the absorption dynamics process in the body, suitable profit distribution coefficient is relevant with the antibacterial activity of compound.Though glycine zine and zinc methionine commonly used clinically now want high than the bioavilability of inorganic zinc, but the solubility in its water is high and acidproof ability (seeing the result of the test in the content of the present invention), therefore the existing high bioavilability that can guarantee in its body of desirable zinc-amino acid chelate will have lower water-soluble and stronger acidproof ability in addition and could guarantee that trace element is absorbed and used with the form arrival enteron aisle of organic.
