Problems solved by technology

[0007] However, although the bioavailability of amino acid complexed (chelated) trace elements synthesized by lysine, methionine, glycine, etc. with higher prices is higher, its use cost is also relatively high, especially in the current highly competitive feed market. Under the environment, the need to reduce the cost of use is increasingly prominent

Abstract

The invention relates to a complex, and specifically relates to a complex of twice-complexed zinc, as well as a preparation method and a usage thereof in animal feed additives. The complex of the twice-complexed zinc is prepared by the following steps of complexing zinc by using sucrose; complexing zinc ions in sewage and filter residues by using amino acid so as to ensure full reaction of the zinc ions; and finally, mixing the sucrose zinc product with the amino-acid-complexed zinc product. The complex of the twice-complexed zinc prepared by the preparation method has the advantages of sucrose zinc, namely low cost and obvious growth-promoting effect, as well as the advantages of the amino-acid-complexed zinc, namely high biological potency, stable chemical properties and good palatability. Compared with single use of amino-acid-complexed (chelated) trace element, the usage cost of the complex of the twice-complexed zinc is reduced by 30-40%.

Description

technical field [0001] The invention relates to a complex, in particular to a secondary complex zinc complex, a preparation method and an application in animal feed additives. Background technique [0002] Zinc is an essential trace element for animals. It is not only necessary to maintain the growth and development of animals, but also the key to the normal development of the animal immune system and the maintenance of immune functions. Zinc is a component or activator of various enzymes in animals, including alkaline phosphatase, carbonic anhydrase, alcohol dehydrogenase, lactate dehydrogenase, glutamate dehydrogenase and carboxypeptidase, etc. Zinc and Ribonucleic acid, deoxyribonucleic acid, and protein biosynthesis are closely related, and zinc is also a component of insulin. When animals are deficient in zinc, they manifest as loss of appetite and growth retardation, followed by incomplete keratinization of the skin. Zinc deficiency also affects the development of ani...
