Additive of organic zinc feed and preparation method and use thereof

Abstract

The invention discloses an additive of organic zinc feed and preparation method and use thereof. The method comprises the steps of: stirring under 10 to 60 degrees centigrade, adding chitosan with deacetylation being 70 to 100% into diluted acid with volume percent density being 0.5 to 2% to be 0.5 to 10% chitosan acid solution; then adding inorganic zinc solution into the chitosan acid solution; wherein the content of the inorganic zinc is 1 / 5 to 30 times of the content of the chitosan; reacting for 0.5 to 15 hours, separating, washing the obtained solid substances for many times until checking out the ions free of zinc, drying, crashing to obtain the additive of organic zinc feed. The invention provides a simple method of preparing the additive of organic zinc feed, which has stable quality and is widely popularized and applied. The additive can be used as the additive for zinc for livestock, birds, aquatic animals and experimental animals. The additive has high biological availability and can save sources and protect the environment and can be sued as an immune dose for improving the resistance against diseases of the animals.

Description

technical field [0001] The invention relates to an organic zinc feed additive and its preparation method and application. Background technique [0002] Zinc is an essential trace element for animals. It is closely related to many basic physiological activities of animals and plays an important role in maintaining the health and normal physiological functions of animals. It has been proved that zinc participates in the composition of more than 300 enzymes and functional proteins in animals. It is also found that zinc is closely related to the immune function of the body. It participates in the development of immune organs, affects the performance of specific and non-specific immune functions, and is of great significance in maintaining the normal immune function of the body and preventing the invasion of bacteria and parasites. The physiological and biochemical functions of zinc are very extensive. It not only participates in the metabolism of DNA, RNA, protein, sugar, lipid,...

AI Technical Summary

Problems solved by technology

The use of high doses of zinc usually has the following problems: (1) low absorption

(4) There is mutual antagonism and synergy between the absorption and utilization of zinc, copper, calcium, iron, and selenium in the animal body. Excess or deficiency of any element will affect the normal absorption of other elements, and feed The increase of mineral elements in the body will definitely have a negative impact on the stability of vitamins, resulting in the lack of vitamins

(5) High-dose trace element zinc produces a large number of free radicals in the process of absorption and tissue utilization in the small intestine, causing oxidative damage to cells and seriously destroying the integrity of intestinal cell membranes, resulting in stunted animal growth, reduced feed utilization, and reduced meat quality
