Organic zincThe method of zinc supplementation can be to add inorganic zinc or organic zinc to the feed. Inorganic zinc mainly includes zinc sulfate, zinc oxide, zinc carbonate, etc. Organic zinc refers to the complex or chelate formed by organic ligands, such as zinc gluconate, zinc methionine, etc. The utilization rates of different forms of zinc in the body are also Different, generally speaking, the biological potency of inorganic zinc is lower than organic zinc, and organic zinc is lower than amino acid chelated zinc.
Organic zinc refers to the complex (such as zinc glucate) or chelate (such as zinc methionine) formed by zinc and organic ligands. Amino acid zinc Chelates have become the main development trend of trace element zinc additives today.
Characteristics of organic zinc:
① It has good chemical stability and biological stability, which is beneficial to gastrointestinal absorption.
② It is absorbed through the pathway of amino acids or small peptides through “pinocytosis”, which has the characteristics of fast absorption and difficulty in saturation.
③ It can avoid mutual resistance between metal elements during the absorption process, and its absorption utilization rate is as high as more than 70% (the biological utilization rate of inorganic zinc does not exceed 11%).
④ Eliminates the toxic side effects and gastrointestinal irritation of chemical inorganic zinc and organic zinc on the human body. The safe dosage is 300 to 400 times that of zinc sulfate. .
The matrix of organic zinc itself is a very good nutrient, and the protein content in dry yeast can reach 40 %~50%, rich in essential amino acids and reasonable ratio. Yeast is an excellent source of B vitamins. In addition, yeast cells contain a-amylase, protease, hemicellulase, phosphatase, etc. It has many important physiological functions for the human body, such as enhancing immunity, promoting growth and development, improving appetite, and improving dark adaptation ability.
