锌元素是动物生长发育过程中所必需的微量营养元素  ，但因动物体内不能生成,故需要额外补充满足机体需求  ，锌在机体生长发育中具有多种重要功能,作为许多酶和激素的组成部分,包括碳酸酐酶、DNA聚合酶、RNA聚合酶、乳酸脱氢酶、碱性磷酸酶、逆转录酶以及超氧化物歧化酶等含锌酶,如碳酸酐酶在蛋壳形成中提供关键的碳酸氢盐离子,保证骨钙储存 。同时,动物机体对锌元素的吸收通过增强锌转运蛋白和金属硫蛋白的基因表达,也可提高老蛋鸡蛋壳强度和体液免疫力 。此外,在动物生产中锌还具有其他生理功能,如改善生长性能、胴体产量和肉质、生产和生殖性能、肠道健康等  ，与此同时,通过补锌可通过激活keap 1/N rf 2抗氧化信号通路,提高动物抗氧化能力、免疫力和抗氧化酶相关基因的表达 。

Biological function of zinc ascorbate and its application in animals

Zinc is a necessary micronutrient element in the growth and development of animals, but because it cannot be produced in the animal, it needs to be supplemented to meet the needs of the body, zinc has a variety of important functions in the growth and development of the body, as a component of many enzymes and hormones, including carbonic anhydrase, DNA polymerase, RNA polymerase, lactate dehydrogenase, alkaline phosphatase, reverse transcriptase and superoxide dismutase and other zinc-containing enzymes, such as carbonic anhydrase provides key bicarbonate ions in the formation of eggshells to ensure bone calcium storage. At the same time, the absorption of zinc by the animal body can also improve the eggshell strength and humoral immunity of old eggs by enhancing the gene expression of zinc transporter and metallothionein. In addition, zinc also has other physiological functions in animal production, such as improving growth performance, carcass yield and meat quality, production and reproductive performance, intestinal health, etc., at the same time, zinc supplementation can activate the KEAP 1/N RF2 antioxidant signaling pathway, improve animal antioxidant capacity, immunity and the expression of antioxidant enzyme-related genes.
