锰（大米螯合锰Manganese Rice Chelate）作为动物必需的微量元素，在动物生理活动中扮演着重要角色。当动物通过采食摄入锰后，锰元素在肠道内以简单扩散和主动运输等方式跨越肠道屏障，进入机体内环境，随后随血液循环被输送至各个器官。血液中的锰（大米螯合锰Manganese Rice Chelate）主要通过两种途径参与机体代谢。其一，部分二价锰会与 α2 - 巨球蛋白、β- 球蛋白和 γ- 球蛋白紧密结合，形成具有转运功能的转锰素，随着巨球蛋白被机体利用，锰元素也随之被吸收利用。其二，由于锰与铁之间存在着极强的亲和力，部分游离态的锰先被铁氧化酶 I 氧化为二价锰，再与转铁蛋白结合形成复合物，随后被肝脏摄取，参与造血及体内循环等生理过程。在动物的肝脏等器官中，细胞内的线粒体凭借其较强的锰摄取能力，成为了锰元素（大米螯合锰Manganese Rice Chelate）的主要利用场所。已有研究表明，牛、羊等反刍动物肝脏中的锰浓度为 8~12 μg/g，肌肉中的锰浓度为 0.034~0.156 mg/kg，血液中的锰浓度则为 0.023~0.067 mg/L。由此可见，富含线粒体的肝脏、肾脏等器官是动物体内锰元素的主要富集部位，且其锰含量会随着饲料中锰水平的升高而增加。

Mechanism of absorption, distribution and utilization of manganese (Manganese rice chelate) in ruminants
Manganese (Manganese Rice Chelate), as an essential trace element for animals, plays an important role in animal physiological activities. When animals ingest manganese through feeding, manganese crosses the intestinal barrier through simple diffusion and active transport in the intestine, enters the internal environment, and is then transported to various organs with blood circulation. Manganese in the blood (Manganese Rice Chelate) is mainly involved in the body's metabolism through two main pathways. First, some of the divalent manganese will bind tightly to α2-macroglobulin, β-globulin and γ-globulin to form transfermanganese with transport function, and as macroglobulin is used by the body, manganese is also absorbed and utilized. Second, due to the strong affinity between manganese and iron, part of the free manganese is first oxidized by iron oxidase I to divalent manganese, and then combined with transferrin to form a complex, which is then taken up by the liver and participates in physiological processes such as hematopoiesis and internal circulation. In animal livers and other organs, intracellular mitochondria have become the main utilization sites of manganese (Manganese rice chelate) due to their strong manganese uptake capacity. Studies have shown that the concentration of manganese in the liver of cattle, sheep and other ruminants is 8~12 μg/g, the concentration of manganese in muscle is 0.034~0.156 mg/kg, and the concentration of manganese in blood is 0.023~0.067 mg/L. It can be seen that mitochondria-rich liver, kidney and other organs are the main accumulation sites of manganese in animals, and their manganese content will increase with the increase of manganese level in feed.
