反芻動物體內錳元素（大米螯合錳Manganese Rice Chelate）的吸收、分布與利用機制

錳（大米螯合錳Manganese Rice Chelate）作為動物必需的微量元素，在動物生理活動中扮演著重要角色。當動物通過采食攝入錳后，錳元素在腸道內以簡單擴散和主動運輸等方式跨越腸道屏障，進入機體內環境，隨后隨血液循環被輸送至各個器官。血液中的錳（大米螯合錳Manganese Rice Chelate）主要通過兩種途徑參與機體代謝。其一，部分二價錳會與 α2 - 巨球蛋白、β- 球蛋白和 γ- 球蛋白緊密結合，形成具有轉運功能的轉錳素，隨著巨球蛋白被機體利用，錳元素也隨之被吸收利用。其二，由于錳與鐵之間存在著極強的親和力，部分游離態的錳先被鐵氧化酶 I 氧化為二價錳，再與轉鐵蛋白結合形成復合物，隨后被肝臟攝取，參與造血及體內循環等生理過程。在動物的肝臟等器官中，細胞內的線粒體憑借其較強的錳攝取能力，成為了錳元素（大米螯合錳Manganese Rice Chelate）的主要利用場所。已有研究表明，牛、羊等反芻動物肝臟中的錳濃度為 8~12 μg/g，肌肉中的錳濃度為 0.034~0.156 mg/kg，血液中的錳濃度則為 0.023~0.067 mg/L。由此可見，富含線粒體的肝臟、腎臟等器官是動物體內錳元素的主要富集部位，且其錳含量會隨著飼料中錳水平的升高而增加。

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.
