Abstract: Potassium and magnesium are indispensable minerals in the growth process of swine. Potassium ions can maintain the acid ? base balance，ion balance，water balance and osmotic pressure balance of cells，and magnesium ions play an important role in sugar metabolism，protein metabolism and fat metabolism. Dietary addition of minerals can improve growth performance and regulate meat quality of swine. In this paper，the effects of dietary potassium and magnesium supplementation on the growth，reproductive and immune performance in swine were reviewed，and the effects of potassium and magnesium on the quality of pork and its regulatory mechanism were discussed in depth，in order to provide theoretical support for the rational application of potassium and magnesium in swine production.

Key words: Potassium and magnesium, Swine, Production performance, Pork quality

摘要： 钾镁元素是生猪生长过程中不可或缺的矿物质元素。钾离子可维持细胞的酸碱平衡，离子平衡，水平衡以及渗透压平衡，镁离子则在糖代谢、蛋白质代谢及脂肪代谢中发挥重要作用。日粮添加矿物元素可改善猪生长性能并调控肉品质。该文综述了日粮添加钾镁元素对猪生长性能、繁殖性能和免疫性能的影响，同时深入探讨了钾镁元素对猪肉品质的影响及调控机制，以期为钾镁元素在生猪生产中的合理应用提供理论支持。
