摘　　要：矿物元素在动物的生长发育、机能维持、产品质量、免疫功能等方面发挥重要的作用。因为矿物元素之间复杂的互作和拮抗关系,单一提高某种矿物元素在动物饲粮中的配比,会导致饲料利用率下降、成本上升、环境污染等问题。在此研究背景下,本文提出了矿物元素理想模式这一全新概念,即在动物的不同生长发育阶段,不同种类矿物元素之间最佳的比例关系,以确保动物能够以经济适宜的添加量获得最佳的生产效益。本文以仔猪为例,进行了矿物元素理想模式的研究与实践,并分析了动物矿物元素理想模式的理论基础和研究意义,指出了确定矿物元素理想模式存在的困难和需要注意的问题。Mineral elements play an important role in the animals＇ growth and development, functional sus- tains, quality of the product, immune function and so on. Because of the delicate interaction and antagonism existing in mineral elements, a single increase of some mineral element in animal feed ratio will lead to the de- cline of feed utilization, wasted cost and environmental pollution. Under this background, a new concept ＇ mineral element ideal pattern＇ was set up in this review, based on the analysis and research for piglets＇ min- eral nutrition. This pattern meant that different kinds of mineral elements were the best quantity proportion rela- tionship, ensuring the best production efficiency acquired from an economic trace minerals adding in the ani- mals＇ different growth stages. Furthermore, the theory foundation and application prospect of the pattern were discussed, as well as some problems of the pattern were pointed out and solutions were given in this review.
