利用天然矿物与岩石制作配合成混合饲料添加剂,不仅可以节约粮食,还能起到添加剂等作用,国外早在本世纪初即已开发利用天然矿物饲料资源并进行工业生产和推广使用。美国是最早利用的国家,现已能生产添加剂几十种,配合饲料上千个产品,年产量已逾1亿吨。日本配合饲料年产量达1000万吨。目前,许多国家已成功地用多种非金属矿物配制成含有铁、铝、硅、钙、磷等10多种微量元素的矿物漂浮鱼饲料。饲料矿产是指天然的矿物和岩石,包括金属与非金属固体矿产。目前,国内外饲料矿产有50种以上,如石灰岩、大理石、白云岩、
The use of natural minerals and rock to produce compound feed additives can not only save food but also play an additive role. As early as the beginning of this century, foreign countries have developed and utilized natural mineral feed resources and carried out industrial production and promotion. The United States is the earliest use of the country, is now able to produce dozens of additives, with feed products on the thousands, the annual output has more than 100 million tons. Japan with feed annual output of 10 million tons. At present, many countries have successfully used a variety of non-metallic minerals formulated into a mineral floating fish feed containing more than 10 kinds of trace elements such as iron, aluminum, silicon, calcium, phosphorus and so on. Feed minerals are natural minerals and rocks, including both metallic and non-metallic solid minerals. At present, there are more than 50 kinds of feed minerals at home and abroad, such as limestone, marble, dolomite,
