试验设计的颗粒饲料中鱼粉含量为５％，实测粗蛋白含量为２１．６％，试验组矿物质添加量为千分之一．供试的尼罗罗非鱼种（Ｏｒｅｏｃｈｒｏｍｉｓｎｉｌｏｔｉｃｕｓ）平均重量为１４．８ｇ．结果表明，试验组的尼罗罗非鱼种增重效果显著高于对照组（Ｐ＜０．０１），其饲料系数为２．０４；此外，鱼体肌肉组织必需氨基酸（ＥＡＡ）含量及其蓄积率、蛋白质效率等指标亦以试验组的较高，而试验组鱼体肌肉和肝脏的Ｃｕ、Ｚｎ、Ｐｂ、Ｃｄ等重金属含量则明显低于对照组．试验证实，配制的矿物质添加剂对尼罗罗非鱼种生长有显著的促进作用
Experimental design of the pellet feed fish meal content of 5%, the actual crude protein content of 21.6%, the experimental group of minerals added as one thousandth. The average weight of Oreochromis niloticus tested was 14.8 g. The results showed that the weight gain of Nile tilapia in the experimental group was significantly higher than that of the control group (P <0.01), and the feed coefficient was 2.04. In addition, the content of essential amino acids (EAA) The accumulation rate, protein efficiency and other indicators were also higher in the test group, while the experimental group of fish muscle and liver of heavy metals such as Cu, Zn, Pb, Cd were significantly lower than the control group. The experiment confirmed that the formulated mineral additive has a significant promoting effect on the growth of Nile tilapia
