本文报告了饲料中添加300mg／Ks和400mg／Kg稀土氨基酸配合物（由稀土蛋氨酸和稀土赖氨酸各50％混合而成），在网箱养鲤应用试验中，实验鲤鱼比对照鲤鱼增重率分别提高6．3％和16％。在虹鳟鱼养殖应用试验中，实验虹鳟鱼比对照虹鳟鱼分别提高11.2％和29．6％。试验结果初步表明：饲料中添加400mg／Kg稀土氨基酸配合物有促进鲤鱼和虹鳟鱼快速生长的作用。
This paper reports the addition of 300mg / Ks and 400mg / Kg of rare earth amino acid complexes (composed of 50% rare earth methionine and rare earth lysine mixed) to the feed. In the experiment of cage carp, the experimental carp gained weight more than the control carp The rates increased by 6.3% and 16% respectively. In rainbow trout farming applications, the experimental rainbow trout increased 11.2% and 29.6% respectively over the control rainbow trout. The preliminary results showed that the addition of 400mg / Kg of rare earth amino acid in the diet could promote the rapid growth of carp and rainbow trout.
