Supplementation of pelleted feeds (30% crude protein) consisting of practical ingredients with 250, 375 and 500 mg Cholymbi/kg diet resulted significantly improved the growth of common carp, Cyprinus carpio. Highest final average weight was recorded with diet containing 500 mg Cholymbi/kg. Feeding Cholymbi to fish showed increased carcass protein and fat. Gut protease and hepatopancreas amylase activity were the highest with 500 mg Cholymbi/kg incorporated diet (T3). The results of the present study suggest that Cholymbi, a non-hormonal growth promoter could be effectively used in the diet of common carp. Further investigations are required to work out the optimal dosage required in the diet of common carp.
用实际成分组成的颗粒饲料（粗蛋白含量30%），分别添加250、375和500毫克/千克日粮的Cholymbi，显著提高了鲤鱼（Cyprinus carpio）的生长性能。日粮含500毫克/千克Cholymbi时，最终平均体重最高。给鱼类投喂Cholymbi可使鱼体蛋白质和脂肪增加。日粮添加500毫克/千克Cholymbi（T3组）时，肠道蛋白酶和肝胰腺淀粉酶活性最高。本研究结果表明，非激素生长促进剂Cholymbi可有效用于鲤鱼日粮。需要进一步研究以确定鲤鱼日粮所需的最佳剂量。
