A feeding trial was conducted to evaluate the results of replacing soybean meal (SBM) with other blend plant protein (BP) (rapeseed meal, cottonseed meal and peanut meal) sources on growth, fish body composition, biochemical parameters, non‐specific immune index and gene expression of growth hormone/insulin‐like growth factor‐1 in Yellow River carp Cyprinus carpio. The results showed that the 600 g/kg replacement with BP in diet did not affect the growth performance of Yellow River carp, but the 800 g/kg SBM replacement diet could depress the growth of fish (p < .05). The 800 g/kg SBM replacement diet significantly impacted the superoxide dismutase, malondialdehyde contents, lysozyme, alanine aminotransferase and aspartate aminotransferase activities (p < .05). Fish fed 800 g/kg SBM replacement diet showed lowest insulin‐like growth factor 1 and highest growth hormone level than that of other diets (p < .05). Both gene expression levels of GH and IGF‐I in hepatic showed significant difference among dietary treatments (p < .05), and the lowest GH and IGF‐I mRNA level in liver were found in fish fed 800 g/kg SBM replacement diet (p < .05). In conclusion, no more than 600 g/kg SBM could be replaced by BP in diet of Yellow River carp without adverse effects on the growth performance. However, 800 g/kg SBM replacement with BP in diet inhibited the growth performance, affected some blood parameters and immune response index, and down‐regulated GH and IGF‐1 gene expression of liver in Yellow River carp. Further, GH level in serum was negatively correlated with GH mRNA level in liver; meanwhile, serum concentrations of IGF‐I were positively correlated with hepatic IGF‐I mRNA expressions.

油菜，棉籽和花生粕的组合替代大豆粉在黄河鲤鱼鲤鱼日粮中的应用

进行了一项饲喂试验，以评估用豆粕（SBM）替代其他混合植物蛋白（BP）（油菜粕，棉籽粕和花生粕）来源的生长，鱼体成分，生化参数，非特异性免疫指数的结果和生长激素的基因表达/胰岛素样生长因子-1在黄河鲤鱼鲤鱼。结果表明，日粮中添加BP替代600 g / kg不会影响黄河鲤鱼的生长性能，但800 g / kg的SBM替代日粮可以抑制鱼的生长（p  <.05）。800 g / kg SBM替代饮食显着影响了超氧化物歧化酶，丙二醛含量，溶菌酶，丙氨酸氨基转移酶和天冬氨酸氨基转移酶的活性（p <.05）。饲喂800 g / kg SBM替代饮食的鱼比其他饮食显示最低的胰岛素样生长因子1和最高的生长激素水平（p  <.05）。饮食中，肝脏中GH和IGF-I的基因表达水平均显示出显着差异（p  <.05），而饲喂800 g / kg SBM替代饲料的鱼肝脏中最低的GH和IGF-I mRNA水平（p <.05）。总之，在黄河鲤鱼的日粮中，BP替代的SBM不超过600 g / kg，而对生长性能没有不利影响。然而，日粮中以BP替代800 g / kg SBM会抑制黄河鲤鱼的生长性能，影响一些血液参数和免疫反应指数，并下调肝脏的GH和IGF-1基因表达。此外，血清中的GH水平与肝脏中的GH mRNA水平呈负相关。同时，血清IGF-I的浓度与肝脏IGF-I mRNA的表达呈正相关。
