本试验旨在研究挤压豆粕（SBM）、挤压全脂大豆（FFSB）和玉米蛋白粉（CGM） 3种植物蛋白源完全替代鱼粉（FM）对尼罗罗非鱼（Oreochromis niloticus）和伽利略罗非鱼（Sarothrodon galilaeus）生长和饲料利用的影响。配制4种等氮（约28.0%）和等热量（约19 MJ kg(-1)）试验饲粮。对照饲粮（饲粮1）以鱼粉为主要蛋白质来源。饲粮2 ~ 4均为鱼粉对照饲粮，全部用鱼粉（饲粮2）、鱼油酵母（饲粮3）和鱼油酵母（饲粮4）代替。在植物蛋白饲粮中添加l -赖氨酸和dl -蛋氨酸，以满足罗非鱼的营养需求。每组分配3个网栏，饲喂17周。对照组饲料中尼罗罗非鱼的P含量显著高于对照组饲料
This study was designed to determine the effect of complete substitution of fish meal (FM) by three plant protein sources including extruded soybean meal (SBM), extruded full-fat soybean (FFSB) and corn gluten meal (CGM) on growth and feed utilization of Nile tilapia Oreochromis niloticus and tilapia galilae Sarothrodon galilaeus. Four isonitrogenous of crude protein (ca. 28.0%) and isocaloric (ca. 19 MJ kg(-1)) experimental diets were formulated. The control diet (diet 1) was prepared with FM as the main protein sources. Diets 2-4, each FM control diet, were completely substituted with SBM (diet 2), FFSB (diet 3) and CGM (diet 4). L-lysine and DL-methionine were added to plant protein diets to cover the nutritional requirements of tilapia. Each treatment was allocated to three net pens and fed for 17 weeks. Nile tilapia fed the control diet showed significantly higher (P
