5种植物蛋白源替代鱼粉对花鲈生长性能和消化酶活性影响 　　摘要：选用480尾初始体重为（9.69±0.30）g的花鲈（Lateolabrax japonicus）随机分成6组，分别投喂含40%鱼粉的基础饲料和以23.30%豆粕、22.40%花生粕、23.82%棉粕、27.77%菜子粕、38.98%玉米DDGS等蛋白替代16%鱼粉的5种替代饲料，记作FM、SBM、PNM、CSM、RSM、DDGS。结果表明，与FM组相比，SBM和PNM组增重率、特定生长率和饲料系数无显著性差异（P0.05），RSM组摄食率显著降低（P0.05），各替代组全鱼粗脂肪与FM组相比均显著升高（P　　关键词：花鲈（Lateolabrax japonicus）；植物蛋白源；鱼粉；替代；生长性能；消化酶 　　中图分类号：S965.211 文献标识码：A 文章编号：0439-8114（2014）04-0866-05 　　Effects of Partial Replacement of Fish Meal by Five Plant Proteins on Growth Performance and Digestive Enzymes Activities of Lateolabrax japonicus 　　WANG Guo-xia1，FU Jing-jing1，2，HUANG Yan-hua1，CHEN Xiao-ying1，MO Wen-yan1，CAO Jun-ming1， 　　LI Lin1，2，WU Chun-yu1 　　（1.

The basic diet contained 40% fish meal， and five test diets were prepared with 16% fish meal replacement by 23.30% soybean meal， 22.40% peanut meal， 23.82% cottonseed meal， 27.77% rapeseed meal and 38.98% corn-DDGS （FM， SBM， PNM， CSM， RSM and DDGS）. The results showed that no significant difference was found in weight gain rate （WGR）， specific growth rate （SGR） and feed coefficient （FC） of SBM and PNM groups compared with FM（P0.05）and feeding rate of RSM group was significantly decreased（P0.05）. The whole fish crude lipid content of the replacement groups was significantly increased in comparison with FM group（P 　　Key words： Lateolabrax japonicus； plant protein source； fish meal； replacement； growth performance； digestive enzyme 　　花鲈（Lateolabrax japonicus）又名七星鲈、鲈板，隶属鲈形目科花鲈属[1]，为凶猛肉食性鱼类，因其肉质
