摘　　要：以初始平均体重为(112.21±0.73)g的卵形鲳鲹(Trachinotus ovatus Linnaeus)为研究对象,进行为期70d的摄食生长试验,研究不同添加水平的发酵豆粕和不发酵豆粕对卵形鲳鲹摄食生长的影响。试验共配制8种等氮等能的饲料,其中以全鱼粉饲料为对照组(饲料1);豆粕取代饲料主要以鱼粉和豆粕为蛋白源,其中,发酵豆粕分别替代17.6%、31.4%、45.1%和60.8%的鱼粉蛋白(饲料2～5),普通豆粕蛋白分别替代17.6%、31.4%和45.1%的鱼粉蛋白(饲料6～8)。结果表明,饲料中不同水平的豆粕替代量对卵形鲳鲹的成活率和摄食无显著影响(P>0.05),但当豆粕蛋白替代鱼粉蛋白达到45.1%时,会显著降低卵形鲳鲹的特定生长率、饲料转化率和蛋白质效率(P<0.05)。饲料中用发酵豆粕蛋白替代鱼粉蛋白达到60.8%时,也显著降低卵形鲳鲹的增重率、饲料利用率(P<0.05)。但是与豆粕替代组相比,在45.1%的鱼粉蛋白替代水平下,发酵豆粕组的增重率和饲料利用率显著高于普通豆粕替代组(P<0.05)。This study was conducted to investigate the effects of partially replacing fish meal in the diets with unfermented and fermented defatted soybean meal（FSBM）on feed intake, growth and feed utilization of juvenile Pompano （Trachinotus ovatus Linnaeus ）.Eight isonitrogenous and isocaloric diets were formulated in which FSBM protein replaced 0 %, 17.6 %,31.4 %,45.1% and 60.8 % fish meal （FM） protein （diet 1 - 5）;USBM protein replaced 17.6 %,31.4 % and 45.1% FM protein （diet 6 - 8）.At the end of the feeding trial,the fish fed the diets containing 37.0 % USBM（replaced 45.1% FM protein）and 44.0 % FSBM （replaced 60.8 % FM protein）had significantly decrease weight gain rate （WGR） and feed utilization than the fish fed the other diets （P 〈 0.05）.Replacement of 45.1% FM protein with FSBM resulted in better values for final weight,weight gain rate and feed utilization than that replaced the same FM protein with USBM.
