摘　　要：添加豆粕(soybean meal,SBM)、发酵豆粕(fermented soybean meal,FSBM)和晶体氨基酸(crystalline amino acid,CAA)替代杂交罗非鱼(Oreoehromis niloticus♀×O.aureus♂)实用饲料中5%的鱼粉,连续投喂初始体重为9.41±0.05g的罗非鱼9周后,通过测定罗非鱼的增重率(WGR,%)、特定生长率(SGR,%)、饲料效率(FE,%)、蛋白质效率(PER,%),并进行肝脏分析和血浆分析,比较各组饲料对罗非鱼生长和非特异性免疫的影响。结果表明,发酵豆粕+晶体氨基酸组的WGR、SGR高于其他3组,鱼粉组的FE高于其他3组;PER方面各组间差异不显著,4组饲料对罗非鱼肝脏组成、血浆成分和存活率没有造成显著差异。Soybean meal （SBM）, fermented soybean meal （FSBM） and crystalline amino acid （CAA） replaced 5% fish meal （FM） in hybrid tilapia （Oreoehromis niloticus ♀ × O. aureus ♂ ） practical diets. After feeding nine weeks （initial weight 9.41 ± 0. 05 g）, weight gain ratio （WGR, % ）, special growth ratio （ SGR, % ）, feeding efficiency （ FE, % ） and protein efficiency ratio （ PER, % ） were determined, and the liver and blood plasma were analysed in order to compare the non-specific immunity and growth condition effected by different diets. The result showed that the FSBM ＋ CAA group was significantly higher than other groups in WGR and SGR. The FM group was significantly higher than other groups in FE. Different diets had no significant effect on PER, liver condition, blood plasma or survival.
