摘　　要：以异育银鲫幼鱼为试验对象,研究不同水平半乳甘露寡糖对其生长性能和非特异性免疫的影响。在基础饲料中分别添加0(对照组)、0.1%、0.2%和0.3%的半乳甘露寡糖,每组设3个重复,每个重复40尾鱼,试验鱼体初始体重为1.03 g左右,每天饱食投喂两次,饲养10周。结果表明,基础饲料中添加0.2%半乳甘露寡糖能显著提高异育银鲫幼鱼的增重率和特定生长率(P<0.05),降低饵料系数(P<0.05),同时能够显著提高鱼体的非特异性免疫功能(P<0.05)。A growth trial was undertaken to investigate the effects of the dietary galactomannan oiigosaccharides levels on growth performance and non-specific immune responses of juvenile gibel carp. Diets were formulated to contain four dietary galactomannan oligosaccharides levels （0, 0. 1%, 0.2% and 0. 3% of dry diet, respectively）. Triplicate groups of 40 fish（ average weight 1.03 g） were stocked and fed to apparent satiation twice daily for 10 weeks. The results showed that the weight gain and specific growth rate of fish were significantly increased by feeding diet added with of 0.2% galactomannan oligosaccharides level（ P 〈0.05 ）, and feed coefficient was significantly decreased. The inclusion of galactomannan oligosaccharides in diets also significantly enhanced non-specific immune responses of juvenile gibel carp（ P 〈 0.05 ）.
