摘　　要：本试验旨在研究低聚木糖（ｘｙｌｏｏｌｉｇｏｓａｃｃｈａｒｉｄｅ）对奥尼罗非鱼（Ｏｒｅｏｃｈｒｏｍｉｓｎｉｌｏｔｉｃｕｓ×This experiment was conducted to investigate the effects of dietary xylooligosaccharides（XOS） on growth performance and serum biochemical indices of tilapia（Oreochromis niloticus×O.aureus）.A total of 960 fish with an average body weight of（5.09±0.12） g were randomly divided into 6 groups with 4 replicates in each group and 40 fish per replicate.The fish in control group（G0 group） were fed a basal diet,and those in other 5 groups（G200,G400,G600,G800 and G1000 groups） were fed the basal diet supplemented with 200,400,600,800 and 1 000 mg/kg XOS,respectively.After 8 weeks feeding,weight gain rate（WGR）,feed intake（FI）,feed conversion ratio（FCR）,protein efficiency ratio（PER） and survival rate（SR） were measured.The activities of superoxide dismutase（SOD）,alkaline phosphatase（AKP） and catalyse（CAT）,and total protein（TP） content in serum were determined every 2 weeks,respectively.The results showed that there was no significant difference in the WGR of fish among all groups（P0.05）,however,fish fed diets supplemented with 400 to 1 000 mg/kg XOS had higher WGR than those fed the basal diet.FI and SR of fish in all groups were not significantly affected by the dietary XOS（P0.05）.PER in the G800 group was significantly higher than that in the G200 group（P0.05）,and FCR in the G800 group was significantly lower than that in the G200 group（P0.05）.There was no significant difference in the body conventional components of tilapia（P0.05）.At the 4th week,serum AKP,CAT activities and TP content in the groups with the diets containing XOS were higher than those in the control group,and a significant difference was found between the G400 group and control group（P0.05）.At the 6th week,serum SOD,AKP,CAT activities and TP content in the G400 group were significantly higher than those in the control group（P0.05）.At the 8th week,serum SOD activity in the groups with the diets containing XOS was significantly higher than that in the control group（P0.05�
