摘　　要：为研究壳寡糖对南美白对虾（初始体重约1．23g）的生长和血清生化指标影响，设置了含壳寡糖0mg／kg、125mg／kg、250mg／kg、500mg／kg、1000mg／kg的5组试验饲料，经过8周的饲养实验。结果表明，不同含量的壳寡糖对南美白对虾的增重率、特定生长率、饲料系数和成活率均无显著影响（P〉0．05）；对南美白对虾血清中的肌酐、葡萄糖、钙离子、总胆固醇、甘油三脂和低密度脂蛋白胆固醇均无显著影响，但可使高密度脂蛋白胆固醇显著增加，促进脂类代谢；综合试验结果得出饲料中壳寡糖添加250—500mg／kg为宜。8- week feeding trial was conducted to investigate effects of oligochitosan levels （0 mg/kg, 125 mg/kg, 250 mg/kg, 1000 mg/kg） on growth and serum biochemical indices in Litopenaeus vannamei （ primary body weight was about 1.23g）. The results showed that： there was no significant difference in weight gain rate, specific growth rate, feed coefficient, survival rate （ P 〉 0. 05 ） in different oligochitosan levels ; and there was also no remarkable difference in glucose, creatinine, calcium ion, total cholesterol, low density lipoprotein -cholesterol in the serum of L. vannamei in different oligochitosan levels（ P 〉0. 05 ） ; but significant difference occurred to high density lipoprotein-cholesterol, fat metabolize accelerated. In conclusion, 250 - 500 mg/kg oligochitosan in diet was appropriate.
