在中华倒刺鲃每千克基础饲料中分别添加免疫多糖2g、免疫多糖4g、维生素C（VC）700mg、VC1400nag、VC700mg＋免疫多糖2g、VC700mg＋免疫多糖4g、VC1400mg＋免疫多糖2g、VC1400mg＋免疫多糖4g，以基础饲料为对照组，连续投喂2周后，通过测定血液白细胞的数量，白细胞吞噬能力，血清、头肾和脾脏的溶菌酶活力，探讨不同浓度的免疫多糖和VC对中华倒刺鲃非特异性免疫功能的影响．结果表明：VC和免疫多糖都能提高中华倒刺鲃免疫机能，且免疫多糖和VC二者间在较低浓度组合时有协同作用，高浓度组合时反而产生拮抗作用．免疫多糖和VC的最适宜组合浓度为（VC700mg＋免疫多糖2g）／kg基础饲料．

Effects of immunopolysaccharide and Vitamin C on the non-specific immune response of Spinibarbus sinensis Bleeker were investigated after supplemented with immunopolysaccharide 0, 2,4 g/kg · diet,Vitamin C 0,700,1 400 mg/kg · diet, （Vitamin C 700 mg＋ immunopolysaccharide 2 g）/ kg·diet, （Vitamin C 700 mg ＋ immunopolysaccharide 4 g）/kg · diet, （Vitamin C 1 400 mg ＋ immunopolysaccharide 2 g）/kg · diet, （Vitamin C 1 400 mg ＋ immunopolysaccharide 4 g）/kg · diet. After 2 weeks,the number and the phagocytic activity of the leucocytes, the lysozyme activity of the serum, the head kidney and the spleen were determined. The results show a significant effect of immunopolysaccharide and vitamin C on the non-specific immune response of Spinibarbus sinensis. The trial reveals a synergistic action among the factors, immunopolysaccharide and Vitamin C at lower concentration,and a antagonistic action among the factors at higher concentration. In this research, the optimal combination of immunopolysaccharide and vitamin C supplementation in Spinibarbus sinensis Bleeker is （vitamin C 700 mg ＋ immunopolysaccharide 2 g）/kg · diet.
