摘　　要：通过测定不同日龄和不同性别异地饲养的第2代闽西南黑兔血清中补体和免疫球蛋白的含量,评价异地饲养闽西南黑兔的非特异性免疫性能,以期为闽西南黑兔的抗病性研究提供参考。结果表明,不同日龄闽西南黑兔血清中补体(C_(3)、C_(4))和免疫球蛋白(IgM、IgG)的含量存在显著差异(P<0.05),150日龄闽西南黑兔血清中C_(3)含量显著高于70日龄闽西南黑兔(P<0.05),150日龄闽西南黑兔血清中C_(4)、IgM和IgG的含量显著低于70日龄闽西南黑兔(P<0.05);幼龄(70日龄)闽西南黑兔和伊高乐商品兔血清中补体和免疫球蛋白的含量存在性别差异,不同性别成年(150日龄)闽西南黑兔血清中补体和免疫球蛋白的含量无显著差异(P>0.05);不同品种(系)兔血清中补体和免疫球蛋白的含量存在一定差异,闽西南黑兔血清中C_(4)和IgG的含量显著高于伊高乐商品兔(P<0.05),这将为今后的家兔育种工作提供有力素材。By measuring the content of complement and immunoglobulin in the serum of the second generation of Minxinan black rabbits fed in different areas with different ages and different genders,the non-specific immunity of Minxinan black rabbits fed in different areas were evaluated,so as to provide references for the disease resistance characteristics study of Minxinan black rabbits.The results showed that there were significant differences in the content of complement 3(C_(3)),complement 4(C_(4))and immunoglobulin M(IgM),immunoglobulin G(IgG)in the serum of Minxinan black rabbit at different day ages(P<0.05).The content of C_(3)in the serum of 150-day-old Minxinan black rabbits was significantly higher than that of 70-day-old Minxinan black rabbits(P<0.05),and the content of C_(4),IgM and IgG in the serum of 150-day-old Minxinan black rabbit was significantly lower than that of 70-day-old Minxinan black rabbits(P<0.05).There were sex differences in serum complement and immunoglobulin contents in young rabbits(70 day-age)of Minxinan black rabbits and Hycole commercial rabbits(P<0.05),but there was no significant difference in adult rabbits of Minxinan black rabbits(150-day-age)between male and female rabbits(P>0.05).The content of complement and immunoglobulin in the serum had difference among different breeds(lines)of rabbits,the contents of C_(4)and IgG in the serum of Minxinan black rabbit were significantly higher than those of Hycole commercial rabbit(P<0.05),which would provide powerful materials for rabbit breeding in the future.
