摘要: 为探究饲料中添加牡丹籽壳对黄颡鱼(Pelteobagrus fulvidraco)抗氧化能力和非特异性免疫的影响,以饲喂商品饲料的黄颡鱼为空白对照组,以饲喂含有1%和5%牡丹籽油的再制商品饲料的黄颡鱼为阳性对照组,以饲喂含有1%和5%牡丹籽壳的再制商品饲料的黄颡鱼为试验组,养殖时间21 d。测定黄颡鱼血清和肝脏抗氧化酶活性、血清溶菌酶活性及补体C3含量,并在光学显微镜下观察黄颡鱼肝脏组织形态学结构。结果表明,与对照组相比,饲料添加1%牡丹籽壳显著提高黄颡鱼血清中超氧化物歧化酶活性(P<0.001)和补体C3(P<0.05)含量,黄颡鱼肝脏中超氧化物歧化酶和过氧化氢酶活性显著升高(P<0.001),指示肝脏氧化损伤程度的丙二醛含量显著降低(P<0.001),黄颡鱼肝脏形态结构完好,与对照组无明显差异。牡丹籽壳提高黄颡鱼抗氧化能力和非特异性免疫的效果在5%剂量添加组更加显著,与空白对照组相比,血清超氧化物歧化酶、肝脏超氧化物歧化酶和过氧化氢酶活性分别提高了100%(P<0.001)、245%(P<0.001)和176%(P<0.001),血清溶菌酶活性和补体C3含量分别提高了36%(P<0.001)和33%(P<0.01)。与牡丹籽油相比,饲料添加牡丹籽壳能达到与其相同的保健效果。饲料添加牡丹籽壳能有效提高黄颡鱼抗氧化能力和非特异性免疫,适宜添加量为1%~5%。

Abstract: To investigate the effects of dietary peony seed shell on fish oxidation resistance and nonspecific immunity, yellow catfish were fed with 1% or 5% peony seed shell (commercial feed containing 1% or 5% peony seed shell) for 3 weeks. Meanwhile, fish fed with commercial feed only were used as the blank control group, and fish fed with 1% or 5% peony seed oil were used as positive control group. The results showed that, compared with blank control group, the activity of superoxide dismutase (P<0.001) and the content of complement C3 (P<0.05) in serum of fish fed with 1% peony seed shell increased significantly. Liver superoxide dismutase and catalase activities were higher than those of the blank control group (P<0.001), and liver malondialdehyde content decreased significantly (P<0.001). Liver histomorphology of yellow catfish was normal and intact in both the blank control group and 1% peony seed shell group, and there was no obvious difference between the two groups. Peony seed shell had a dose-dependent positive effect on promoting the antioxidant capacity and nonspecific immunity in yellow catfish, all the test indexes in the 5% peony seed shell group showed a remarkably better change. Compared with blank control group, serum superoxide dismutase, liver superoxide dismutase and catalase activities in 5% peony seed shell group increased by 100% (P<0.001), 245% (P<0.001) and 176% (P<0.001), respectively. Serum lysozyme activity and complement C3 content increased by 36% (P<0.001) and 33% (P<0.01), respectively. In both dose groups, peony seed shell showed similar positive effects on yellow catfish compared to peony seed oil, the suitable addition amount was 1%~5%.
