中文摘要:
      为探究饲料中黄藤素含量对吉富罗非鱼生长、抗氧化能力和非特异性免疫的影响。在基础饲料中添加0(A组)、0.01%(B组)、0.02%(C组)、0.04%(D组)和0.08%(E组)的黄藤素,饲喂平均体质量为0.5g的吉富罗非鱼幼鱼12周。结果表明:(1)饲料中黄藤素的含量对罗非鱼摄食率、末重、日增重系数、饲料系数无显著影响(P>0.05),E组体增重显著高于对照组(P < 0.05)。(2)随着黄藤素添加量的提高,血清中AKP、T-AOC活性呈上升趋势,其中以E组最高,D组SOD活性显著高于其它各组(P < 0.05),各试验组MDA活性均低于对照组。(3)随着黄藤素添加量的提高,肝脏中SOD、AKP、T-AOC、CAT活性随黄藤素添加量的提高呈上升趋势,E组GSH-Px活性显著高于其他各组(P < 0.05),各处理组MDA活性均低于对照组。(4)C组和D组LZM活性显著高于对照组(P < 0.05),D组巨噬细胞吞噬活性及基因IL-1β表达量显著高于对照组(P < 0.05),C组基因TNF-α表达量显著高于对照组(P < 0.05),血清补体C4活性呈上升趋势,以E组最高。结果表明:饲料中添加0.04%~0.08%黄藤素在维持良好生长性能的同时能有效提高罗非鱼抗氧化能力。
英文摘要:
      To investigate the effects of the content of palmatine in the feed on the growth, antioxidant capacity and non-specific immunity of gifforia, added 0, 0.01%, 0.02%, 0.04% and 0.08% of palmatine in the basic feed, respectively, and fed juvenile gifforia with an average body mass of 0.5g for 12 weeks. The results showed that :(1) the dietary palmatine content had no significant effect on the feeding rate, final weight, daily weight gain coefficient and feed coefficient of tilapia (P >0.05), and the body weight gain in the E treatment was significantly higher than that in the control group (P < 0.05). (2) with the increase of the palmatine , the activity of AKP and T-AOC in serum showed an increasing trend, with the highest in the E treatment, the SOD activity of the D treatment was significantly higher than that of the other treatments (P < 0.05), and the MDA activity of each experimental treatments were lower than that of the control group. (3) with the increase of the palmatine ,The activities of SOD, AKP, T-AOC and CAT in the liver showed an increasing trend with the increase of the amount of flavine. The GSH-Px activity in the E treatment was significantly higher than that in other treatments (P < 0.05), and the MDA activity in each treatments were lower than that in the control group. (4) The LZM activity of the C and D treatments was significantly higher than that of the control group (P < 0.05),the phagocytic activity and expression level of gene IL-1β in the D treatment were significantly higher than that in the control group (P < 0.05), the expression level of gene TNF-α in the C treatment was significantly higher than that in the control group (P < 0.05), and the serum complement C4 activity showed an increasing trend, with the highest level in the E treatment. The results showed that adding 0.04%~0.08% palmatine in feed could effectively improve the antioxidant capacity of tilapia while maintaining good growth performance.
