摘要
二氢吡啶以 4个不同水平 (0、50、1 0 0、1 50mg kg)添加饲喂尼罗罗非鱼 64d ,探讨了二氢吡啶的适宜添加水平及其对机体抗氧化性能的影响。结果表明 ,添加二氢吡啶 (50、1 0 0、1 50mg kg)可使日增重分别提高 1 7.2 %(p <0 .0 5)、9.1 %、2 .5 % ,体重特定生长率提高 1 5 .5 %、9.3 %、5 .1 % ,饵料系数分别较对照组降低 1 2 .1 %、1 2 .7%、5 .9% ,但对试验鱼平均存活率无影响 ;二氢吡啶可显著降低试验组肝LPO含量 ,提高机体的抗氧化性能 ;试验组肝SOD活性呈上升趋势 ,未达显著水平 ;二氢吡啶可分别降低试验组肝脂肪 (绝干 )的含量 1 9.7% (p<0 .0 5)、1 8.6 % (p <0 .0 5)、2 4 .1 % (p <0 .0 1 ) ,对血清GOT和GPT的活性无影响。在试验剂量范围内 ,机体抗氧化性能随剂量的增加而增强 ,但生长速度并非如此 。
Tilapia nilotia were divided ran domly into 4 groups. The groups were f ed with diets containing 0(control group), 50,100 or 150 mg/kg Diludin under t he same circumstance for a period of 64 days. The results indicated that Diludin supplementation (50,100,150 mg/kg) increased the average daily weight gain by 1 7.2% (p<0.05), 9.1%, 2.5% respectively, specific rates in weig ht increased 15.5%, 9.3%, 5.1% compared with the control group. Feed to gain rat io (g/g) decreased 12.1%, 12.7%, 5.9% respectively. The average survival rate was not influenced. Lipid oxidation (LPO) levels of liver were lower significantly compared with the control group, which showed that Diludin could improve the antioxidant activity of the body. Diludin supplementation had the tendency of improving the superoxi de di smutase (SOD) activity of liver. Liver lipid contents were lower by 19.7%(p<0.05), 18.6%(p<0.05), 24.1%(p< 0.01) respectively compared with the control group. The activity of GOT and GPT of serum were not influenced by Diludin supplementatio n. In this experiment the antioxidant activity of body was better as Diludin add ed to the diets, but the growth performance was not. The fish that grow the m ost fast may not be the one whose antioxidant activity was the best.
