采用全因子试验设计,配制含有3个蛋白质水平(32%﹑30%﹑28%)和3个糊精水平(15%﹑20%﹑25%)共9组试验饲料,每组3个平行,养殖周期为8周,探讨了对乌克兰鳞鲤(Cyprinus carpio)生长﹑体成分及抗氧化能力的影响.结果表明,蛋白质和糊精对生长性能无交互作用(P>0.05).随着蛋白质水平升高,肝体比显著提高(P<0.05);随着糊精水平增加,相对增重率﹑特定增长率出现明显升高.蛋白质和糊精水平对体内脂肪及灰分含量存在明显的交互作用(P<0.05). 20%糊精组肝胰脏超氧化物歧化酶(SOD)﹑过氧化氢酶(CAT)活性显著高于15%和25%糊精水平(P<0.05),并且丙二醛(MDA)含量显著低于25%糊精水平(P<0.05).综合分析得出,蛋白水平在30%~32%,糊精水平在20%~25%之间最适宜乌克兰鳞鲤的生长.

3 ×3 factorial experiment was conducted to determine the effects of dietary protein and dextrin levels on growth performance, body composition and antioxidant capacity of Ukraine scale carp.9 experimental diets with 3 protein levels of 32%, 30%, 28% and 3 dextrin levels of 15%, 20%, 25% were fed to triplicate groups of fish for 8 weeks.The results in-dicate that there is no interaction for the growth between protein and dextrin levels(P>0.05).The protein level plays a signifi-cant role on the hepatosomatic index (P<0.05).With the rising of dextrin levels, the weight gain (WG) and special growth ratio (SGR) increase significantly.Significant interactions (P<0.05) between dietary protein and dextrin levels are detected for body lipid and ash.The SOD and CAT activities in hepatopancreas of the group fed with 20% dextrin level are the highest, and the MDA contents of this group is lower than that of the 25% group (P<0.05).In conclusion, fish fed diets with protein levels of 30% to 32% and dextrin levels of 20% to 25% get the best growth performance.
