为探究万寿菊（Tagetes erecta L）粉对黄金锦鲤（Yamabaki ogon）生长性能及抗氧化能力的影响,试验选用初始体重为（25.39±1.23）g的黄金锦鲤540尾,随机分为6组,分别标记为D1~D6,其中D1组为对照组,D2~D5组为试验组,每组3个重复,分别投喂含0.00%、0.50%、1.00%、2.00%、4.00%、8.00%万寿菊粉的6组等氮等能饲料。饲养60 d后分析不同水平万寿菊粉对黄金锦鲤生长和抗氧化能力的影响。结果表明：在生长方面,D5组增重率和蛋白质效率提升最显著且比对照组分别提高了58.66%、92.77%,D6组肥满度提升最显著且比对照组提高了36.95%,D5组饵料系数降低最显著且比对照组降低了63.69%（P〈0.05）。抗氧化能力方面,D5组的血清、头肾和脾超氧化物歧化酶（SOD）活力提高最显著且分别比对照组提高了71.21%、117.92%、230.76%,D4组肝胰脏和中肾SOD活力提高最显著且分别比对照组提高了110.82%、92.28%（P〈0.05）;D5组肝胰脏、头肾和脾过氧化氢酶（CAT）活性提升最显著且分别高于对照组93.50%、50.38%100.83%,D4组血清和中肾CAT活性提升最显著且分别高于对照组4.11%、66.31%（P〈0.05）;D5组的血清、肝胰脏、头肾、中肾和脾的谷光甘肽（GSH）含量提升最显著且分别比对照组提高了341.38%、223.91%、230.33%、372.26%、439.07%（P〈0.05）;D5组的血清、头肾和脾GSH-PX含量提升最显著且分别比对照组提高了112.07%、155.67%、236.28%,D6组肝胰脏谷光甘肽过氧化物酶（GSH-PX）含量提升最显著且分别比对照组提高了157.47%（P〈0.05）,试验组的中肾GSH-PX含量提高不显著（P〉0.05）;D5组血清、肝胰脏、头肾和脾的丙二醛（MDA）含量降低最显著且分别比对照组降低了36.94%、51.25%、47.79%、81.25%（P〈0.05）,而试验组中肾MDA含量降低不显著（P〉0.05）。研究表明,饲料中添加4.00%万寿菊粉能够有效促进黄金锦鲤生长性能,并提高其抗氧化能力。

英文摘要：

The study was investigated the effects of different levels of marigold powder （0% -D1, 0.5% -D 2, 1%- D3,2%-D4,4%-D5,8%-D6）on growth and antioxidant capacity in Gold brocade carp （Yamaboki ogon）.A total of 540 Gold brocade carp with initial average body weight of（25.39±1.23）g were randomly divided into 6 treatment groups with 3 replicates of 30 each.The indicators of samples were measured at 60 d.The results showed that： In terms of growth,the rate of weight growth rate and protein efficiency ratio of D5 group that were the most significantly increased and 58.66%, 92.77% higher than the control group,the condition factor of D6 group that was the most significantly increased and 36.95% higher than the control group（P 〈 0.05） ;the feed conversion ratio of D5 group that was the most significantly de-creased 63.69% lower than the control group （P 〈 0.05）.In terms of antioxidant capacity,superoxide dismutase（SOD）ac- tivity of serum,head kidney and spleen in D5 group that were the most significantly increased and respectively 71.21%, 117.92%, 230.76% higher than the control group, SOD activity of hepatopancreas and kidney in D4 group that were the most significantly increased and respectively 110.82%, 92.28% higher than the control group （P 〈 0.05） ; Catalase（CAT） activity of hepatopancreas,head kidney and spleen in D5 group that were the most significantly increased and 93.50%, 50.38% 100.83% higher than the control group , CAT activity of the serum and kidney that were the most significantly increased and 4.11%, 66.31% higher than the control group （P 〈 0.05）;Glutathione （GSH） activities of serum, hepatopancreas, head kidney, kidney and spleen in D5 group that were the most significantly increased and 341.38%,223.91%,230.33%,372.26%,439.07% higher than the control group（P 〈 0.05） ;Glutathione peroxidase（GSH- PX）activities of serum,head kidney and spleen in D5 group that were the most significantly increased respectivel
