为探讨营养小肽对黄金鲫生长、血清生化和抗氧化性能的影响。试验分为1个对照组和2个试验组,分别投喂基础饲料和添加2.0%营养小肽的饲料。结果显示:养殖52d和128d,体质量、体长、增重率和特定生长率试验组均大于对照组。养殖128d时,试验组与对照组有显著差异(0.01≤P 0.05)。试验组氧化氢酶(Ca.)活力降低了8.77%和3.43%,对照组降低了11.86%(P> 0.05)。试验组谷胱甘肽过氧化物酶(GSH-PX)活力提高了33.94%和30.75%,对照组提高了25.33%(P> 0.05)。试验组总抗氧化能力(T-a.C)能力提高了12.50%和4.35%,对照组降低45.71%(P> 0.05)。试验组丙二醛(MDa.含量提高了45.19%和56.65%,对照组提高80.85%(P> 0.05)。试验组一氧化氮(NO)含量提高了126.38%和38.91%,对照组降低了11.25%(P <0.01)。营养小肽对养殖黄金鲫的生长有一定的促进作用,脂质代谢处于健康水平,具有一定的抗氧化性,可有效提高黄金鲫内源性抗氧化酶活力和抗氧化能力,同时增强机体维持自由基平衡的能力。
