饲料中Fe、Cu、Mn、Zn对异育银鲫器官、组织相应元素的影响及其相关性研究

以异育银鲫为试验对象,在实用饲料中按照L9(34)正交设计方案补充Fe、Cu、Mn、Zn,经过60 d养殖后,分析鱼体器官、组织与饲料中Fe、Cu、Mn、Zn 4种微量元素的含量、相互比例的相关性。试验结果表明,Fe、Cu、Mn、Zn在鱼体各器官、组织中具有明显的分布特征:鳍中的Fe、Mn、Zn,头骨中的Cu、Mn、Zn,心脏、肝胰脏、脊椎骨中的Fe、Cu,全鱼Cu、Zn,脾中Cu、Mn,肾脏中Mn、Zn,肌肉、卵、肠中Cu,鳃骨中的Zn,鳞中的Mn受饲料中相应元素供给量的影响很大;鱼体器官、组织中Fe、Cu、Mn、Zn比例模式有3种基本类型,脾、肌肉、脑、心脏、肾脏和全鱼属于Fe比例高的类型(称为高Fe型),与饲料中的Fe、Cu、Mn、Zn比例模式非常相近,具有显著的相关性;脊椎骨、鳃骨、肠、头骨和鳍中Fe、Zn两者比例比较接近,属于Fe、Zn比较高的类型(称为高Fe、高Zn型),而鳞和卵属于Zn比例高的类型(高Zn型),这两类类型的Fe、Cu、Mn、Zn比例与饲料中比例模式相关性差。

The contains and comparison relativity of Fe,Cu,Mn and Zn in diet with that in the organs and tissues of carassius auratus gibelio

The Carassius auratus gibelio was the research object.Fe,Cu,Mn,Zn complement measures in diet were designed according to the L9(34)hand over design.The fish were farmed for 60 days in the room circulation farming system.Fe,Cu,Mn,Zn contain of the diet and organs and tissues were measured by the atom absorbs light photometer method.The results show that,the obvious difference of contain distributes of Fe,Cu,Mn,Zn in carassius auratus gibelio organs and tissues were discovered.The Fe,Cu,Mn and Zn in diet had ...
