摘要
在饲料中添加600、900、1800mg/kgMnCl2建立亚慢性锰中毒模型,分别在试验开始后第30、60、90d剖杀鸡取肝组织,采用火焰原子吸收法检测了锰、铁、铜、锌及钙含量。结果显示,与对照组相比,各染锰组鸡肝中锰、铜含量升高;锌呈波动性升高;铁、钙含量降低,呈一定的时间-剂量效应。其中锰与铜呈显著正相关,锰与铁呈显著负相关。表明,过量锰对鸡肝中铁、钙、铜、锌等元素有不同程度的干扰,对肝造成损伤。
Different levels of 600mg/kg,900mg/kg and 1800mg/kg MnCl_ 2 were added into the forage to establish the sub-chronic manganism model.On days 30,60 and 90 post-exposure-to-MnCl_2,the livers of chickens were respectively collected to detect the contents of Mn,Fe,Cu,Zn and Ca by the flame atomic absorption spectrometry.Compared with the control group,the contents of Mn and Cu increased,the content of Zn took on a fluctuated change and the contents of Fe and Ca decreased in each treatment group,which had a time-dose relationship.There were significantly positive correlation between Mn and Cu and significantly negative correlation between Mn and Fe.In conclusion,the excess manganese could change the contents of Mn,Fe,Cu,Zn and Ca in the livers and damage the livers of chickens.
