摘　　要：以内蒙古苏尼特左旗边境草原区放牧和舍饲苏尼特羊为研究对象,测定并比较二者血液中的矿物质元素含量。结果表明,放牧羊血液中铜(Cu)、锌(Zn)、钙(Ca)、磷(P)、铁(Fe)含量均显著低于舍饲羊(P<0.05),二者血液中镁(Mg)含量差异不显著(P>0.05)。该地区放牧羊缺乏铜(Cu)、锌(Zn)较为严重。The blood mineral elements content of grazed and house feeding Sunit Sheep in border steppe region of Sunitezuo County were determined and comparatively analyzed. The results showed that the content of Cu, Zn, Ca, P and Fe in blood of grazed Sunit Sheep were significantly lower than that of house feeding Sunit Sheep (P<0.05). While the content of Mg in blood of grazed Sunit Sheep were lower than that of house feeding Sunit Sheep, no significances were observed (P>0.05). It was indicated that the grazed Sunit Sheep seriously lacked Cu and Zn.
