| 摘 要： | 在云南省会泽县和昭通市进行了 6个不同阶段的肉牛微量元素补饲试验 ,添加补充料后 ,肉牛日粮、血浆和血清中微量元素Zn、Mn和日粮I、血浆蛋白结合碘 (PBI)含量均有不同程度的增加 ,部分理化指标有显著变化 (P <0 0 5 ) ,表明在农村传统饲养模式下 ,肉牛微量元素Zn、Mn营养充足 ,但至少缺乏微量元素I,添加易吸收Zn、Mn对肉牛生产性能有一定的促进作用

| Abstract: | We designed six experiments to explore the status of beef cattle on trace element Zn Mn and I in mortheast of Yunnan The results show that:the trail of concentration of beef cattle on trace element Zn Mn and I in serum plasma and diet are higher than of the control At same time, we find that the concentration of trace element I ration in northeast of Yunnan is lower than recommended sufficient value(RSV) We draw a conclusion that beef cattle is lack of trace element I at least,but Zn and Mn is sufficent |
