| Abstract: | Fifteen micro elements, such as Be, Ba, Pb, Ti, Mn, Ga, Cr, Ni, V, Cu, Zr, Co, Sr, Y and Yb were contained in the soil of Jingtai, the typical Tansheep producing area, Gansu Province. In which, 13 of them were found in mixed grasses of related grassland except for Be and Co. The content of Yb in mixed grasses was significantly lower than that in soil. The sort and concentration of micro elements varied remarkably in wool. The wool of adult ewe only contained Pb, Ti, Mn and Cu. However, the wool of one month furlamb contained 13 micro elements. They were Ba, Pb, Ti, Mn, Cr, Ni, Cu, Zr, Ag, Zn, Sr, Mo and Yb. Concentration of micro element in adult ewe was much lower than that of lamb for same micro element. In addition, lambs wool contained Ag, Zn and Mo that were not found in soil. Compared with the Mongolian lamb at same age, one month Tan furlamb had the ability for accumulating many micro elements, especially Ba, Cr, Ni, Zr, Ag, Zn, Sr, Mo, Yb and Cu. This was the essential factor to form the nu |
