In this study concentration of five micro elements Fe, Cu, Zn, Co and Mn in eight species of rangeland forbs Prangus uloptera, Medicago sativa, Lotus goeblia, Trifolium montanum, Sanguisorba minor, Stachys inflate, Melilotus officinalis and Ferula ovina were Measurement. The species sampled at three phenological stages, vegetative, flowering and seeding of random sampling was carried out in Rangeland Taleghan. To measure micro elements atomic absorption devices was used. For comparison of amounts elements with the required level ram of NRC2007 Table were used. The amount of the elements by using the t test with a fixed amount with the level of required ram was compared. The results showed that the amount Zn of most species at all phenological stages is less than the required level of ram, but the amount of Fe, Co, Mn and Co in all species studied at three phenological stage higher than is needed Fashandi race ram, and the amount achieved in all species and phenological stages significant difference in the levels of 99% and 95% with the level of is required in ram. According to the shortage of Zn use of mineral supplements for stay healthy dominant livestock area and reach the optimum level of livestock performance, are necessary.
