Abstract

This study was conducted to determine the status of some micro minerals notably iron, copper, zinc, cobalt and nickel, in forbs and grasses in plants at the flowering and seed set stages for sheep grazing on natural range land, at Sheikan Locality, North Kordofan State, Sudan in the year 2011 and 2012. Changes in mineral concentrations with maturity often reflect increases in the proportion of stem to leaf with stems showing lower mineral concentrations than young leaves. Samples of plants' shoots (leaves and stems) were picked randomly by hand according to diet selected by sheep and ICP was used to determine minerals. A higher concentration of micro minerals was found in forbs compared with grasses (P < 0.05). It was concluded that the rangelands of North Kordofan State, containing a mixture of grasses and forbs, are good sources of micro minerals at seed set stage of growth that can meet the requirements of sheep. Plants must obtain a number of inorganic mineral elements from their environment for a successful growth and development of both vegetative and reproductive tissues. These minerals serve several functions such as structural components in macromolecules, cofactors in enzymatic reactions and osmotic solutes needed to maintain proper water potential to provide charge balance in cellular compartments. Trace elements are essential parts of many physiological processes such as energy production, enzyme activity, hormone production , collagen formation, vitamin and tissue synthesis, oxygen transport and other physiological processes related to health, growth and reproduction. Their deficiency causes a variety of pathological consequences such as cardiac conditions in addition to immunological and hormonal functions and metabolic defects (Suttle, 2010). Reports on clinical Zn deficiency in cattle under field conditions in Sudan are relatively rare. The concentration of Cu was found to be low in sera and tissues of various Sudanese animals raised under nomadic system. The effect of dietary supplementation during different physiological states on serum concentrations of Cu and Zn were investigated.
