The present study was carried out to determine the blood macromineralprofile of Assam local sheep grazing in similar pasture. For the investigation, plasma sample was taken for assessing the level of Ca, P, Mg, Na, K, and Cl, which were found to be 10.9 ± 0.18 (mg/dl), 7.6 ± 0.27 (mg/dl), 2.6 ±0.04 (mg/dl), 146 ± 1.5 (mmol/l), 4.5 ±0.16 (mmol/l) and 113 ± 1.9 (mmol/l), respectively. The findings may be of use for physiological characterization of the indigenous sheep breed of Assam. It mays also aid in assessing the health as well as supplementation of mineral mixture for proper maintenance of health and optimization of productive performance of the sheep. However, acomprehensive study is warranted on this aspect to evolve the correlations between blood concentrations of these macroelements and productive performance of this breed.
