Abstract The aim of this study was to assess the concentration of Se and other minerals in sheep and the supplied feed. Four macrominerals (Ca, P, Mg, and S), 7 microminerals (Se, Fe, Zn, Cu, Mn, Co, and Mo), and 2 toxic minerals (Cd and Pb) were analyzed in 69 feed and 292 sheep blood samples from 30 farms in different regions of Kosovo. The samples were analyzed using inductively coupled plasma mass spectrometry, and mineral concentrations in whole blood were measured to assess their status in animals. Concentrations of the different minerals in feed were found in the following ranges: 1.9 to 9.5 g Ca/kg DM, 0.8 to 3.2 g P/kg DM, 0.8 to 3.2 g Mg/kg DM, 1.0 to 2.8 g S/kg DM, 6 to 82 µg Se/kg DM, 33 to 970 mg Fe/kg DM, 15 to 42 mg Zn/ kg DM, 2.6 to 7.5 mg Cu/kg DM, 26 to 250 mg Mn/kg DM, 0.04 to 0.88 mg Co/kg DM, 0.05 to 0.86 mg Mo/ kg DM, 0.07 to 2.02 mg Pb/kg DM, and 0.02 to 0.19 mg Cd/kg DM. Concentrations of the microminerals analyzed in whole blood were found in the following ranges: 15 to 360 µg Se/L, 190 to 500 mg Fe/L, 1.4 to 3.8 mg Zn/L, 0.3 to 2.6 mg Cu/L, 6 to 243 µg Mn/L, 0.1 to 19.6 µg Co/L, and 1.8 to 66.0 µg Pb/L. Among all minerals, the largest deficiency was found for Se both in feed and sheep blood, with 82% of feed samples and 83% blood samples being inadequate, and its supplementation is necessary. Selenium-supplemented sheep had significantly higher Se concentration in blood than non-supplemented sheep (P < 0.01). In addition, other macro- and microminerals in feed such as P, S, Cu, and Co were at inadequate concentrations at some of the farms, and supplementation may also be needed for these minerals.

Abstract Objective: An investigation of the potential influences of As, Hg, Tl and Pb on Se metabolism, which can suggest new drugs to cope the poisonousness of Se. Methods: Chronic cases were carried out with the nursing of rats with a purified diet of water-soluble vitamin mix, fat-soluble vitamin mix, saccharides, oil, and salts. One week after the basic diet, the rats taken Se have received diets containing 10 ppm of the element as sodium selenite or selenate added in the salts. Result: As, Hg, and Tl were repressed the volatized Se excreted from the lungs. As has assisted the biliary excretion of Se and inhibited the chronic selenosis. Tl has increased the retention of Se in the liver and kidney, but, had no chronic effect on the amount of Se deposited in all the studied tissues. Similarly, Hg has increased the retention of Se but in the spleen and carcass of rats indicating to the high Se concentration in blood. Hg and Tl have inhibited the Se in urine. Conclusion: No effects of the doses rich in As, Hg, and Tl on the Se excretion in fecal. Even though, we suggest As as a possible medication to chronic selenosis.
