Blood samples were collected in summer and winter seasons from a total of 180 cattle aged 12-24 months. The levels of the essential (Zn, Cu, Fe, Co etc.) and non-essential (Cd, Hg, As, Cr, Pb, etc.) heavy metals were analyzed. All heavy metal levels, except that of Co, were significantly higher (p < 0.05) in SR in both seasons compared to the other species. In all breeds, Fe and Co levels were statistically higher (p < 0.05) in the summer season while Mn level was higher (p < 0.05) in the winter season. The levels of all metals analyzed are within the internationally acceptable limits for cattle breeds.eninfo:eu-repo/semantics/closedAccessHeavy metalsICP-OESSerumCattleBloodArticle103573974410.1007/s00128-019-02712-z2-s2.0-8507361363631520140Q2WOS:000491548300015Q3
