Investigation of Heavy Metal Levels in Blood Samples of Three Cattle Breeds in Turkey
The aim of this study is to determine seasonal changes in the blood levels of some heavy metals in three Turkey-specific cattle breed: Native Land (NL), Grizzle Race (GR), and South Anatolian Red (SR). 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.
