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.
本研究旨在确定三种土耳其特有牛种（NL、GR 和 SR）血液中某些重金属的季节性变化。在夏季和冬季，从 12-24 月龄的 180 头牛中采集了血液样本。分析了必需（Zn、Cu、Fe、Co 等）和非必需（Cd、Hg、As、Cr、Pb 等）重金属的水平。除 Co 外，所有重金属水平在两个季节中均显著高于其他物种（p < 0.05）。在所有品种中，夏季 Fe 和 Co 水平均显著较高（p < 0.05），冬季 Mn 水平较高（p < 0.05）。分析的所有金属水平均在牛品种可接受的国际范围内。
