Abstract
In the current work, Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn concentrations were measured in the feed samples of the dairy cattle by means of atomic absorption spectrophotometer. For this purpose a total of 47 common vetch, hay, concentrate feed and wheat samples were collected from the villages of Thrace region. The average concentrations of Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn were found as 1.15 ± 0.19, 3.22 ± 0.64, 4.51 ± 1.60, 3.46 ± 0.94, 90.6 ± 13.5, 7.1 ± 0.4, 9.2 ± 3.9, 42.2 ± 9.2 mg kg -1 , respectively, in dry matter. The highest concentrations of Cu, Fe, Zn were found in the concentrate feed samples while the highest concentrations of Cd, Co, Cr, Ni, Pb have been found in the hay samples. Factor analysis was performed in order to distinguish sources of measured elements. High positive correlation coefficients were observed among Cd, Co, Cr, Ni, Pb amounts of the feed. Average Cd concentrations of common vetch, hay and wheat samples were found higher than limit value recommended by dairy food organization .
本文采用原子吸收分光光度计测定了奶牛饲料样品中Cd、Co、Cr、Cu、Fe、Ni、Pb和Zn的浓度。为此目的，从色雷斯地区的村庄共收集了47个普通紫薇、干草、浓缩饲料和小麦样品。干物质中Cd、Co、Cr、Cu、Fe、Ni、Pb、Zn的平均浓度分别为(1.15±0.19)、(3.22±0.64)、(4.51±1.60)、(3.46±0.94)、(90.6±13.5)、(7.1±0.4)、(9.2±3.9)、(42.2±9.2)mg kg -1。精料样品中Cu、Fe、Zn含量最高，干草样品中Cd、Co、Cr、Ni、Pb含量最高。为了区分所测元素的来源，进行了因子分析。饲料中Cd、Co、Cr、Ni、Pb含量呈高度正相关。普通野豌豆、干草和小麦样品的平均镉浓度高于乳制品组织推荐的限量值。
