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.

Abstract

Bu çalışmada süthane ineği yemlerindeki Cd, Co, Cr, Cu, Fe, Ni, Pb ve Zn konsantrasyonları atomik absorpsiyon spektrofotometresi ile ölçülmüştür. Bu amaçla toplam 47 adet fiğ, saman, suni yem ve buğday örneği Trakya bölgesinin bazı köylerinden toplanmıştır. Ortalama Cd, Co, Cr, Cu, Fe, Ni, Pb ve Zn konsantrasyonları sırasıyla 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 kuru ağırlık olarak bulunmuştur. En yüksek Cu, Fe, Zn konsantrasyonları suni yemde bulunurken, en yüksek Cd, Co, Cr, Ni, Pb konsantrasyonları saman örneklerinde bulunmuştur. Ölçülen elementlerin kaynaklarını ayırt etmek için faktör analiz uygulanmıştır. Yemlerdeki Cd, Co, Cr, Ni, Pb miktarları arasında yüksek pozitif korelasyon katsayıları gözlenmiştir. Fiğ, saman ve buğdaydaki ortalama Cd konsantrasyonları süthane gıda organizasyonu tarafından tavsiye edilen limit değerlerden daha yüksek bulunmuştur
