Farklı ırk sığırların serumlarında bazı eser element ve elektrolit düzeyleri

Bu çalışmada Atatürk Üniversitesi Araştırma ve Uygulama Çiftliğinde soğuk iklim ve yüksek rakımda (2000 m) yetiştirilen 20 adet Holstein (10 adet dişi ve 10 adet erkek) ve 20 adet Brown Swiss(10 adet dişi ve 10 adet erkek) olmak üzere 40 adet hayvan kullanılmıştır. Ortalama yaşları 11-12 aylık olarak seçilen hayvanlar yaz mevsiminde merada beslenmiştir. Kan serumlarında çinko (Zn) ve bakır (Cu) düzeyleri atomic absorption spectrophotometere (AAS) ile, magnezyum (Mg), kalsiyum (Ca), fosfor (Pi), demir (Fe), sodyum (Na) ve potasyum düzeyleri ise ticari kit kullanılarak otoanalizörde analiz edilmiştir. Yapılan istatistiki analizlerde incelenen elementlerin serum düzeylerinin birbirine yakın olduğu ve ırklar arasındaki farkın önemsiz olduğu bulunmuştur.

Serum levels of some trace elelments and electrolytes in different cattle breed

In this study, a total of 40 cattle [20 Holstein cattle (10 males and 10 famales) and 20 Bfown Swiss Cattle (10 males and 10 famales)] were taken. The animals were grown in the pasture of the Agricultural College Farm of Atatürk University at on altitute of 2000 m above sea level and at cold climatic conditions. The animal were grazed in the pasture in the summer. All the animals had an average age of 11-12 months. Serum zinc (Zn) and copper (Cu) levels were analyzed by atomic absorption spectrophtometer and serum magnesium (Mg), calcium (Ca), phosphorus (Pi), iron (Fe), sodium (Na) and potassium (K) levels were measured on an autoanalyzer by using commercial kits. In the statistical evaluation, the serum levels of the elements measured were sililar in two groups and the differences were not statistically significant.There were no significant differences between the males and females. There were also no significant differences among in breeds regarding levels of minerals.
