Geçiş Dönemindeki İneklerde Serum Bakır, Çinko, Manganez ve Kobalt Düzeyleri

Bu çalışmada, geçiş döneminde Montafon ineklerinde (n= 10) geçiş döneminde serum bakır (Cu), çinko (Zn), manganez (Mn) ve kobalt (Co) düzeylerinin saptanması amaçlandı. İneklerin V. jugularis'lerinden doğumdan 3 hafta önce, doğum anı ve doğumdan 3 hafta sonra kan örnekleri alındı. Kan serumunda Cu, Zn, Mn ve Co düzeyleri atomik absorbsiyon spektrofotometreyle ölçüldü. Çalışma sonucunda, geçiş dönemindeki ineklerde serum Cu, Zn ve Mn düzeyleri doğum öncesine göre, doğum anı ve sonrasında, serum Co düzeyleri ise doğum sonrasında azaldığı belirlendi. Bu nedenle doğum sonrası azalan mikroelementler açısından ineklerin desteklenmesinin yararlı olduğu kanısına varıldı. Bu çalışmanın amacı, geçiş dönemindeki Montafon ineklerde Cu, Zn, Mn ve Co düzeylerinin araştırmak ve ihtiyaç düzeylerini belirleyerek, eksikliklerin giderilmesi için gerekli önerileri yapabilmektir.

Serum Copper, Zinc, Manganese and Cobalt Levels of Cows During the Transition Period

In this study, it was aimed to determine serum levels of copper (Cu), zinc (Zn), manganese (Mn) and cobalt (Co) in Mondofon cows (n=10) during the transition period. Blood samples were taken by venipuncture of the jugular vein on three weeks before parturition, parturition time and three after parturition, respectively. Blood serum samples were analysed for Cu, Zn, Mn and Co levels using Atomic absorption spectrometry. As a result, it was determined that Cu, Zn and Mn levels in transition cows decreased at the moment of parturition, after parturition, and serum levels of Co decreased after parturition. So, it was concluded that supporting cows with micro elements in postpartum is beneficial.
