Abstract

A total of 210 milk samples of Jersey cows were used to determine ∞ si-casein, β-casein, k-casein and β-lactoglobulin phenolypes and their gene frequencies. Polyacrylamid-gel tecnique was used to determine milk protein phenolypes. Two alleles were found in each iocus namely B and C at ∞ si-Cn locus, A and B at β-Cn, k-Cn and β-Lg loci. Only the observed distribution of ∞ si-Cn genolypes differed significantly from the expected. The highest average milk yield with 2567.3 kg was found and the lowest with 2467.8 kg in the kCn B phenolype. However, the analyses of variance revealed that there was no significant relationship between milk protein polymorphism and first lactation milk yield.

Özet

Karaköy Tarım İşletmesinde yetiştirilen 210 baş Jersey ineğe ait süt numunelerinde asi–kazein, b-kazein, k-kazein ve b-laktoglobulin fenotipleri belirlenmiş ve gen frekansları hesaplanmıştır. Fenotiplerin açığa çıkarılmasında poliakriliamid-jel elektroforez tekniği uygulanmıştır. asi–Cn lokusunda B ve C allelleri, b-Cn, k-Cn ve b-lg lokuslarında ise A ve B allelleri tesbit edilmiştir. Sadece asi–Cn lokusunda Hardy-Weinberg kuralından sapma belirlenmiştir. İlk laktasyon süt verimi bakımından en yüksek ortalama b-Cn A fenotipinde (2567.3 kg), en düşük ortalama ise k-Cn B fenotipinde (2467.8 kg) görülmüştür. Fenotip grupları arasında ilk laktasyon süt verimi için yapılan varyans analizleri sonucunda gruplar arasında önemli bir farklılık bulunamamıştır.
