Abstract

The purpose of this work was to examine the allele structures of beta- lactoglobulin gene with restriction fragmentlength polymorphism (RFLP) method in Simmental, Brown Swiss, South Anatolian Red and Turkish Grey cattle breeds beingraised in Turkey. The material of the study consisted of 75 heads of Simmental, 75 heads of Brown Swiss, 40 heads SouthAnatolian Red and 40 heads Turkish Grey cattle. DNA materials were isolated from blood samples using phenol- chloroformextraction method. In order to determine the beta- lactoglobulin alleles in polymerase chain reaction (PCR) products, thePCR products were digested with HaeIII endonuclease enzyme. The digest products obtained were determined byelectrophoresis using 4% agarose gel. The AA genotypic frequency was found the highest in Simmental breed; the BBgenotypic frequency was found the highest in the South Anatolian Red (SAR) breed and the AB genotypic frequency wasfound the highest in Brown Swiss breed in beta- lactoglobulin gene. In this study, the B allele frequency was found higherthan the A allele in SAR cattle breeds. But, the A allele frequency was found higher than the B allele in the Simmental breed.At the end of this study, a deviation in Hardy- Weinberg equilibrium (HWE) was observed in terms of beta- lactoglobulinlocus in the breeds examined.
