Aim: The objective of this study was investigation of OLR1 gen polymorphism among different cattle breeds in Turkey.

Materials and Methods: A total of 147 blood samples were collected from Anatolian Grey (AG), Anatolian Black (AB) and South Anatolian Red (SAR) cattle breeds and DNAs were isolated. PCR-RFLP method was used to determine allele types. Genotype and allele frequencies were calculated after genotyping.

Results: Results are evaluated by square test (χ2). The significance level was taken as 0.05. While AG cattle breed deviated from HW equilibrium, SAR and AB cattle breeds were on the HW equilibrium and they are similar to each other.

Conclusion: It is thought that the effect of polymorphic region in OLR1 gene on milk fat and the ratio of milk fat will be more efficient by studying with various polymorphic areas, and by using other cattle races that they have effects on similar characteristics of milk.
