Investigation of the Relationship between GHRH and PRL Genes Polymorphsims and Milk Yield in Holstein Cattle Breed Reared in Turkey
Abstract
The aim of this study was to investigate the
relationship between growth hormone, releasing hormone (GHRH) and prolactin hormone (PRL)
genes polymorphisms and 305-day milk yield in Hostein dairy cattle reared in
Turkey. Overall, 150 Hostein dairy cows was used for the study. In order to
determine GHRH genotypes, obtained
PCR products were restricted via HaeIII
enzyme and to determine PRL genotypes,
obtained PCR products were restricted via RsaI
enzyme. The mean differences of 305-day milk yield among the genotype groups of
GHRH and PRL genes were assessed by analysis of variance (ANOVA). Two alleles
(A and B) and three genotypes (AA, AB and BB) for GHRH-HaeIII polymorphism were
observed in examined Hostein cows. The frequency of the A and B alleles was
found to be 0.32 and 0.68, respectively in examined Hostein cows. Two alleles
(A and B) and three genotypes (AA, AB and BB) for PRL-RsaI polymorphism were
observed. The frequency of the A and B alleles was found to be 0.86 and 0.14,
respectively. Finally, GHRH-HaeIII and PRL-RsaI genotype effects on daily and
lactation milk yield was not found to be significant in examined animals.
