Effect of Growth Hormone Genetic Polymorphism on Calf Birth Weight
Keywords:Bovine growth hormone, Polymorphism, Birth weight, Calf, PCR-RFLP
AbstractThe aim of study were to present relationships between birth weight of 94 Holstein calves with genotype structures of each sample‘s Growth Hormone (GH) determined through PCR-RFLP method and to detect the population‘s genetic variation by determining the genotype and allel frequency distribution. In the study, according to the analysis result, it was determined that Growth Hormone gene LL genotype was 41.9 kg, LL was 40.8 kg, and VV was 42.2 kg for the birth weight. A significant relationship between birth weight with GH genotypes could not be found. It was seen that the calf population is not stable according to Hardy-Weinberg genetic balance test.
