| Popis: | The objective of this study was to evaluate the relationship between the polymorphism within GHRH gene (GHRH/HaeIII) and milk production traits for Polish Holstein-Friesian using PCR-RFLP technique for genotyping. The molecular background of this mutation was defined as the A→C transversion at the intron 2. A total of 220 cows were examined. The following frequencies were established: 0.0227 for genotype AA, 0.3227 for AB, and 0.6546 for BB; 0.1841 for the allele GHRHA and 0.8159 for GHRHB. A highly significant association was found between the GHRH/HaeIII polymorphism and milk performance. The BB-genotype cows were characterised by a higher fat yield and percentage (P ≤ 0.01). |
