Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2017, Vol 42, Issue 334
Abstract
The study analyzed the polymorphism of single nucleotide substitution C9681T (A536V) type, located in exon 10 of prolactin receptor gene. The study was conducted in a herd of cattle of Polish Holstein-Friesian breed of black and white variety. Identification of genotypes of individuals was performed using PCR-RFLP. The study stated the following frequency of C9681T polymorphism alleles: C-0.81 and T- 0.19. TT genotype was not identified in the analysis. Statistical analysis showed that the CC genotype cows were characterized by higher milk yield as compared with cows with the heterozygous genotype, and the latter were characterized by a longer calving interval. The results were not confirmed statistically.
