INFLUENCE OF THE GENOTYPE OF PRODUCER COCKS BY PROLACTIN (PRL) AND GROWTH HORMONE (GH) GENES ON THE GENOTYPE OF DESCENDANT CHICKS

Using poultry of the K3 line of the Rhode Island White breed, the influence of the genotype of breeding roosters on the prolactin (PRL) and growth hormone (GH) genes on the genotype of offspring hens was studied. An increase in the frequency of occurrence of the C allele in offspring hens from 0.500 to 0.621, the presence of a large number (54.6%) of mutational changes with the replacement of the B allele by the C allele, the high occurrence (40.7%) of the CCAA genotype inherited from breeding roosters indicate prospects for breeding the K3 line in terms of egg productivity.
