Abstract

In the article, the authors assess the prospect of using genetic polymorphisms to predict resistance to diseases and a possible enlarge in chicken production level.
Using the PCR-RFLP method, we analyzed the SNP frequencies in the genes of myostatin (MSTN, or GDF-8), proopiomelanocortin (POMC), and dopamine receptor D2 (DRD2) in chickens of the pure lines of the Smena-8 broiler hybreed – B6, B7m / o (slow-feathering), B7b / o (fast-fledging) FSBI "Breeding and Genetic Center “Smena”. The relationship between the studied single nucleotide polymorphisms and the productive traits of chickens was determined.
The assessment of the possibilities of using polymorphisms to increase the resistance and productivity of linear birds.
