Development of genetic markers for productivity traits in beef pedigree cattle of Auliekol and Kazakh white head breeds
This article presents the results of screening in populations of Auliekol and Kazakh White Head breeds on the presence and frequency of polymorphic variants of genes of somatotropin cascade bPit-1, bGH and bGHR to assess their potential as genetic markers for beef productivity traits. According to obtained data it was noticed that observed genotype frequencies followed theoretically expected ones according to Hardy-Weinberg rules and their effect on meat productivity traits was determined.
