POLYMORPHISM OF THE GENE BOLA-DRB3 UKRAINIAN BREEDS OF CATTLE

Abstract

Polymorphism of alleles of exon 2 of the BoLA-DRB3 gene of three Ukrainian cattle breeds was investigated. the cows of the Ukrainian black-pied dairy breed detected 32 alleles out of 54 possible, which were typed using the PCR-RFLP method and 74 genotypes. In the red-pied dairy breed population, the allele spectrum consists of 22 alleles and 35 genotypes are identified. 28 alleles of BoLA-DRB3.2 were established for two studs of aboriginal Ukrainian gray breed, of which five non-nominated PCR-RFLP (* jab, * jba, * jbb, * nad and * nda). the received results are needed in further studies to establish associations between the alleles of the BoLA-DRB3.2 gene, diseases and utility-useful signs.
