Abstract

AIM: Evaluation of the features of the genomic architecture of Ayrshire cattle in Russia in comparison with other dairy populations of Bos taurus.

MATERIALS AND METHODS: Using bioinformatic analysis of 42628 SNP markers obtained during genotyping using the BovineSNP50_v3 BeadChip medium density microarray, the features of the genomic architecture of five Bos taurus populations of different breeds were revealed.

RESULTS: The domestic population of Ayrshire cattle was characterized by the lowest heterozygosity (Ho = 0.335, He = 0.339) and insignificant inbreeding (Fis = 0.010) MDS analysis. At the same time, domestic breeding animals formed a separate group within a single cluster of Ayrshirs.

CONCLUSION: The Russian population of Ayrshire cattle is distinguished by a unique genome architecture, while retaining the genetic variants of the Finnish Ayrshire cattle and minor traces of Holstein gene pool.
