Consequences of “Holsteinization” of Ukrainian Black-Pied Dairy Breed by Gene BOLA-DRB3.2

Abstract: Introduction. The main direction of increasing the productivity of milk is to increase the proportion of heredity of the Holstein breed in the genotype of cows. Industrial breeds in Ukraine are improving due to the increase in the Holstein inheritance in the genotype of cows. The "holsteinization" of the most widespread domestic Black-and-White diary breed is intensively conducted. Currently, the percentage of heredity from Holstein is 90% or more. The negative effect of "holsteinization" appeared in reducing … Show more

“…In studies conducted in the Iranian population of Holstein bulls, seven most frequent alleles (BoLA-DRB3.2*08, *11, *16, *22, *24, *28 and *51) accounted for 80% of all found alleles (Parnian et al, 2006). Therefore, the abovementioned BoLA-DRB3.2 alleles were present in genotypes of Holsteinized cattle and were associated with traits considered introduced by the Holstein breed (Suprovych et al, 2017b). In domestic commercial breeds (Ukrainian black-and-white dairy, Ukrainian red-andwhite dairy), there were also found 6-7 alleles with frequency over 5%, but their overall frequency was somewhat lower -50.3% to 59.4%.…”
