The work is aimed at studying the genetic polymorphism of the milk protein loci in Holstein and Black Pied breeds and determining the genetic distance and similarity of these breeds. A total of 371 milk samples were collected from cows from two breeding farms. The population allele pool for the lactoproteins aS1-CN, b-CN, k-CN, b-LG was determined. Polymorphism was revealed in all loci. The most expressive one was the locus aS1-CN. Three alleles (A, B, C) were found in the population of Holstein breed and 4 alleles (A, B, C, D) in the population of Black Pied breed. The locus b-CN had two allelic variants: b-CNA and b-CNB, the locus b-CNA recording a higher frequency in both populations. The locus k-CN had two alleles (A and B), the allele A recording a higher occurrence in the population of Holstein breed. The value of genetic similarity between the studied populations was of 0,7714. |
