Immunogenetic polymorphism in cows of black-and-white breed from FSUE "Streletskiy" in Orеl region

Of particular relevance in the breeding work is the use of blood groups as signal markers for the study of hereditary characteristics and potential capabilities of livestock. To reflect the selection processes occurring in the breed and herd, it is necessary to study immunogenetic polymorphism. In this regard, the study studied alleles of blood groups in 11 locus systems, as well as the dynamics of their occurrence. The result of this study, the herd FGUP "Streletskaya", is that 50% of cattle were carriers of desirable QUOTE 14A1,G2,Y2,O4,Q',E'1,C1,W,X2,H',FF,V"> alleles that may be genetic markers of milk productivity of cows.
