Abstract

As a result of the study, new knowledge was obtained for the first time about the effect of the FXI locus polymorphism on the quality of reproduction in dairy cattle, the degree of influence of the FXI polymorphism on the frequency of development of pathologies of the reproductive organs, their clinical manifestation in individuals - carriers of the anomaly and healthy animals was established. The influence of the FXI locus polymorphism on embryonic and postembryonic mortality, clinical condition and safety of newborn calves in comparison with individuals without a genetic defect was determined.
