Abstract

The paper evaluates the effectiveness of artificial insemination of cows with sperm containing molecular hydrogen. The study was conducted on black-and-white cows of the second lactation. Two groups of animals were formed according to the principle of analog groups (control and experimental), with 50 heads each. The cows of the control group were inseminated with sperm frozen in a BioXcell medium, and the animals of the experimental group were inseminated with sperm frozen in a BioXcell medium with molecular hydrogen. To assess the initial functional state of the body, clinical studies and a comprehensive obstetric and gynecological examination were conducted before the start of the experiment. Insemination of cows was carried out by a group method by synchronizing sexual hunting according to the "Ovsinh" scheme. The effectiveness of insemination was evaluated on the basis of rectal ultrasound examination data on days 35 and 90 after insemination. The obtained results showed that the use of molecular hydrogen in the composition of the medium for diluting the seed makes it possible to increase the fertilizing ability of bull sperm and increase the percentage of pregnancy of cows during artificial insemination. Thus, the inclusion of molecular hydrogen in the composition of the solution for diluting the semen of cattle is advisable.
