Summary. During pregnancy, the body of cows is very sensitive to unfavorable environmental factors, for example, errors in feeding and maintenance, which negatively affects their health, manifested by metabolic disorders, the development of pathology of the birth and postpartum periods. For the research, Holstein cows were selected two months before calving and were divided into two groups: control and experimental. Blood samples were taken from all cows, followed by a study of the biochemical composition on the first and 14 days of the experimental period, and the presence or absence of pathology of the birth process and the postpartum period was also taken into account. The results of the research have shown that impaired mineral and protein metabolism in cows in the last trimester of pregnancy is an unfavorable factor contributing to the development of retained placenta, endometritis and mastitis. The applied scheme of prophylaxis in experimental animals promoted activation of the liver and protein metabolism, as well as a decrease in the incidence of endometritis and mastitis in the postpartum period.

Keywords: cow, holstein breed, blood, biochemical studies, retention of placenta, mastitis, endometritis, selenium, tissue preparation, prevention.
