Abstract

The article presents data on the frequency of twins in dairy cows, an analysis of cases of postpartum pathologies and the results of treatment and preventive measures in an agricultural enterprise in the Volgograd region. The work was carried out in the Limited Liability Company "SP "Donskoye" of the Volgograd region on Holstein cows with a milk productivity of 8,000-10,000 kg. At the first stage of the work, an analysis of the level of multiple pregnancy in cows in the herd was carried out, for this purpose, indicators of zootechnical and veterinary records and reporting for 2022-2023 were used. Ultrasound examination was used to determine twinning in cows. Cows with multiple pregnancy were monitored until parturition. Animals identified with pathologies of the genital organs in the postpartum period of multiple pregnancy, depending on the nature of the pathology, were subjected to treatment. The results of the study of the twinning rate in cows in the agricultural enterprise of the Volgograd region show that the number of twins in the total structure of calvings for the analyzed periods amounted to 4.2-2.4%, respectively. It was found that the level of diseases in the studied cows with uterine subinvolution was 37.2%-24.7%, placenta retention - 22.0%-27.2%, endometritis 34.0%-39.5%, respectively. The effectiveness of 1 treatment regimen for endometritis in the postpartum period in cows was determined. The study of the phenomenon of multiple pregnancy in cattle seems to us to be a promising direction that allows us to develop measures to reduce unfavorable factors during twin pregnancy, as well as to avoid various negative phenomena associated with twinning.
