Summary. Improved obstetric and mammological medical examination of cows during the dry period makes it possible to determine the nature of the prevailing pathology, to establish its main causes, and to present specific proposals for the implementation of preventive and therapeutic measures based on the real capabilities of the farm. Ultrasound examination made it possible to diagnose changes in the tissues of the udder caused by pathologies of non-infectious etiology: edema, bruises and associated hematomas. In addition, we were able to determine the state of the alveolar tissue, the size of the milk passages and cisterns. Therefore, sonography makes it possible to diagnose pathologies that occur as a result of incorrect start-up of lactating cows. The maintenance of cows in the last trimester of pregnancy should be based on a deep knowledge of the biological characteristics of cattle, clearly defined conditions for feeding and keeping animals. Compliance of the start-up technology and the interlactation period has a positive effect on the course of calving, the safety of the offspring, the postpartum period, milk flow and the quality of the received milk. It is desirable to include an analysis of the feeding and animal housing in the complex of measures during the obstetric and mammological medical examination of cows during the interlactation period. The proposed obstetric and mammological medical examination of cows during the interlactation period allows us to determine the nature of the prevailing pathology, to establish its main causes, to present specific proposals for the implementation of preventive and therapeutic measures, based on the real possibilities of the economy.

Keywords: large horned cattle, cows, interlactation period, breeding stock, udder, obstetric and mammological study, feeding, animal housing, ultrasound investigation, blood tests.
