Hormonal therapy for ovarian dysfunctions in high-productive cows

Abstract

The analysis was made of culling data in the farm of the Udmurt Republic. As a result, it was found that the animals are eliminated due to gynecological and limb diseases. They make up 19–24 % and 18–31 % respectively. Analyzing the results of gynecological clinical examination of cows, we found a predominance of ovarian diseases 32–36 %, as well as endometritis 28–30 %. The ovarian dysfunction progresses mostly. This can be attributed to an increase in the productivity of cows in the Udmurt Republic over the past 5 years from 5601 to 6250 kg per 1 cow. In connection with an increase in the incidence of ovaries, the calf yield per 100 cows decreases from 88 to 85 %. Causes of ovarian disease can be diseases of the birth and postpartum period. For the treatment of ovarian hypofunction, 3 schemes were used for anestral and reactive reproductive cycles. Often, the cause of ovarian hypofunction is uterine pathology; drugs that have a therapeutic effect on the uterus are included in the scheme.
