System of prevention of gynaecological diseases in high-productive cows under in a farm in the Udmurt Republic

Abstract

The purpose of the work is to develop a system for the restoration of the genital organs of cows after calving. We studied the therapeutic efficacy of drugs for the incidence of genital diseases of cows. The studies were conducted based on a complex of cattle of Black Motley breed at the facilities of Rico-Agro LLC in the Uvinsky district, Udmurt Republic. The average milk yield per lactation is 6250 kg. Most animals are susceptible to ovarian disease. The incidence of ovaries hypofunction increases annually. In the study of cows on the 60th day after calving, it was found that the uterus was ready for insemination in 86% of cows. However, the condition of the ovaries allows insemination of only 50% of the cows. The remaining animals needed treatment. The most common pathology was ovarian hypofunction. This is more common in highly productive cows and cows with a low body mass index. Three regimens for treating ovaries have been tested. The most effective Scheme 2 included Surfagon and an emulsion from ASD-2 and Tetravit. In the Scheme 2 group, 6 out of 8 cows were first successfully inseminated. It was established that using Estrofan on the first day after calving, it is possible to reduce the number of persistent corpus luteum.
