Distribution of chronic latent gynecological pathologies in dairy cows

The purpose of the research and production research in four breeding dairy farms of the industrial type was to establish the prevalence of chronic latent inflammatory processes of the reproductive organs, which lead to the loss of generative resources of dairy breeds of cattle. Analytical, structural-comparative, and statistical methods were used to perform the research tasks. The research data were obtained through a comprehensive examination of cows of the main milking herd (n = 552) and groups of culled cows due to numerous ineffective inseminations (n = 116), namely, ultrasound scanning of the tissues and uterine cavity and differential palpation of the fallopian tubes and gonads. Experimentally under in vivo conditions, it was established that compared to cows of the leading dairy herd in the culled group, the prevalence of symptoms of chronic latent endometritis was 33.93 % higher on average (P < 0.05) with significant fluctuations in different herds (from 12.06 to 67.51 %). A considerable spread of multiorgan gynecological pathology was established, namely the spread of chronic adhesive salpingitis, the symptoms of which in dairy cows were on average 39.40 % (with fluctuations of 7.18–83.65 %), which significantly increased among culled cows: +30, 77 % (in different farms from 52.17 to 90.00 %), which indicated the chronicity of long-term inflammatory processes in the endometrium and the area of the ciliated epithelium of the oviducts, which lead to chronic irreversible infertility (P < 0.01). An innovative methodological approach to improving diagnostics requires the introduction of innovations in the practical training methods of zoo-veterinary specialists and the requirements for preserving the generative and secretory functions of the reproductive organs of cows in gynecological therapy schemes.
