Abstract
This article reflects the results and significance of a study of the prevalence of obstetric and gynecological diseases in dairy cows and heifers in the West Kazakhstan region. According to the results of the research, obstetric and gynecological pathologies were detected in 157 heads (34.6%) of the 445 cows and heifers examined. According to the results of the conducted studies, uterine subinvolution, vestibulovaginitis and inflammation of the uterus (endometritis) are widespread among obstetric and gynecological pathologies. Among the forms of uterine inflammation, the acute course of the disease is more common in terms of prevalence compared with chronic and subclinical forms. The causes of inflammation of the uterus were the following pathologies: vestibulovaginitis, retention of the placenta and subinvolution of the uterus. Persistent corpus luteum, cyst and hypofunction of the ovaries were also identified, which prevented optimal fertilization of cows and heifers, which led to permanent infertility of the animals. Intensive development of dairy farming is obvious that the indicators of productivity and reproduction of livestock directly depend on it, therefore, monitoring the normal condition of the reproductive organs of cows and heifers, that is, timely obstetric and gynecological medical examinations, strict compliance with zoohygienic and veterinary requirements plays an important role in the dynamic development of animal husbandry.
