Abstract
The article presents the results of the effectiveness of methods for diagnosing the uterus in cows on different days after calving. In the postpartum period in cows under conditions of weakened immunity and dystocia, inflammatory processes in the uterus can develop, most commonly manifesting in clinical and subclinical forms of endometritis. Our research shows that the rectal diagnostic method is impact in the first 30 day in milk (DIM), particularly when clinical signs are evident. In 60 DIM, the vaginal method demonstrated about 58.8% effectiveness, by the using on "Metrasta-tum" device determine the degree of uterine involution and assess the obtained dis-charges. After 61 DIM the probability of detecting endometritis by laboratory methods increased from 6.3 to 25%. In this study, laboratory methods such as the Nagornyi-Kalinovsky test (NKT) and the Whiteside method (WM) were employed. Subclinical forms of inflammatory processes in the uterus in the absence of obvious visible signs imply the use of laboratory methods based on identifying inflammatory markers. The definition of effective and useful methods is an urgent task and requires additional re-search.
