Clinical morphological reasoning of the diagnosis of subclinical cows endometritis

Abstract

The project presents the results of the clinical and morphological substantiation of the diagnosis of endometritis in cows. The scientific and production part of the experiment was carried out by the method of selection of analog groups, taking into account the reproductive age and live weight, according to generally accepted methods. Two groups of animals were formed. Group one - cows with subclinical endometritis, group two - with no signs of this pathology, which is morphological control. Of these, seven animals were healthy and thirteenth with signs of endometritis. Of these, pathology in an acute form was detected in three animals, in a latent form in ten animals. The formation of a group of animals with a normal course of the postpartum period was carried out on the basis of techniques, including examination of the external genitalia and rectal examinations. General clinical indicators were also taken into account: temperature, pulse and respiration. The studies were carried out on the basis of the Department of Anatomy and Histology of Animals named after Professor A.F. Klimov FGBOU VO MGAVMiB - MBA named after K.I. Scriabin, as well as in ZAO Povadino breeding plant. Hematological studies were carried out on the basis of the Chance Bio laboratory. A comprehensive methodological approach was used in the work, including clinical examination of animals, macroscopic morphometry, anatomical preparation, morphological blood tests, statistical analysis of the obtained digital data. The normative morphological parameters of the uterus in black-white Holsteinized cows were established as the baseline for assessing the nature of structural changes in the organ with subclinical endometritis. Revealed pathognomonic morphological signs of the uterus in subclinical endometritis, expressed in an increase in its cavity and horns, the accumulation of exudate in them, in the swelling and dullness of the endometrium. In the course of the conducted hematological studies, the manifestation of an inflammatory reaction was noted, expressed in an increase in the number of leukocytes, stab and segmented neutrophils and monocytes. The article presents the clinical and morphological substantiation of the diagnosis of subclinical endometritis, based on a comprehensive assessment of changes in the morphometric parameters of the uterus and hematological changes occurring in the body.
