PATHOLOGICAL AND MORPHOLOGICAL CHANGES IN COWS WITH ENDOMETRITIS
The results of studies connected with morphological and functional changes in the genital organs of cows, which are caused by different forms of postpartum endometritis and provoke symptomatic infertility in animals, are submitted in the article. In most of the diseased cows the postpartum catarrhal-purulent endometritis (69%) or catarrhal endometritis (28%) has been diagnosed. It is proved that the most severe complications are the result of the post-partum catarrhal-purulent endometritis. The disease is expressed as a deep lesion of the mucous membrane of cow uterus with dystrophic, necrobiotic and necrotonic changes. In cases of purulent inflammation of the mucosa membrane the uterus walls are being destructed and infiltrated with lymphoid cells, the structure of uterine glands is deformed. In the vascular and serous layers the artery lumens are being narrowed, this causing deficient supply of nutrients and oxygen to the cells. The study of the histostructural changes in cows, belonging to the class of animals with the desmohororial placenta type and being multiple by location, is of certain scientific and practical interest from the viewpoint of the degree of the disease severity estimation and assignment of long-term treatment.
