Clasificación de hallazgos endometriales en vacas con problemas reproductivos

Abstract

In the canton of Cevallos, located at 2908 meters above sea level in the Province of Tungurahua, 30 cows were examined, of which in their anamnesis they showed repetitions of estrus and abortions. To classify the endometrial findings, three diagnostic techniques were used: 1) vaginoscopy, which is used to show alterations in the uterine mucosa; 2) Cervico-uterine cytology, collected by Cytobrush to determine the presence of inflammatory cells especially polymorphic nuclear (PMN) and 3) endometrial histopathology, collected by Thoms-Gaylor clamp to establish the degree of endometrial injury. The results obtained at the macroscopic level determined that 14 cows presented a pale pink color at uterine level, 9 reddish colored cows and 7 cows with muco-purulent secretion. In addition, the degree of endometrial inflammation was classified by the presence of PMN, showing that 16 cows showed mild inflammation due to the presence of 1-5 PMN / field, 8 presented 6-10PMN / field and 6 cows revealed ˃10 PMN / field which indicates a severe inflammation. Injury damage was also cataloged resulting in 2 animals in category I, because it does not show any alteration; in category IIA 15 cows were obtained since they showed inflammation of the endometrium with cellular infiltrates in the luminal epithelium and compact stratum; in category IIB 11 cows were located since they revealed inflammation of the spongy and luminal layer of the endomery and in category III 2 cows were located because they showed a severe inflammation of both the luminal epithelium and the compact and spongy stratum, in addition to lymphatic gaps. Concluding that the techniques used are useful to diagnose endometritis in cows.
