Valoración de la citología exfoliativa vaginal, como método de diagnóstico del ciclo estral en cabras.

Abstract

In the Sheep, Goats and Camelids Academic and Research Center, an evaluation of vaginal exfoliative cytology was carried out in twelve adult mongrel female goat, with the aim of analyzing the presentation of the number of vaginal epithelial cells during the different stages of the estrous cycle. This cytological evaluation was carried out by means of a vaginal scraping of the mucous epithelium of the female reproductive system. Sampling was carried out with the help of a Citobrush brush to then be placed in the female's vaginal canal by opening the vulvar lips. Once the samples were taken, the vaginal epithelial cells that were found were evaluated through the microscope. In the investigation the following results were obtained. 92% of parabasal cells, 5% of intermediate cells, 2% of superficial cells and 1% of anuclear cells which were determined by the amount of cytoplasm and nucleus within their cell morphology. The parabasal cells showed to be those with the greatest quantity of nucleus and the anuclear cells with the greatest quantity of cellular cytoplasm. According to the results obtained, it can be concluded that in adult crossbred female goats, a greater quantity of parabasal cells is obtained when the female is under unfavorable environmental, nutritional, and management conditions, or is in a state of anestrus. But if these parameters are corrected, we can observe the cellular change from parabasal to anuclear, which are the cells of the heat stage.
