Avaliação da dinâmica folicular e microbiota vaginal de acordo com a fase do ciclo estral em éguas.

Abstract

The equine species has its own characteristics, requiring accurate and specific knowledge regarding the events that involve ovulation, so that an appropriate reproductive management for this species can be established. The aim of the present study is to evaluate the ovarian follicular dynamics and to classify the degrees of uterine edema, as well as to evaluate the vaginal microbiota of mares in different phases of the estrous cycle. The objective was to observe population differences between the microorganisms that colonize the vagina in the respective estrous cycle phases. For this, daily ultrasound examinations of the uterus and ovaries were performed. In the ovaries, follicles were identified, counted and measured daily as a means of monitoring their growth dynamics and biological material was collected from each animal at specific times of the different phases. Thus, it was possible to follow the follicular dynamics, correlate the population growth of microorganisms with the different phases and the hormonal profile that governs each phase of the estrous cycle in the mare.
