VAGINAL CYTOLOGY PROFILE FOR ACCOMPANIMENT TO ESTROUS CYCLE IN BREED SANTA INÊS EWES

Abstract

The objective of this work was to establish a vaginal cytological profile in ewe of the Race Saint Inês, during a complete estrous cycle. Five created cyclical females in half-intensive system had been selected, in the Farm Rocks Saint, Araguaína, TO. The vaginal smears had been made daily during the estrous cycle, detected for a ruffian. One was confectioned vaginal smears for female, in dry glass slides to the ambient temperature and settled in alcohol 95% and in followed. They had been staining by the fast panótico method. The glass slides had been observed to the optic microscope with increases of 10 x and 40 x for counting of 100 cells and visualization of the morphologic and staining characteristics of the epithelial cells to the long one of the estrous cycle. The changeable phases of the estrous cycle – proestrous, estrous, metoestrum and diestrum – e types cells – basal, parabasal, anuclear superficial –, intermediate and had been studied by means of ANOVA, to the level of probability of 5% for the test of Tukey. The some types cells of the vaginal epithelium had been found to the long one of the phases of the estrous cycle and evaluated four types of cells: nuclear superficial, intermediate, basal and parabasal. In the phase of estrous a difference was noticed statistics of the anuclear superficial cells on the too much types (P<0,05). One concluded that through the exfoliation vaginal cytology it can be differentiated the phases of the estrous cycle in ewe of the race Saint Inês.
