Abstract

The present research was developed in order to try a method of pregnancy diagnosis in goats, through the differentiable characteristics of the vaginal epithelium. A total of 55 goats were used. Materials for histologic and cytologic examination were taken from the anterior region of the vagina with a 10-day interval, initiating by day 20 until day 90 after mating. Biopsies were processed using standard techniques and stained with H.E. and PAS. Vaginal smears were stained by PAPANICOLAOU’s technique. During pregnancy, the epithelium was recorded as immature, being composed of 4 to 5-cell layers, with parabasal or low intermediate cells on the surface. The non-pregnant epithelium was composed of 8 to 10 cell-layers, showing high intermediate or superficial cells on the surface. This difference allowed to diagnose pregnancy and non-pregnancy status. Vaginal smears showed low intermediate, parabasal and cuboidal cells for both pregnant and non-pregnant groups.
