Conteúdo: 	The detection of ovulation is of great importance for the use of reproductive biotechnologies in small ruminants. The ovulation is efficiently determined by ultrasound (US), equipment that is not always  available and of relatively high cost. Therefore, the aim of this study was to identify the efficacy of vaginal cytology as a tool to determine the ovulation time in these species. The study was carried out during the non-breeding season, in Coronel Pacheco, Minas Gerais (21°35'S and 43°15'W). In sheep, the standard chosen was anucleated, but it had a high CV (23.7%), which led to non-high accuracy (66.7%). Therefore, PPV and NPV were 26% and 88%, respectively; the specificity was 45% and 64% at 24 h and
12 h before ovulation respectively; and finally, the sensitivity at the moment of ovulation was 55%. It can be concluded that the vaginal cytology may be an efficient tool to determine the moment of ovulation in goats, however it is less accurate in sheep.
