ESTIMATIVA DA FASE DO CICLO ESTRAL POR CITOLOGIA VAGINAL EM CADELAS (Canis familiaris, LINNAEUS, 1758) DA REGIÃO DE ITUVERAVA-SP

Abstract

The estrous cycles of bitches are divided into successive and individual phases. The phases are: proestrus, estrus and metaestrus following anestrus. These phases can be differentiated by hormone or cytological examinations that permit estimating the fertility period, estrus cycle disturbances, and sexual inactivity. In this way, the present study has the objective to perform cytological vaginal examinations in bitches in order to identify the reproductive score of these animals during an anti-rabies vaccination campaign in the city of Ituverava, Sao Paulo. The results performed in 91 animals indicated an outcome of 14,2% in proestrus, 23,0% in estrus, 3,2% in diestrus, and 52,7% in anestrus.
