Abstract

The aim of present work was to evaluate the changes of cervico-vaginal epithelial cells and progesterone levels of nuliparous goats submitted to artificial photoperiod, in Middle-West of Brazil. Seventh Alpine and six crossbreed nuliparous goats were used, distributed in two groups: control (GC), maintained at isolated stall and submitted to natural light for the time of the year, and treated (GT), submitted to an alternate regime among natural and artificial light, for 24 hours and 35 uninterrupted days. Cérvico-vaginal content was collected, prepared on glass slides and differential cellular counts were carried out on Papanicolau smears. The progesterone concentration in blood serum was measurement by ELISA. Parabasal were the most frequent cell type present, followed by intermediate cells, mainly in the end of metaestrus and diestrus. Superficial cornified cells were present during proestrus and estrus. The cellular profile and progesterone concentrations oscillated in agreement with estrus cycle phase in control animals, but confuse on the begin of experimental period for treated animals. Cytological evaluation of cervico-vaginal content could be of value for a hormonal bioassay of estrus cycle of goats submitted to artificial photoperiod just after the adaptation period.
