| Popis: | The present study investigated the hormonal profile and expression of prostaglandin F2? (PGF2?), oxytocin and estrogen receptors in uterine tissues of postpartum cows treated with cloprostenol. Twenty HolsteinZebu crossbred cows were treated with saline solution (treatment CONT) or cloprostenol (treatment CLO), both administered two and five days postpartum. Blood samples were collected on days two, seven, 14, 21 and 28 postpartum for progesterone, PGF2? metabolite (PGFM) and estradiol determination, and endometrial biopsy was performed in order to quantify the expression of oxytocin receptor (OXTR), prostaglandin F receptor (PTGFR) and estrogen receptor 1 (ERS1) genes. In the CLO treatment, expression of OXTR was reduced (P0.05) between treatments was found for PTGFR and ERS1 expression. Estrogen concentrations increased progressively until day 14 (P0,05). Os níveis de PGFM foram altos durante todo o estudo. Conclui-se que a administração de cloprostenol nos dias dois e cinco pós-parto parece diminuir a expressão de OXTR no endométrio em vacas mestiças.
