The aim of this study was to examine the effect of estradiol (E2) and oxytocin (OT) treatments
on the cervix dilation of three breeds of Iranian ewes. Cervix dilation was measured by …

The objective of this study was to determine the effect of exogenous oxytocin (OT) treatments
on the cervix dilation of three breeds of Iranian ewes. Cervix dilation was measured by …

Cervical anatomy in ewes usually prevents nonsurgical, intrauterine AI and transcervical
embryo transfer (ET), which limits their commercial use in sheep. This study was conducted …

In sheep industry, pregnancy rate after artificial insemination (AI) declines due to the
complex anatomy of the cervix in ewes, such that it might prevent effective intrauterine …

Background A major limitation in the application of assisted reproductive technologies in
sheep arises from the inability to easily traverse the uterine cervix. The cervix of the non …

Experiments were conducted to determine whether exogenous estradiol-17 β (E2) and
oxytocin (OT) can be used to improve transcervical (TC) embryo transfer (ET) procedures for …

Cervical relaxation (CR) was performed in ewes during diestrus, to prospect a feasible
protocol for non-surgical embryo transfer (NSET). In Trial 1, naturally mated ewes (n= 13) …

This study compared the effects of intravaginal and intravenous routes of oxytocin (OT)
administration in 46 oestrous‐induced Santa Inês ewes (6‐day treatment with progestin …

An oocyte recovery procedure was developed and evaluated to determine whether a
transcervical embryo recovery procedure is feasible with our method, which includes …

Objective: To determine the effect of different cervical dilators on cervical dilation and
reproductive performance of fat-tailed ewes. Methods: In experiment 1 140 ewes were …
