Monitoring Influence of PGF2 , Estrogen and Oxytocin on α Postpartum Uterine Involution by Ultrasonography in Ewes

Abstract

The goal of this study was designed to investigate the effect of estrogen, oxytocin and PGFα on uterine involution post-partum (p.p). In addition, the times for ewes to go through involution by ultrasonographical rectal examination lead to assess the best time for insemination that ensure the highest fertilization rate to avoid endometrit is post-partum. This study carried out at sheep and goat's improvement station, state board of agricultural research in Agargof, during November 15,2020 to April 15, 2021 This study involved 30 ewes of 2-4 years old and . 50-65kg body weight. Blood was collected to estimate progesterone concentration and the role of ovarian activity. Results showed a gradual decrease in uterine lumen and uterine diameter. The uterine horn diameter, at different weeks of post-partum in groups treated PGF2 was α40.63 mm at first week and decrease14.22 mm The uterine involution in ewes treated with PGF2 on post-partum, facilitate uterine involution . α process in ewes and lead to remove uterine fluid (lochia) and decrease uterine size, and uterine lumen. The study proves progesterone concentration as indicator to detect Ewes' post-partum ovarian activity. The current study reveals that the ultra-sonographic approach is a viable option for uterine involution management.
