Fetal Ultrasonographic Parameters for Gestational Age detection in Maraz Goats

Abstract

Background: Ultrasound considers one of most common tools that used and depended in pregnancy diagnosis in farm animals and also to assess many parameters of reproductive performance Aims: The goal of this study was to conduct relationship between Crown-rump length (CRL), Biparietal diameter (BPD) and age of gestation in Maraz goat. Thirty Maraz does non-pregnant were synchronized to inducing estrus by utilizing vaginal sponges for about 12 days and followed by injection of 600 IU of PMSG hormones withdrawing the sponges and naturally served to obtain pregnancy. 73.3% (22/30) of the synchronized goats became pregnant, all synchronized goats were scanned every five to ten days beginning from day 30 to 95 of gestation transrectally (TR) with linear-probe (4-9 MHz). Results: This study conducts a significant relationship of each CRL and BPD with advance age of gestation period. The CRL and BPD increased significantly (P≤0.05) with the progress of pregnancy
Conclusions: The CRL and BPD are crucial parameters that could be useful and depended for follow the advance of gestation period by ultrasonic technique in goats.
