Comparative Study between Ultrasound Linear Probe and Curved Probe in Pregnancy Diagnosis of Rabbits

Abstract

This study aimed to evaluate the accuracy of using 7.5 and 5 MHz frequency probe for early pregnancy diagnosis in rabbits by ultrasonography technique. This study was conducted on sexually mature, and healthy twenty five rabbits (5 males and 20 non-pregnant female) were used. Mating was allowed between males and females where isolation of one male and four female was performed in separated cage. Results: early pregnancy diagnosis was easily performed with high accuracy by ultrasonographic scanning using probes of 7.5 MHz frequency on day 7 post-coitum in the pregnant does. Furthermore, using probe of 5 MHz frequency for pregnancy diagnosis was only feasible at 15^th day of pregnancy. Conclusions: the use of the linear probe (7.5 MHz) was faster and more accurate in diagnosing pregnancy at an early age compared to the curved probe (5 MHz).
