Pregnancy Check And Fetal Development On Indonesian Domestic Rabbits By Means Of Ultrasonography

Abstract

This research is carried out to detect the earliest day of conception in Indonesian domestic rabbits by analyzing embryonic vesicle, body diameter and head diameter. The animals used for this research were six pregnant rabbits weighed between 1.75 – 3.90 kg. SonoDop ultrasound system with curved and linear transducers, ultrasound scanner (S-A5V) and Landwind Medical Mirror5 were used. The does were examined on day 5 after mating and every 2 to 3 days until they gave birth. On day 5, the embryonic vesicle size is 10.25 ± 0.96 mm and on day 10, the size is 22.50 ± 0.71 mm. The equation for it is x = y + 0.2/0.245. The average body diameter on day 18, 21, 24, and 29 were 0.96 ± 0.049 cm, 1.17 ± 0.025 cm, 1.49 ± 0.049 cm and 1.56 ± 0.026 cm respectively. The equation is x = y - 0.0021/0.0562. The average head diameter on day 18, 21, 24, and 29 were 0.79 ± 0.11 cm, 1.02 ± 0.08 cm, 1.22 ± 0.08 cm and 1.59 ± 0.02 cm respectively. The equation is x = y + 0.5073/0.0723. All x above is number of days. The earliest day of conception was determined on day 5 in Indonesian domestic rabbits.
