Ultrasonographic evaluations of early pregnant Surti buffaloes revealed that the uterine fluid was visible on Day 18 of pregnancy, yet this was not a sure sign of pregnancy. The amniotic vesicle could be detected by Day 26 and was a sure signof pregnancy. The embryo appeared on Day 26 but with clarity on Day 30. Fetal heart beats were visible from Day 26 and increased significantly (p less than 0.05) from Day 42 compared to Day 30, 34 and 38 of gestation and remained elevated till Day 62of gestation. The crown rump length (CRL) of the embryo / fetus could be measured using inbuilt callipers starting from Day 30 till Day 58.
