Abstract
The present study was conducted in buffaloes which were maintained at experimental
animal sheds of Animal Reproduction Division, IVRI, Izatnagar. All the experimental
buffaloes (n=6) were observed for onset of estrus using a teaser bull and visual signs
of estrus followed by rectal examination twice daily. Animals detected in estrus were
inseminated using frozen semen of Murrah buffalo. The inseminated buffaloes were
allowed for real time B-mode ultrasonographic examination at 10 days interval starting
from day 20 to 120 of pregnancy. Monitoring of embryonic development was carried out
by viewing embryonic vesicle diameter (EVD), Crown Rump length (CRL), embryonic
heartbeat, skull and placentome through ultrasonography. The mean diameter of EV was
0.52±0.12, 1.56±0.16, 2.94±0.07, 3.80±0.14 and 6.37±0.15 cm on day 20, 30, 40, 50
and 60 of pregnancy, respectively. EVD increased with advancement of pregnancy and
reached around 6.37±0.15 cm on day 60 of pregnancy.
