Two dimensional trans-rectal ultrasonographic studies in early pregnant murrah buffaloes

Abstract

Two dimensional ultrasonographic studies were conducted in six pregnant Murrah buffaloes using 5.0-7.5 MHz frequency rectal probe twice a week from day 18 to 60 days followed by weekly interval up to 90 days post insemination. Two dimensional images of antenatal fetal organs particularly fetal stomach, eye, limbs, heart, umbilical cord, thorax, liver and placentomes were imaged and variations in size of placentome, stomach and crown rump length were measured. Fetal heart beat was measured from day 26 to 90 which decreased with advancement of gestation. From the present study it may be concluded that early pregnancy can be diagnosed ultrasonographically through trans-rectal approach by day 26 post insemination.
