Changes in blood flow to the umbilicus, placentomes, and uterus in Surti buffaloes during complete gestation

Abstract

With an objective to record the vascularity changes in the umbilicus, placentomes dimensions, and blood flow to the uterus, Surti buffaloes (n=42) were inseminated during natural estrus during the breeding season and scanned by transrectal B mode and color flow mode ultrasonography every 3-4 days till Day 90 of gestation and then at 15 days interval for the complete gestation in the buffaloes that were pregnant (n=24). The umbilical cord color Doppler wavefronts could first be obtained on Day 46 and became increasingly distinct thereafter. The placentomes could first be identified at Day 76 of gestation. The placentome diameters increased from Day 76 till 8th month with significant increases (P
