The Use of Power Mode Doppler Ultrasonography as a Predictive Tool of Early Pregnancy in the Mare

The mechanisms responsible for maternal recognition of pregnancy in equines are not fully understood. Previous research indicates that the migration of the embryo could have a local effect on uterine blood flow, stimulating vascular perfusion [1]. Moreover, this increase in blood flow during early pregnancy has been detected in other species including cows, sows and ewes although it is limited to the uterine segment that is in direct contact with the conceptus[2-4]. Color and pulse Doppler sonography has become one of the best reliable, non-invasive techniques for studies of uterine vascular hemodynamics [5,6].
