Pulsed wave Doppler ultrasonographic images of the fetal heart (FH) at days [(-30; A), and -10 (B)] before parturition in a Zaraibi goat with the automatic calculation of both Doppler indices (RI and PI), S/D ratio, and BFR(bpm). The red star showed the maximum systolic point of velocity (MSV; cm/sec), while the blue asterisk showed the end point of velocity due to relaxation (EDV; cm/sec). RI = resistive index, PI = pulsatility index, S/D = systole/diastole, and BFR = blood flow rate
