Forty-two goats maintained at the university sheep breeding farm (SBF)
Alusteng were tested for pregnancy using a medata type of ultrasonic
equipment, with a rectal probe, working on 'Doppler principle'. Out of
the 32 goats predicted pregnant, 25 goats delivered normally, showing
an overall accuracy of 78.1%. The accuracy of different sounds audibl
e for predicting pregnancy was 100%, 100% and 72% for foetal heart bea
ts (FHB), umbilical blood flow (UBF) and middle uterine artery sounds
