In 107 of the ewes, examinations were also made with a Doppler ultrasonic instrument. A diagnosis of pregnancy from smears was made on 2 criteria: (1) a predominance of large, nucleated, spherical cells; (2) aggregates of these cells. Based on the 1st criterion, the accuracy of positive and negative diagnoses of pregnancy was 45.9 and 82.8% resp. vs. 88.6 and 48.3% for the 2nd criterion.  aAnimal reproduction  aEwes  aPregnancy diagnosis  aSheep1 aFUKUI, Y.1 aONO, H.  tIn: WORLD CONFERENCE ON ANIMAL PRODUCTION, 5., 1983, Tokyo.
