Abstract
SUMMARYDuring the period 1968–71, 417 ewes of various breeds were radiographed for pregnancy diagnosis during the period 60–95 days of gestation.Pregnancy per se was diagnosed by observing the presence or absence of a definite uterine outline with accuracies of 77, 97 and 100% of the period 60–70, 71–80 and 81 + days of gestation. During the periods 60–70, 71–80, 81–90 and 91 + days of gestation foetal numbers were diagnosed with an accuracy of 88, 94, 99 and 99 % respectively. Breed, size of ewe and number of foetuses carried did not affect the accuracy of diagnosis.
