title: Evaluation of an ultrasonic Doppler probe for pregnancy diagnosis in cattle.
abstract: The use of an ultrasonic Doppler probe for pregnancy diagnosis was evaluated. Data from the examination of 1115 cattle were analysed. Comparison of the probe with manual rectal palpation by an experienced clinician yielded a sensitivity of 92.8 +/- 1.6% (+/- 95% confidence interval) and a specificity of 75.8 +/- 7.4%. This level of accuracy was found to be insufficient to recommend the probe be used by farmers for the diagnosis of pregnancy.
