Abstract
in English, French

The objective of this study was to evaluate a commercial blood test (DG29) for pregnancy in cattle. Compared with ultrasound, the sensitivity of the assay for detecting pregnancy around day 30 post-insemination was 99.4% [95% confidence interval (CI): 96.1-100]. The specificity was 100% (95% CI: 84.7-100) in non-inseminated cattle, and 66.7%; (95% CI: 49.7-80.4) in inseminated nonpregnant cattle. Positive and negative predictive values were 92.6% and 96.3%, respectively, in a sample of inseminated cattle in which 80% were pregnant.

En comparaison avec le diagnostic échographique, la sensibilité du test autour du jour 30 post-insémination est de 99,4 % (95 % IC: 96,1–100). La spécificité était de 100 % (95 % IC: 84,7–100) chez les animaux non-inséminés, et 66,7 % (95 % IC: 49,7–80,4) chez les bovins inséminés nongestants. Les valeurs prédictives positives et négatives étaient de 92,6 et 96,3 %, respectivement, dans un échantillon de bovins dont 80 % étaient gestants.
