Abstract

A retrospective study was conducted in 15 Holstein dairy herds to determine the accuracy of detecting pregnancy with an ultrasound scanner between 22 and 40 days post-artificial insemination. The selected herds were on a computerized herd health program with the Faculty of Veterinary Medecine at the University of Montreal.
