Abstract

[Extract] A 3-year-old Holstein Friesian cow from the Rayner Dairy Research and Teaching Facility, University of Saskatchewan, was bred successfully by artificial insemination at 135 days in milk (DIM) during the first lactation. Pregnancy was diagnosed at 168 DIM and confirmed at 196 and 238 DIM via transrectal ultrasonography. At 278 days of gestation, the cow delivered a healthy heifer calf that weighed 40 kg followed by the expulsion of an abnormal mass.
