Extract

The isolation of bovine pregnancy-associated glycoprotein (bPAG) from foetal cotyledons (Zoli, Beckers, Closset, Wouters-Ballman, Falmagne and Ectors, 1991) and the subsequent development of a radioimmunoassay for the detection of bPAG in the peripheral circulation of cows (Zoli, Guilbault, Delahaut, Ortiz and Beckers, 1992) could provide a simple and rapid means of accurately diagnosing pregnancy early in gestation. This study reports on the efficacy of using plasma bPAG concentrations as a means of pregnancy diagnosis in purebred beef heifers mated at a first or second synchronised oestrus compared to failure to return to oestrus and transrectal ultrasonography.
