What It Is

What It Is

BioPRYN® is a pregnancy detection tool for use in cattle. It measures the presence of Pregnancy-Specific Protein B (PSPB) in the blood circulation of the animal. The PSPB protein is only produced by the placenta of the growing fetus. Cows and heifers must be at least 28 days post-breeding and cows must be at least 73 days post-calving. There is a chance for a false positive if the residual PSPB has not cleared the maternal system from cows that have calved more recently than 73 days ago.
