What is Bio Preg Check?

BioPRYN® (Pregnancy Ruminant Yes/No) is a pregnancy detection procedure in cattle. It measures the presence of Pregnancy-Specific Protein B (PSPB) in the blood circulation of the animal. The PSPB is a protein that is produced by the placenta of the growing fetus. BioPRYN® begins with collection of a blood sample (2cc) from the animal. The samples are then shipped to a laboratory where an enzyme-linked immunosorbent assay (ELISA) is performed. Reports may be downloaded directly into ranch management software. Using BioPRYN® assures accuracy. When the livestock producer or veterinarian draws blood samples from the animal(s) at the correct time (28 days post natural breeding, 28 days after AI, and 34 days of embryo life in the case of embryo transfer) after breeding and 72 days after calving in cattle, the pregnancy question is answered within 27 hours after testing begins!
