DHI Cooperative is a certified BioPRYN® Lab

BioPRYN® (Pregnancy Ruminant Yes/No) is a pregnancy detection procedure in ruminant animals such as cattle, sheep, and goats. It measures the presence of Pregnancy-Specific Protein B (PSPB) in the blood circulation of the animal. The PSPB is a protein produced by the placenta of the growing fetus.

BioPRYN® begins with collection of a blood sample from the animal. The samples are then shipped to a laboratory where an enzyme-linked immunosorbent assay (ELISA) is performed. Results may be delivered via e-mail, fax, mail, or via phone call.

The livestock producer or veterinarian should draw blood samples from the animal(s) at the correct time after breeding. This timing ensures the accuracy of the BioPRYN test.

Cattle: At or greater than 28 days post breeding and 73 days post calving.
Heifers: At or greater than 25 days post breeding.
Goats and Sheep: At or greater than 30 days post breeding
