What is bioPryn®?

BioPRYN (Pregnancy Ruminant Yes/No) is a pregnancy detection procedure for cattle, sheep, elk, goats, bison, and deer. It measures presence of Pregnancy-Specific Protein B (PSPB) in the circulation. PSPB is a protein from the placenta. BioPRYN begins with collection of the blood sample from your cow. Then you ship the samples to Central Florida Large Animal Veterinary Services where an enzyme-linked immunosorbent assay (ELISA) is performed. Reports are available within 27 hours of lab setup and may be downloaded directly into dairy management software. Using BioPRYN assures accuracy. When the manager or veterinarian draws blood samples from the cows at the correct time (28 days) after breeding and 90 days after calving, the pregnancy question is known within 27 hours.
