BioPRYN Pregnancy Test

What is BioPRYN ?

BioPRYN (Pregnancy Ruminant Yes/No) is a pregnancy detection procedure for cattle, sheep, elk, goats, bison, and deer. It measures the presence of Pregnancy-Specific Protein B (PSPB) in the bloodstream. PSPB is protein produced by the placenta. BioPRYN begins with the collection of a blood sample from your cow. Then you ship the samples to Laurel Hill 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 dairy manager or veterinarian draws blood samples from the cows at the correct time (28 days) after breeding and 73 days after calving, the pregnancy question is known within 27 hours.

CAE Testing

Caprine Arthritis and Encephalitis (CAE) is a retroviral infection of goats that may lead to chronic disease of the joints and on rare occasions (in goat kids less than six months of age) encephalitis (an infection in the brain). CAE is a widespread condition in goats across the world. The virus is directly connected to the production of white blood cells, so any body secretions which contain these cells are potential sources of infection for other members of the herd. Because there is no cure for CAE, it is best to avoid it altogether by use of proper herd testing and culling.

We use the cELISA test (Enzyme-Linked Immunosorbent Assay). This test is generally recognized as the most reliable test available.
The test requires 0.5 ml to 1 ml of serum (2-3 ml of whole blood using a red top tube)
Samples do not need to be sent with an ice pack
Results can be e-mailed, faxed, and phoned
Can be run in conjunction with pregnancy testing
The cost is $5.50 per sample
