BioPRYN Offers Fool Proof Pregnancy Detection

September 27, 2010 09:11 PM
 

BioPRYN, a 2 cc blood test taken from the tail head, can find open cows with nearly 100% accuracy with results now available the same day the lab receives the sample. The cost for same day notification is $3.50/sample plus shipping, almost less than the value of one extra day open on many farms.

BioPRYN is an ELIZA test which measures the presence of Pregnancy-Specific Protein B (PSPB), which originates in the placenta of pregnant animals and circulates in the blood before the third week after conception. PSPB levels reach high enough levels 30 days after breeding to be accurately detected by BioPRYN. Residual PSPB from the previous pregnancy are also present, so the test cannot be performed before 90 days after calving.

Once that 90-day threshold is reached, however, the test is extremely accurate, able to identify 99.9% of open animals and 93% to 95% of pregnant animals. “The test’s accuracy gives cattle breeders confidence to return cows to a hormone-based breeding program knowing there is little to no chance they will abort cattle that are actually present,” says Garth Sasser, president and research director for bioTracking, which markets the test.

The test is available in 28 labs across the United States. For more information, click here.
