BioPRYN

All Services

Using BioPRYN assures accuracy. The assay is greater than 99 percent accurate when an animal is categorized as open, giving producers confidence to administer prostaglandin and restart a synchronization program to artificially inseminate (AI), turn their females out with the herd bull or cleanup bull, or cull the animal. The false-pregnant (false-positive) rate for the test is approximately 5 percent. It is presumed that a portion of this variance is due to early embryonic death, which is a challenge regardless of which method is used for pregnancy detection.
