How to draw blood from cattle
What is BioPRYN
BioPRYN is a pregnancy detection tool to detect pregnancy in cattle, goat, sheep, and horses. BioPRYN offers a safe, accurate, and easy alternative for confirming pregnancy in ruminants and horses. BioPRYN measures the presence of pregnancy-Specific Protein B (PSPB), a protein only produced by the placenta of a growing fetus, in the blood circulation of the animal.
The PSPB or Estrone Sulfate in horses is produced by the placenta, and therefore pregnant animals will have the protein in their blood. This makes the test more accurate than earlier attempts at pregnancy diagnosis which evaluated blood or milk for progesterone or other hormones that can occur in normally cycling animals. This technology works on all ruminants, including cattle, sheep, goats, bison, deer, elk, and moose. It also works on horses.
BioPRYN is greater than 99 percent accurate when the test identifies animals at least 30 days post-breeding as not pregnant with less than 1 percent showing false-non pregnant.
