and 28 days for adult cows, BioPRYN is greater than 99%
accurate for animals identified as open.

Using BioPRYN assures

management insights.

BioPRYN is over 99% accurate when
the test categorizes a cow as open

By identifying open animals with
99% assurance, producers and
veterinarians can confidently re-breed
or market open animals.

As a result, BioPRYN can be
implemented early in the pregnancy
(25 days post-breeding in virgin
heifers, 28 days post-breeding,
73 days post-calving in adult cows)
to save money.
