Join the thousands of farmers already taking advantage of modern-day cow pregnancy testing.

PregCheck30 offers the following:

  • 98% accurate at 30 days or even earlier
  • No stress or mess for you or your cows
  • Non-invasive
  • No lost production
  • No risk of disease transmission

  • PregCheck - the smart way to diagnose the pregnancy status of dairy cows

    •   Identify empty cows and re-join earlier. By shortening your calving interval you improve economic performance.
    •   Timely identification of empty cows allowing you to re-join quickly is a key component of a successful reproductive program.
    •   The highest rate of embryo loss occurs early in pregnancy, however embryo/fetal mortality can occur at any time through pregnancy.
    •   Following early pregnancy detection, monitoring is necessary to find out quickly if a pregnancy is lost.
    •   There is an economic impact of empty cows in mid to late lactation.

    Accurate and reliable
    Field trial data obtained prior to commercial release of the test demonstrated that the product is over 98% accurate at diagnosing pregnant and empty cows from a single milk sample, 30 days from joining and sometimes even earlier.

    Clean and non-invasive
    PregCheck means no mess for you and no discomfort for your cows. It also eliminates risk of disease and abortion that may result from invasive pregnancy testing.

    Stop culling pregnant cows and make better carry-over decisions
    PregCheck will help ensure you don’t cull pregnant cows – and avoid the associated costs. It also helps you make better carry-over decisions and more accurately allocate mating groups in batch mating systems.

    The following chart illustrates the typical change in protein levels during successful pregnancy.

    PAG levels through pregnancy

    PregCheck30 is a milk pregnancy test that measures a protein in a cow’s milk called PAG (Pregnancy Associated Glycoprotein) that ONLY comes from the placenta.

    Here’s a simple overview of how PregCheck30 works. For more detail, please visit FAQs.

    1.  Pregnant cows produce a protein called PAG. This protein comes from the cow’s placenta (and ONLY from the placenta) and is released into a pregnant cow’s blood stream and milk.
    2.  As a cow’s pregnancy progresses, the concentration of the PAG protein increases.
    3.  The levels of PAG in milk reflect the amounts produced by the placenta.
    4.  PregCheck30 is able to accurately measure the concentration of this protein from a cow’s milk sample.
    5.  After 30 days post-mating, there will be significant levels of the protein in the cow’s milk - but only if it’s pregnant.
