Reproductive Performance of your Dairy Cows
Reproductive performance is vital to all successful dairy operations and the earlier pregnancy is detected the better.
GestaLab Milk Pregnancy Test
Milk pregnancy testing is an easy, fast and affordable option for confirming pregnancies in your herd. Achieve higher pregnancy rates, optimum calving intervals and reduce days open by detecting open cows quickly and returning them to service.
Accurate and Cost-effective
The GestaLab pregnancy test can be processed during routine milk recording or between tests at your convenience. Using ELISA laboratory technology, the test is highly accurate and measures the level of pregnancy-associated glycoproteins (PAGs) present in a milk sample.
Cow Pregnancy Results
GestaLab reports and test results are easy to understand. You can test as early as 26 days post-breeding. Most producers will perform a confirmation test (re-check) between 40 and 80 days and some will test pre-dry-off and avoid a costly open dry cow surprise.
Assessing the reproductive performance
The reproductive success in your herd is best determined from the analysis of data. Through milk testing and milk recording, we can provide you with tools to be able to assess and monitor reproductive parameters. With your consent, we can also make this information available to your team of advisors.
