Using the IDEXX Alertys OnFarm Pregnancy Test for Dairy Goats: A Convenient Way to Confirm Pregnancy Early
As dairy goat breeders, one of the most exciting (and sometimes nerve-wracking) times of the year is when our does are bred and we wait for the signs of pregnancy. Traditionally, this has meant relying on physical signs such as a change in behavior or the absence of estrus, but these indicators can sometimes be uncertain, and we may not know for sure until later in the pregnancy. That’s where the IDEXX Alertys OnFarm Pregnancy Test comes in – a game-changer for anyone looking for a quick, easy, and accurate way to confirm pregnancy in goats early on. At the Rafter O, we use these tests on our Mini Nubians to ensure early and accurate confirmation of pregnancy.
What is the IDEXX Alertys OnFarm Pregnancy Test?

The IDEXX Alertys OnFarm Pregnancy Test is a blood-based test that can be used to confirm pregnancy in dairy goats as early as 30 days after breeding. The test works by detecting the presence of the pregnancy-associated glycoproteins (PAGs), which are produced in the placenta of pregnant animals. This test is highly accurate and provides results within a short time, helping you to get reliable confirmation without waiting until your goat shows visible signs of pregnancy.
Why Use the IDEXX Alertys OnFarm Pregnancy Test?
- Early Detection: One of the biggest benefits of the IDEXX Alertys Pregnancy Test is that it allows for early detection of pregnancy – as soon as 30 days post-breeding. This early confirmation is crucial because it allows you to adjust your management practices and nutrition for pregnant does, ensuring they receive the proper care for a healthy pregnancy and healthy kids.
- No Need for Ultrasonography or Vet Visits: While ultrasounds are a common way to confirm pregnancy, they can be expensive and require a vet visit. The IDEXX Alertys test eliminates the need for these visits and is a cost-effective solution for breeders, as it can be done right in the comfort of your barn or farm.
- Reliable Results: The IDEXX Alertys OnFarm Pregnancy Test offers a high level of accuracy. You won’t have to second-guess whether your doe is pregnant. The test results are available in just a few minutes, giving you the confidence you need to plan for the coming kidding season.
- Convenience: The test is easy to use and doesn’t require specialized equipment or training. It’s a simple process of drawing a small blood sample and sending it to the lab for analysis. The test comes with clear instructions, and many breeders find it easy to use on their own.
- Peace of Mind: Knowing whether a doe is pregnant or not can reduce the uncertainty and stress of waiting for signs of pregnancy. It helps you to plan your breeding schedule and prepare for the next steps, such as creating a kidding pen and setting aside time for birthing.
How to Use the IDEXX Alertys OnFarm Pregnancy Test
- Collect the Blood Sample: The first step is to collect a blood sample from the doe. This is done by drawing blood from the jugular vein or the tail vein using a syringe. It’s important to handle the blood sample with care to avoid contamination. Invert the tube 10 times.
- Draw up the sample into the pipette.
- Dispense the full pipette of blood into the sample port.
- Add the wash solution within 2 minutes.
- Read results 5–20 minutes later.




The Benefits of Knowing Early
Using the IDEXX Alertys OnFarm Pregnancy Test helps you manage your herd effectively. When you know which does are pregnant, you can begin preparing for the birth process and make any necessary adjustments to your feeding and care routines. For instance, you may need to increase nutrition for pregnant does, provide them with supplements, or ensure that they have a quiet and comfortable place to rest as their due date approaches.
Additionally, knowing early allows you to make informed decisions about your breeding program. If a doe didn’t conceive, you can breed her again in the next cycle or try a different buck. The test also provides clarity for herd management, especially if you’re trying to maintain specific breeding goals or genetic lines.
Conclusion
The IDEXX Alertys Pregnancy Test is an invaluable tool for dairy goat breeders who want to ensure that they’re providing the best possible care for their does. It provides early, accurate pregnancy confirmation, is easy to use, and gives you the peace of mind you need to plan ahead for the kidding season. At the Rafter O, we’ve found that this test helps us manage our herd with confidence, and we highly recommend it to any goat breeder looking to streamline their breeding and pregnancy management process.
