Alertys pregnancy tests

Establish a protocol for reproductive efficiency with superior accuracy

  • Reduce days open, increase production, and improve herd health with accurate, fast results.
  • Our pregnancy tests are based on the detection of a panel of pregnancy-associated glycoproteins (PAGs), which are only produced in the presence of an embryo or fetus.
  • Alertys milk- and blood-based tests offer flexible testing options with results as early as 28 days postbreeding.
  • Better for cows and employees. Read how the Alertys pregnancy tests work at the McCarty Family Farm

When to test your herd
 

Initial pregnancy diagnosis
  • 28 days postbreeding for dairy cows, heifers, beef cattle, and goats
  • 29 days postbreeding for water buffalo
  • 60 days postbreeding for sheep
Throughout gestation to confirm pregnancy status
  • All ruminants
  • When you just need to know
Pregnancy confirmation prior to dry period
  • Dairy cows and heifers
 

Why use sample-based testing?

Use milk or blood samples to know if your cows or heifers are pregnant.

Alertys pregnancy tests use blood and milk samples to detect pregnancy-associated glycoproteins (PAGs), which are only produced in the presence of an embryo or fetus.

Assess overall herd health

An open pregnancy result can suggest the presence of disease.

Protect your herd from diseases shown to impact pregnancy rates, including Johne's disease, Neospora caninum, bovine viral diarrhea virus (BVDV), infectious bovine rhinotracheitis (IBR), and brucellosis.

Frequently asked questions

Milk sample collection guide

  1. Label tube prior to sampling. Include date and individual cow ID. It is essential to ensure that the correct tube is used for the correct animal. Failure to do so may result in an incorrect status being assigned to the cow. If using IDEXX Bovine Laboratory services, utilize the pre-barcoded tubes and your farm management system which will automatically keep cow ID and sample ID matched after scan.
  2. Using the wet wipes or towel, remove dirt and detritus from the teats. Ensure udder is clean and dry prior to starting sample collection.
  3. Samples may be taken from individual quarters or as a composite sample of all four quarters.
  4. Discard a few streams of milk and remove the cap from the tube or vial. Angle tube at 45º to the teat end.
  5. Fill the tube or vial three-quarters full from one or multiple quarters and replace the cap.
  6. Place samples in a refrigerator prior to shipping to the laboratory.
  7. Samples should be well-packaged and kept cool during shipping (especially if preservative has not been used).

Blood sample collection guide

  1. Label tube prior to sampling, include date and individual cow ID. It is essential to ensure that the correct tube is used for the correct animal. Failure to do so may result in an incorrect status being assigned to the cow. If using IDEXX Bovine Laboratory services, utilize the pre-barcoded tubes and your farm management system which will automatically keep cow ID and sample ID matched after scan.
  2. Restrain the cow; clean the underside of the cow’s tail with a paper towel.
  3. Lift the cow’s tail straight up and measure up about 2 inches (7.5 cm) from the base of the tail, staying within the groove between the two bony ridges. This is the collection site. 
  4. Insert the external needle into the underside of the tail, at the collection site, about 1/2 inch deep, keeping the needle perpendicular to the tail. 
    IMPORTANT: The external needle must be perpendicular to the tail. Do not angle the needle up, down, or to the side. 
  5. Push the tube in gently until the internal needle punctures the tube stopper. The vacuum will draw the blood into the tube. Note: If no blood appears, pull the external needle back slightly (without withdrawing it from the skin), and reinsert it in a different direction until you puncture the vein.
  6. When the tube is at least half full, withdraw the needle from the vein and remove the tube from the needle holder.
  7. Discard the needle and yellow/gray caps into a sharps container. The needle holder can be reused if undamaged. 
  8. Make sure the tube label is clean and dry; label the tube with the sample number and the cow ID. 

There are several options depending on which Alertys product you would like to utilize. To review where Alertys OnFarm or Rapid Visual Pregnancy products are sold, visit the distributor locator  and contact your local distributor. Learn more about IDEXX Bovine Laboratory Services to submit pregnancy or disease samples with integrated next day results. If you are unsure of which option works best for your operation, contact an IDEXX Representative  near you.

Most test kits require a sample tube for blood or milk collection. For the Alertys OnFarm Pregnancy Test, we recommend a EDTA tube for whole blood samples, which you can order through your local distributor. IDEXX Bovine Laboratory Services provides pre-barcoded blood or milk collection supplies as well as shipping materials.
