What is bioPRYN?

BioPRYN is a preferred means of pregnancy detection in cattle.
  • Accurate results 28 days post-breeding for cattle or 40 days post breeding for bison and 73 days post calving. 30 days post-breeding for goats and sheep.
  • Convenient and versatile, allowing you to schedule pregnancy testing when it fits for you.
  • Cost-effective and easier way to check for pregnancy than ultrasound or rectal palpation.
  • Non-invasive and embryo safe, reducing the risk of damaging a pregnancy and causing embryo loss.

Why BioPRYN?

  • Provides flexibility in scheduling pregnancy testing dates
  • Fits within synchronized breeding protocol
  • Accurate results 28 days post-breeding
  • Safe for embryo

Over 97% Accurate PREGNANT COWS:  95% correctly designated.  False positive tests occur due to early embryonic death. Even though the embryo has died, some
residual pregnancy protein may still be in the cow’s system. OPEN COWS:  99% - 100% correct when a cow is designated as open.  Extremely accurate detection of
non-pregnant, open cows. Re-enroll these cows in synchronization programs with confidence!   

postal shipping instructions:

  • 1) Bundle tubes together in groups of 1-10 tubes with a rubber band.
  • 2) Place inside a leak proof zipper bag or baggie. Do NOT ship samples with ice. In hot weather please send blood samples with frozen ice pack in separate baggie. Please do not tape around samples. Frozen ear notches for BVD should always be sent with an ice pack.
  • 3) Wrap the bundle with absorbent paper towels or newspaper (enough to absorb all fluid if all tubes break). Seal the box with tape securely.
  • 4) Write biohazard on the plastic bag. DO NOT WRITE “BIOHAZARD” ON THE OUTSIDE OF THE BOX!
    This would cause delays in shipping.
  • 5) Pack bubble wrap or newspapers around the bag inside the box (we do not suggest using padded envelopes because they cause the tubes to break).
  • 6) If you have packaged using this procedure, write the following on the outside of the box: Exempt Animal Specimen
  • We suggest asking your local Post Office about the Flat Rate Boxes.  This may save money on shipping costs

Is BVD virus a problem for your cow herd?

Bovine Viral Diarrhea Virus (BVD) is one of the most costly diseases in cattle worldwide, with a variety of syndromes.  What’s worst, the virus is very common, very contagious, and very few herds have not been exposed to the virus at one time or another.  On the plus side, the infection is usually mild, with high morbidity (lots of cattle get infected) but low mortality (not many deaths due to BVD virus).

Cow-calf operations are especially at risk from BVD virus because if cows are infected during pregnancy, embryonic death or abortion, birth of undersized, weak calves, or calves with congenital  (persistent) infections can result.

Cows that are infected with a case of BVD seldom appear sick.  While clinically unapparent in the dam, the effect on the fetus the cow is carrying varies with the strain of the virus and the age of the fetus.  Abortion or mummification, may occur following infection in early to mid-gestation.  Even worse, apparently normal calves may be born that are congenitally, or persistently, infected with the BVD virus.  The calves are dangerous and continuous sources of BVD virus for the entire herd every day of their life. Older fetuses with developed immune systems that are exposed to the virus in late gestation (>150 days) may respond the infection and produce antibodies that defeat the infection with no long term adverse effects.

Neospora Infection Testing

download submission form

$4.50/ sample. Test is run off whole blood or serum.

Neosporosis is a fairly recently recognized coccidian parasite that is a major cause of abortion in cattle.  One of the biggest problems with Neospora is that apparently healthy cows may have a chronic, lifelong infection, and this infection makes the cow several times more likely to abort a pregnancy.  Just as important, cows that are infected will very likely pass the infection on to their calves, and the calves will be infected from birth.

While not all cows chronically infected with Neosporosis will abort, they are, according to research, at a 3 to 7 times greater risk of abortion than Neospora negative, non-infected herdmates.  Those Neospora positive cows that do not abort have a high probability (80 to 90%) of producing calves that are congenitally infected with Neospora.

Johne's Disease Testing

download submission form

(Pronounced “Yo-nees”) $4.50/ sample. Test is ran off of whole blood or serum.

Johne’s disease is caused by Mycobacterium paratuberculosis, a hardy bacterium that embeds itself in the wall of the lower part of the small intestine known as the ileum. As an immune response, infected tissues attempt to regenerate healthy tissue which leads to visible thickening of the intestines. This prevents nutrient absorption, resulting in weight loss. Late in the infection, antibody production by the animal can be found in serum of animals and is an indicator that clinical signs of disease and death from the infection will soon follow.

BLV - Bovine Leukosis VirusTesting

download submission form

$6.50 for less than 10. $4.50 for 10 or more. Test is ran off of whole blood or serum.

Bovine leukosis is a cancerous disease caused by Bovine Leukosis Virus (BLV). This is a retrovirus that infects beef and dairy cattle, targeting lymphocytes, a type of white blood cell. These cells are part of the immune system. Infection with the virus most often does not cause any clinical signs, however, about 30% of the infected animals develop a lymphocytosis, or abnormal increase in lymphocytes in the blood. This is sometimes referred to as “leukemia” although it is different from most forms of human leukemia.

How To Tail Bleed Cattle

Watch Tail Bleeding Video

  • 1a) If using a vacutainer and a double ended bleeding needle, screw the bleeding needle onto a needle holder. Insert the vacutainer tube into the other end of the needle
    holder until the stopper on the tube touches the needle in the holder body. Do NOT puncture the stopper (or you will lose the tube vacuum and the tube will be no good). Hold
    the assembly in one hand. (Note that the needle holder is re-usable, the needle must only be used once.)
  • 1b) If using a needle and syringe, secure the needle on the syringe, and hold in one hand (Do not reuse).
  • 2) Lift the cow’s tail with your other hand.
  • 3) Insert the needle about ½ to ¾ inch deep and perpendicular to the tail at the underside of the tail, at the midline, and 2 or 3 inches from the base of the tail. When you lift the tail, you can feel “soft” areas directly under tail, above the rectum. This is the target you seek to penetrate with the needle.
  • 4a) If using a vacutainer tube, direct the needle into the tail vein until blood appears at the junction of the needle and tube stopper. When the blood appears, push the tube onto the needle. Blood will rapidly start to fill the tube. If it does not, redirect the needle to find the vein. BE SURE TO KEEP THE TIP OF THE NEEDLE UNDER THE SKIN or THE VACUUM WILL BE LOST. If the vacuum is lost prior to the blood tube filling, the tube must be replaced. For this reason, some people prefer to use a needle and syringe to draw blood.
  • 4b) If using a needle and syringe, apply slight traction to the plunger. Blood will start to fill the body of the syringe if the needle is in the right spot. If not, pull back on the needle and redirect until blood appears freely.
  • 5) Collect 2cc or more of whole blood using either a red top vacutainer tube and bleeding assembly, or a needle and syringe. If using a needle and syringe, immediately empty the syringe into a red top vacutainer tube. (DO NOT SEND BLOOD IN SYRINGES!)
  • 6) Label the sample tube with the animal’s ID using a permanent marker on the vial label. Please label the tubes carefully and permanently to assist the lab in providing accurate results.
  • 7) Place the tubes in a refrigerator until shipment.
  • 8) Completely fill out the BioPRYN® Pregnancy Test Submission Form. Be certain the total number of samples sent is correct and they are labeled clearly. (Be sure #1 cow in #2 tube can’t be confused with #1 tube holding #2 cow sample.)
  • 9) Return samples to the lab in a box. Refer to Postal Shipping Procedures.

Instructions for Hair Sample Collection from Cattle
  • Collect hair samples from the end of the tail (the tail switch).
  • Remove any manure or grass/straw from the tail. Sometimes washing of the tail will be necessary.
  • Grasp a clump of hair (about as thick as a ball point pen) with either your hand or pliers. Pull the hair samples out with a sudden movement so as to pull the hair with the follicle from the tissue. The hair follicles embedded in the tissue are needed for testing, not the actual hair.
  • Make sure that you have 30-40 follicles. If you do not see 30-40, pull more hair.
  • Place hair in a hair card (purchased at SEK Genetics).
  • Hair samples not submitted in a hair card, will not be ran.
