There are 2 simple ways to submit a sample for genotyping:
Tissue Sampling Unit
- To collect a tissue sample, you will require an Allflex tissue applicator and a tissue sampling unit or TSU.
- Using the applicator and TSU, you will collect sample directly from the ear.
- Each TSU contains stabilization and transportation medium.
- TSU’s can be used to collect tissue samples for all animals regardless of age.

- Comb or brush the tail area at the upper part of the switch to remove any
foreign material. Dirty, contaminated samples will not be processed
- If necessary, wash and rinse area with water and allow time to dry before
- Use withers, topline, or ears as alternatives
- Collect 35 to 50 hair roots/follicles to ensure better test results

- Blood is generally used for Freemartin testing
- It is not recommended that blood be drawn from an animal that is under 6
weeks of age
- Use a tube with a purple or green stopper
- Bleed until tube is about 3/4 full
- Keep sample from heating or freezing
- Not available for purchase
- This testing option is generally provided by AI units
- Clearly mark the tube with name and registration number of sampled bull
- Not available for purchase

Why Use Various Genotyping Options?
- To increase reliability and accuracy of genetic evaluations
- To select the 'right' heifers at an earlier age
- To enable faster genetic progress in your herd
- To optimize mating of heifers
- To help make more informed marketing and management decisions
- To recover return on investment for the cost of rearing heifers
- To correct existing parent error
- To be informed of non-observable genetic conditions (Beta-Casein, Cholesterol Deficiency etc.)

| Genetic Recessive & Coat Colour Transmitting Codes
|| Genetic Recessive Descriptions
|BL - BLAD
||Deficiency of a normally occurring protein needed for white blood
cells or leukocytes, which are body’s infection fighters.
|CC - Coat Colour
||To identify colours & colour transmission.
|BY - Brachyspina
|| Causes abortions, stillborn, shortened spinal cord, long legs and
| CV - CVM
|| Causes abortions, stillborn, and early embryonic losses.
| PL - Polled
|| Polled in Holstein refers to the absence of horns and scurs—animals
born naturally hornless. The polled characteristic in cattle is
inherited as a simple, dominant gene. Therefore, horns result from two
copies of the recessive gene at that location on the chromosome.
| DP - DUMPS
|| One of many enzymes contributing to normal metabolic processes.
| Beta Casein A2
|| A1 A2 Milk protein.
||Included (or $15 standalone with no SNP evaluation)
| Standardized test for parentage verification to support Herd Book
integrity. Request can be upgraded to LD, LD Plus or MD test. MS may
be required to support exchange of data internationally, related to
export of semen embryos and live animals.
Note: Parentage verification can be conducted using LD, LD Plus and
