How to submit DNA tests
It is requirement of Shorthorn Beef that any Sire of calves to be registered with Shorthorn Beef, have a DNA sample submitted to Shorthorn Beef before the resulting calves may be registered.
It is also a requirement of Shorthorn Beef that any Donor Dam of Embryo Transfer calves to be registered with Shorthorn Beef, have a DNA sample submitted to Shorthorn Beef before the resulting Embryo Transfer calves may be registered.
DNA Profile Tests cost $33 inc. GST
Paternity and Maternity tests may also be performed, allowing breeders to identify the pedigree of calves when they may be unsure. Provided the potential Sires and Dams are DNA profiled, simply supply the list of potential parents to Shorthorn Beef and a Parent Verification Test can be done.
Parent Verification Tests cost $44 inc. GST
Collecting DNA samples is a simple process.
For Sires, either a thawed semen straw or tail follicles are sufficient. For Donor Dams, tail follicles are all that is required.
Tail follicles kits for submission of samples for testing may be obtained by request from the Shorthorn Beef Office.
It is recommended that all Sires and Donor Dams are DNA profiled prior to joining to ensure that there are no concerns later on.
Tail hair follicle sample kits have a cardboard back and a clear, sticky plastic front.
The tail hair follicles (ie the hair roots) are the required section of the hair samples for testing. Usually the follicles are seen as the white tips at the end of the hair samples. Generally, about 20 follicles is sufficient for a sample. Please ensure, where possible, that samples are taken from the brush of the tail.
Tail hair samples should be cleaned and dried before submission, as mould may develop in transit if the samples are still wet and dirty.
Simply peel back the sticky clear section of the sample kit and place the follicles on the cardboard and then lay the sticky plastic back over. Trim the other end of the hair sample at this point.
Record the animals ident on the sample card and post the samples back to the Shorthorn Beef Office. It takes around 4 weeks for DNA to be tested and the results will be mailed back to you directly.
Semen Straw Samples
Sending a semen straw is another easy way of collecting DNA on sires.
Simply thaw a straw of semen or retain a used straw from the AI program, wrap it up in tissue paper or similar, and post it to the Shorthorn Beef Office, with the animal ident clearly marked for each straw.
Please make sure the straw is thawed before you post it.
If progeny registrations are rejected because the Sire was not DNA profiled, simply have the Sire profiled and inform the Shorthorn Beef Office once you obtain your DNA profile in the mail. Unless the Office is informed of the Sires DNA profile status, they will not be able to proceed with registrations.
It is possible to receive an exemption for Sires that have died unexpectantly without a DNA profile, however exemptions will only apply for that year. It is recommended that DNA samples are taken from Sires prior to joining to avoid any concerns later on.
