Understanding Myostatin E226X

Recently, a copy of a Myostatin Gene mutation, known as Myostatin E226X, was described within the Shorthorn population in Australia. The Myostatin Gene is essential for the proper regulation of skeletal muscle mass. Mutations to the Myostatin gene make the gene less active or inactive, resulting in variations to normal phenotypes which can include muscular hypertrophy or double muscling.

How to submit DNA tests

DNA typing of cattle represents a significant improvement in herd recording technology.

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 $110 inc. GST and also provide parent verification and poll testing included in the price.

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 $29.70 inc. GST providing the sire and dam have a SNP panel recorded. Please allow $29.70 for each of the sire and dam if they also require a SNP test analysed for parent verification.

Collecting DNA samples is a simple process. Allflex TSU samples are one preferred for submission of DNA samples, however tail follicle kits can also be used and for sires a correctly marked semen straw can also be used.

Tail follicles kits for submission of samples for testing may be obtained by request from the Shorthorn Beef Office and are the most common form of DNA sample submissions.

It is recommended that all Sires and Donor Dams are DNA profiled prior to joining to ensure that there are no concerns later on.

TSU Sample Kits

TSU sample kits offer the best solution for collecting and submitting DNA samples. Samples can be collected with a minimum of animal restraint and a minimum of animal discomfort.

TSU kits collect a small sample from the ear which is automatically sealed in a small vial and in a specialised preservative. This means that there is no risk of contamination and reduces the possibility of retesting being required. Tissue samples contain a large quantity of high quality DNA yielding excellent lab results.

The TSU vial is fully sealed in the applicator with both a 2D barcode and an ID panel. The TSU sample can be paired to matching NLIS and management tags, maintaining the maximum integrity for animal identification and sampling records.

TSU samples can not be stored for later use, should further DNA testing be required, so there is a fee for extracting full DNA from each sample.

TSU Kits and applicators can be ordered from Allflex by Freecall 1300 138 247. Or download the Allflex TSU brochure here TSU Brochure 2017.

IMG_3882Collecting Tail Follicles

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 between 4 to 6 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.

There are some limitations regarding submitting DNA samples by semen straw. Firstly, please make sure the straw is thawed before you post it as the sample may develop mould in the post otherwise. Semen samples can not be stored for use later if further DNA tests are required, so if the best way is to send a semen sample, there is a fee for extraction of full DNA from the sample for storage. Ideally, semen straws should be protected in the post by either taping them between two sheets of cardboard, wrapping them in tissue paper or simply removing the insert from a cheap biro and replacing it with the semen straw.

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. 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 all Sires prior to joining to avoid any concerns later on.
