The Australian Wagyu Association (AWA) accepts the following sample types:
- Tissue Sampling Unit (TSU)
- Tail hair samples
- Semen samples
While other collection methods, such as blood tubes, can provide DNA samples, they are not preferred and should be avoided where possible.
A detailed DNA Sample Collection Guide is available to support correct collection procedures.
Tissue Sample Units (TSU)
TSUs are the preferred sampling method. Each unit must contain a tissue sample, have the red stopper securely in place and include liquid buffer. Accurate recording of the animal ID against the TSU barcode is essential; ensure you keep a copy of these at home as well.
Samples should be checked before submission. Tubes with a green stopper indicate no sample has been collected. If the buffer has evaporated and the sample is dry, it must be recollected. Leaking samples may still be acceptable if some buffer remains.
TSUs should be stored in a cool, dry place and packaged securely for postage. Durable packaging is recommended, and all shipments should be sent with tracking.
Hair Samples
Hair samples must be collected from the tail switch and include the follicles, as DNA is extracted from the follicles. Samples should be clearly labelled and recorded against the correct animal ID; ensure you keep a copy of these at home as well.
Hair must be pulled with at least 40 follicles collected to allow for potential retesting at a later date. Samples should be clean and dry (do not wash them) and avoid collecting heavily soiled samples and damp samples as they can become moldy.
Hair samples should not be collected from animals under three months of age due to insufficient follicle development. They must be submitted using the correct hair collector card and stored in a cool, dry environment prior to submission. Durable packaging is recommended, and all shipments should be sent with tracking.
Semen Samples
Semen samples must be thawed at room temperature prior to submission. Care should be taken to ensure the straw is not damaged and is not exposed to direct sunlight, which can degrade the sample.
When posting, the straw should be protected, for example:
- placing the semen straw in an old pen where the ink has been removed,
- tape the straw between two pieces of cardboard, or
- place it inside the cardboards rigid corrugated core.
As with all samples, secure packaging and tracked postage are recommended
Purchasing Collection Kits
Tissue Sampling Units (TSUs), TSU racks, TSU applicators and hair collectors are available for purchase directly through the Australian Wagyu Association. Members can contact the AWA office to place an order or make an enquiry.
Pricing for all collection kits and related materials is outlined in the AWA Fee Schedule.
