The most common approach to parent verification is to take a tail hair sample and send it in a collection kit with the animal’s ear tag or ear tattoo identifier marked on the kit. These kits may be obtained from Australian Wagyu Association (AWA) (contact the AWA).
The sample is sent to an AWA approved DNA testing laboratory which must also have the DNA test results for both the animal’s sire and dam to compare against. In Australia, the approved lab is the University of Queensland (UQ) Animal Genetics Laboratory (AGL). When an animal is tested by the lab it is provided with a Case Number for the test and the lab recognises the animal by that Case Number.
The Tissue Sampling Unit or TSU from Allflex provides an alternative to pulling tail hairs to obtain a DNA sample. Guidelines for the correct use of TSUs including storage, transport and documentation to the University of Queensland Animal Genetics Laboratory are available here.
Please read these carefully if you are using the TSU’s for DNA collection.
