Polled Purebred Wagyu Fullblood have been developed through outcrossing to other breeds to introgress the dominant celtic polled allele.
The Australian Wagyu Association (AWA) has developed a genomic test to measure Japanese Black Wagyu genetics in non-pedigree crossbred animals.
This development, known as the Crossbred Wagyu Test (CWT) is intended to help the supply chain determine the potential of individual cattle to produce a ‘genuine Wagyu’ eating experience, prior to induction onto feed.
Crossbred Wagyu Tests are designed to give the level of Wagyu content and may require additional time to complete once the AWA receives the initial results from the laboratory.
All breeds of cattle, including Wagyu, are prone to undesirable genetic conditions. Fortunately, advances in molecular genetics have facilitated the development of DNA tests for their management.
Breed societies are at the forefront of the development of strategies to manage genetic conditions and seedstock members are leading the industry with their uptake of this technology.
The key inherited recessive genetic conditions in Wagyu:
- Spherocystosis,
- Chediak Higashi Syndrome,
- Claudin 16 Deficiency,
- Factor XI Deficiency and
- IARS Disorder
IARS Disorder has now been analysed for the Top 25 Foundation Sires and available to view with other genetic conditions.
Testing for the IARS Disorder is now available with the AWA. Read more
Polled Purebred Wagyu Fullblood have been developed through outcrossing to other breeds to introgress the dominant celtic polled allele.
Carrying one copy of this allele imparts the polled phenotype. However, short detached horn-like scurs can still develop.
