BREEDPLAN is a proven genetic evaluation system that uses pedigree, performance data and genomic information to determine a range of valuable Wagyu genetic breeding and production traits and fully supported by the Australian Wagyu Association Board for the largest genetic evaluation of Japanese Black and Red Wagyu cattle that is publicly available worldwide.

Wagyu BREEDPLAN data will be published twice a month to assist AWA members with more timely EBV data on their cattle to assist their management decisions.

Typically, the data collected includes:

  • Maternal traits such as milking, calving ease, birth weights
  • Growth weights at 200, 400 and 600 days
  • Carcase traits such as marble score, marble fineness, ribeye area, yield

To simplify reporting, BREEDPLAN produces Estimated Breeding Values (EBVs) that indicate the strength of the animal’s genetics to gain insight into the potential of animals for different production purposes which is updated each month.

The accuracy of the EBVs is dependent on the volume of the data entered and the genomic relationship with other animals.  In essence, the more data in BREEDPLAN for an animal the better its genomic relationships can be determined, the better the EBV accuracy. In addition, BreedObject $Indexes indicate the relative profitability of a sire or dam in different production systems using input from multiple EBVs.

The AWA Board has a duty to review and continuously improve Wagyu BREEDPLAN for ongoing breed development. The EBVs and Profitability Indexes are supported by AWA as representing the best scientific knowledge available at the time of publication. This is the principle method of determining the genetic merit of Wagyu animals for a range of production and profitability traits based on pedigree, recorded data on Fullblood Wagyu and genomic information.

There are four BreedObject $Indexes developed specifically for Wagyu:

  1. Wagyu Breeder Index  WBI
  2. Self-replacing Index  SRI
  3. Fullblood Terminal Index  FTI
  4. F1 Terminal Index  F1 Index

The Wagyu Breeding Guide brings together a suite of carcase EBVs to indicate the genetic merit of a wide range of Wagyu sires and dams. The EBVs will be updated on a monthly basis for member reference.

Important Notice and Disclaimer

It is very important that you appreciate when viewing the AWA database that the information contained on the AWA database, including but not limited to pedigree, DNA information, Estimated Breeding Values (EBVs) and Index values, is based on data supplied by members and/or third parties.

Whilst every effort is made to ensure the accuracy of the information reported through AWA, AWA officers and employees assume no responsibility for its content, use or interpretation. AWA disclaims all liability (including without limitation, liability in negligence) for all expenses, losses, damages and costs you may incur as a result of the use by you of the data on this AWA database and the information supplied by ABRI and AGBU being inaccurate or incomplete in any way for any reason.

Regarding EBVs and Index values, it is very important to appreciate, and you need to be aware that:

  • EBVs are derived using Wagyu Single Step BREEDPLAN technology developed independently by the Animal Genetics and Breeding Unit (AGBU), using the information contained within the AWA database.
  • AGBU is a joint venture of NSW Department of Primary Industries and the University of New England, which receives funding for this purpose from Meat and Livestock Australia Limited.
  • AWA relies solely on advice provided by AGBU and ABRI in accepting Wagyu Single Step BREEDPLAN software.
  • EBVs published in Wagyu Single Step BREEDPLAN are estimates of genetic potential of individual animals and may not reflect the raw animal phenotype.
  • EBVs can only be directly compared to other EBVs calculated in the same monthly Wagyu Group BREEDPLAN analysis.

Regarding pedigree and DNA testing results submitted to the AWA, it is very important to appreciate, and you need to be aware that:

  • Pedigree and DNA data submitted and supplied to AWA may have errors in it which cannot be detected without further DNA testing.
  • Technology may have advanced since a particular test was undertaken so that previous inaccuracies which were not detectable are now able to be detected by current testing technology.
  • AWA estimates that less than 1% of the pedigree entries, ownership or breeding details in the AWA Herdbook may have errors or which may be misleading. For this reason, users ought to consider if they need to obtain independent testing of the relevant animal (if possible) to ensure that the data is accurate.

Regarding prefectural content, it is very important to appreciate, and you need to be aware that:

  • Prefectural content is based on the estimation of prefectural origin from Japanese breeding records of 201 foundation sires and 168 foundation dams.  As genotype-based parent verification is not used in Japan, and full Japanese registration certificates are not available for all foundation animals, exact prefectural composition for these sires and dams cannot be validated.
  • The calculation of prefectural content for Australian Herdbook animals relies on the accuracy of pedigree records and DNA samples provided by AWA members.
  • The reporting of prefectural content for animals within the AWA Herdbook relies on the calculation provided by ABRI.

If you consider that you do not understand or appreciate the nature and extent of the data provided on this website or the EBVs of a particular animal, then AWA strongly recommends that you seek independent expert advice.
