Wagyu Breeding Guide

The Australian Wagyu Association is now providing online monthly updates of the Wagyu Breeding Guide EBV Tables for Sires and Dams.

Designed to enable breeders to apply their own priorities and selection criteria to suit their business operations, the Breeding Guide EBV Tables pull together a range of estimated breeding values from performance and carcase data.

Breeding Guide Introduction

Included in the Tables are EBVs on calving, growth and maternal, and carcase traits. The recently developed BreedObject $Indexes, specifically for Wagyu, are also provided. These $Indexes use genetic information from multiple EBVs and are targeted specifically to estimate profitability of a sire or dam for a Self-replacing herd, Fullblood terminal or F1 terminal herd.

The Wagyu BREEDPLAN analysis provides the most thorough and accurate assessment of Fullblood Wagyu genetics available outside Japan. The analysis includes more than 120,000 dams and 14,000 sires. In addition, there are 38,500 animals with birth weights, 44,500 with weaning (200 Day) weights and 35,000 with 400 Day weights. Fullblood carcase data includes records from 13,000 carcases including AUS-Meat and MIJ marble scores, camera marbling percent and camera fineness index measures. (Data as at 30 June 2021).

First published in 2015, the Wagyu Breeding Guide simplified the selection process for breeders, by providing a list of bulls and females within the Australian Wagyu Association database with substantial performance and carcase data recorded.

Provided in two parts, the Wagyu Breeding Guide Introduction gives the background to the Wagyu industry including its rich Japanese prefectural heritage, while the Summary Tables provide the data for Sires and Dams. The Young Sires table lists bulls with more than 50% accuracy, enabling breeders to select for accelerated genetic gain.

High performing, well-described Wagyu genetics are needed for Fullblood and Crossbred Wagyu supply chains, and with parent-verified seedstock registrations and numbers of genomic profiles recorded by members increasing each year, the accuracy of EBVs will continue to improve. As a result, publishing the data will occur on a monthly basis following each Group BREEDPLAN run.

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 pubished in Wagyu Single-Step BREEDPLAN are estimates of genetic potential of individual animals and may not reflect the raw animal phenotype.
  • EBVs can only by directly compared to other EBVs calculated in the same monthly Wagyu Group BREEDPLAN run.

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 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.

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.

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.
