New on-line monthly updates of Wagyu EBVs

Wagyu-conferenceThe 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 breed values from performance and carcase data. Wagyu breeding guide summary_cover

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 are targeted specifically to a defined production and market system, whether it is for a self-replacing herd, Fullblood terminal or F1 terminal herd.

Based on Wagyu BREEDPLAN data, the most accurate assessment outside Japan, the Wagyu Breeding Guide draws on analysis of more than 84,000 dams and 10,000 Fullblood sires and more than 24,000 Fullblood records for animal birth, weaning and 400-Day weights. Fullblood carcase data includes 7,000 carcase weights, 6,700 Aus-Meat assessments, plus 3,000 Digital Reflective Camera Assessments for marbling percentage and fineness. The use of 50K SNP genomic profiles, introduced April 2018, has significantly improved EBV accuracy.

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

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.

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.

To be included in the Wagyu Breeding Guide:

Sires

  • More than 10 progeny registered
  • Registered progeny born within the past three years
  • Minimum accuracy of 80% for 200-Day, 400-Day or 600-Day weight EBVs

Dams

  • More than three progeny registered
  • Registered progeny born within the past three years
  • Minimum accuracy of 80% for 200-Day, 400-Day or 600-Day weight EBVs

Young Bulls

  • At least five years old
  • EBVs better than breed average for 200-Day, 400-Day or 600-Day weight
  • Minimum accuracy of 50% for 200-Day, 400-Day or 600-Day weight EBVs
