An animal’s breeding value is its genetic merit, half of which will be passed on to its progeny. While we will never know the exact breeding value, for performance traits it is possible to make good estimates. These are called Estimated Breeding Values (EBVs). The EBV is, therefore, the best estimate of an animal’s genetic merit for that trait. EBVs are expressed as the difference between an individual animal’s genetics and the genetic base to which the animal is compared.
An accuracy value is presented with every EBV and gives an indication of the amount of information that has been used in the calculation of that EBV. The higher the accuracy, the lower the likelihood of change in the animal’s EBV as more information is analysed for that animal or its relatives.
Accuracy Range Interpretation
o Less than 50% = Low accuracy and should be considered a preliminary estimate. The EBV could change substantially as more performance information becomes available.
o 50 – 74% = Medium accuracy, usually based on the animal’s own records and pedigree.
o 75 – 90% = Medium-high accuracy and usually includes some progeny information. Becoming a more reliable indicator of the animal’s value as a parent.
o 90% and above = High accuracy.
In addition to the EBVs for Sire, Dam and Young bulls, are three BreedObject Indexes, developed specifically for Wagyu to enable selection for profitability in Wagyu. The three $Indexes are designed to optimise profit outcomes for commercial Self-replace, Fullblood Terminal and F1 Terminal production systesm. The three indexes are:

The Wagyu Breeding Guide is a suite of carcase EBVs capable of predicting the genetic merit of a wide range of Wagyu sires and dams and BreedObject $Indexes, ranking animals based on performance and carcase data records.
It is designed to enable breeders to apply their own priorities and select appropriate sire and dam breeding for the herd. Where the seedstock genetics are unavailable, a review of pedigrees will provide an alternative selection guideline.
This document is a unique milestone for the Wagyu breed both in Australia and internationally. It has been achieved through a funding partnership with Meat & Livestock Australia and support provided by AGBU and ABRI.
Divided in two parts, the introduction outlines the genetic background of Wagyu; the second document provides the EBV summary data and will be updated on a monthly basis.
