New Accuracy Calculation Software for Single-Step BREEDPLAN Analyses

Implementation December 2022 – January 2023

Dec 2022

As the volume and density of genomic information used in BREEDPLAN evaluations continues to grow, it has highlighted the need for a more efficient way to better account for SNP effects in the calculation of EBV accuracy. An advanced algorithm for accuracy calculations has now been developed. This is scheduled to be implemented over the period of December 2022 and January 2023 for all clients (as shown below) currently using the Single-Step BREEDPLAN model:


Breed Societies

Angus Single-Step BREEDPLAN

Angus Australia & New Zealand Angus Association

Brahman Single-Step BREEDPLAN

Australian Brahman Breeders’ Association

Hereford Single-Step BREEDPLAN

Herefords Australia, New Zealand Hereford Association & Hereford Cattle Breeders Society of Namibia

Santa Gertrudis Single-Step BREEDPLAN

Santa Gertrudis Breeders Association

Wagyu Single-Step BREEDPLAN

Australian Wagyu Association

While changes in accuracy might be observed for certain traits and for certain individual animals, this enhancement to the analytical software will ensure that BREEDPLAN continues to make the best use all sources of information involved in the calculation of accuracy.
