Abstract

The first multi-country multi-trait single-step GBLUP (ssGBLUP) BREEDPLAN analysis was released for the Hereford breed in October 2017, combining the pedigree, performance and genomic data from Australia, New Zealand and Namibia. Nearly 18 months later, Hereford breeders have embraced genotyping with a 3.8-fold increase in number of animals genotyped. The inclusion of genomic information has influenced the Estimated Breeding Values (EBVs), although this varies by trait and animal. Similarly, exclusion of hard-to-measure phenotypes from the analysis confirms the importance of recording phenotypes for the estimation of accurate EBVs, even when utilising ssGBLUP. The collection of both genotypes and phenotypes, particularly for hard-to-measure traits, remains vital in allowing beef producers to best utilise ssGBLUP.
