| Abstract |
Female reproduction traits influence profitability of beef enterprises, but genetic improvement has been limited. This study assessed the impact of including phenotypic reference data and genotypes on the genetic evaluations for three northern Australian beef breeds with different recording and data structures. For young (2016/17) animals, accuracy for days to calving estimated breeding value (EBV) increased 14.7% for Brahman (BB: well-recorded and genotyped), 6.2% for Santa Gertrudis (SG: limited data and small number of strategic genotypes) and 6.0% for Droughtmaster (DM: limited data and not genotyped). With these accuracy increases there is potential to increase the rates of genetic gain for key female reproduction traits.
