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. | Publication Type: | Conference Publication | Conference Details: | AAABG 2019: 23rd Conference of the Association for the Advancement of Animal Breeding and Genetics, Armidale, Australia, 27 October-1 November | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.23, p. 366-369 | Publisher: | Association for the Advancement of Animal Breeding and Genetics (AAABG) | Place of Publication: | Armidale, Australia | ISSN: | 1328-3227 | Fields of Research (FoR) 2008: | 070201 Animal Breeding | Fields of Research (FoR) 2020: | 300305 Animal reproduction and breeding | Socio-Economic Objective (SEO) 2008: | 830301 Beef Cattle | Socio-Economic Objective (SEO) 2020: | 100401 Beef cattle | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | http://www.aaabg.org/aaabghome/ |
