Angus HeiferSELECT Validation
An important feature of Angus HeiferSELECT is the comprehensive validation that has been undertaken to ensure it is an effective selection tool, particularly for Australian Angus in Australian production systems.
The validation includes a combination of peer reviewed journal papers and internal validation. Three peer reviewed papers, focusing on the carcase trait genetic predictions, show Angus HeiferSELECT (and the related product Angus SteerSELECT) can predict differences in phenotype and performance. The papers are:
- “Development of female fertility indicator traits for the Angus HeiferSELECT genomic tool” with conclusion: Selection based on Heifer Conception (PREG) can result in tangible gains in female fertility in Angus females in commercial enterprises through the use of Angus HeiferSELECT.

- “Development of AngusSteerSELECT: a genomic-based tool to identify performance differences of Australian Angus steers during feedlot finishing: Phase 1 validation” with conclusion: Genomic prediction equations can predict differences in carcass weight, marbling score, ossification score and carcass value in both short-fed and long-fed Australian Angus.

- “Bias, dispersion, and accuracy of genomic predictions for feedlot and carcase traits in Australian Angus steers” with conclusion: Estimates of h2 and GEBV quality metrics suggest a potential for accurate genomic selection of Australian Angus for feedlot performance and carcase traits.
