Several initiatives have either been completed or are nearing completion with regards to the analysis of genomic information within the Angus TACE genetic evaluation.
New trait indicators are now available to assist with the identification of whether animals’ have had genomic information included in the calculation of their Angus TACE EBVs.
Animals for which genomic information is included in Angus TACE will have one of the following trait indicators, subject to the genomic information that is analysed and the analytical methodology utilised.
Genomic information is not currently included in the calculation of EBVs for docility and the structural soundness traits for any animals.
The new genomic trait indicators can be viewed by searching for an animal in the Angus Database Search facility, and then selecting the EBVs tab. The trait indicators are displayed within the traits observed section, which is towards the bottom of the EBV table.
Additionally, the number of progeny from a particular sire or dam who have genomic information analysed in the main single step component of Angus TACE are now also displayed in the traits observed section within the Angus Database Search.
In association with the implementation of the new single step analytical software into the December 2017 Angus TACE genetic evaluation, a range of comprehensive quality assurance checks are now applied before genomic information is included into the analysis.
The quality assurance measures not only review the quality of the genotypes for measures such as call rate and the level of heterozygosity, but identify any discrepancies between the genomic information and the information recorded on the Angus Australia database. For example, discrepancies in the pedigree, gender and breed that is recorded for the animal.
Angus Australia’s software development team is now actively working on the development of herd reports for each member of Angus Australia that is enrolled in Angus TACE that identify any genomic information that has failed the quality assurance checks and been excluded from the Angus TACE analysis.
Notification will be sent to Angus Australia members once the new genomic exclusion reports are available.
