Did you miss Angus Connect?
The event covered the significant enhancements being made to the calculation of Estimated Breeding Values (EBVs) for Angus cattle in Australia and New Zealand to be released in December.
Opening the event was General Manager of Genetic Improvement, Christian Duff who announced the components of the 2022 Annual TACE Enhancements and gave a brief overview of changes
“The annual updates that are made to the TransTasman Angus Cattle Evaluation ensure that the EBVs published for Angus animals continue to be the best possible estimate of an animal’s breeding value, maximising the genetic improvement opportunities in Angus breeding programs” said Mr Duff.
Speaking at the event was Dr Steve Miller and Dr Andrew Swan, both of AGBU, and Angus Australia’s Andrew Byrne who covered the new enhancements being implemented and their impact on the TACE analysis and the resulting EBVs.
Variance Components and Other Enhancements
As the most significant of the upcoming enhancements, variance components are expected to result in some significant changes in carcase traits EBVs. Andrew Byrne described variance components as three key ‘ingredients’ – heritability, correlations and adjustment factors. During his presentation, Mr Byrne illustrated the considerable increase in data over the last decade (table 1) that has enabled the re-estimation of the variance components which were last recalibrated in 2012 from data collected in 2010. The increase in available data was most notable for carcase traits, days to calving and net feed intake – making them a better prediction of genetic merit.
