The first genetic evaluation to include genomically-enhanced EPDs is slated for this month.
- Traits evaluated include Birth Weight, Weaning Weight, Yearling Weight and Carcass Weight
- For the March evaluation, EPDs will be calculated using the usual software, then genomic information is incorporated into the evaluation after it is run.
- Known as “two-step” or “blended” genomically-enhanced EPDs.
- Breeds that currently have genomically enhanced EPDs are using this method.
- The blended method impacts the animals who have been DNA tested.
- The EPDs for these traits WILL be comparable to other IGS breeds, as they were calculated through the same system, then the Shorthorn genomic information was added.
- In the future, we will be moving to newer technology (single step method)
- BOLT software
- Will combine pedigree, phenotypic data, and genomic information into the genetic evaluation simultaneously
- Single step genomically enhanced EPDs not only impact the animal that has been DNA tested, but also related animals.
- The goal at IGS is to introduce single-step genomically enhanced EPDs for growth traits first, followed by carcass traits and maternal traits.
- The new Stayability EPD will be calculated using single-step methods.
