Are PACE young sires being selected differently?
We have also incorporated the use of genomic scanning for acquiring young bulls for our PACE program. Meaning we are selecting sires with the highest quality genomic proofs while keeping a diversifi ed pedigree. With the help of genomic testing we will continue to be selective when we bring in sires and it is another tool that we use in sourcing the best genetics of the future. Overall, the PACE herds will have the advantage of much better genetics due to removal of bottom end bulls prior to sampling.
What is the difference between PACE young sires and GeneFORCE™ sires?
GeneFORCE is a group of genomically superior young sires. The GeneFORCE sires are an elite group of young sires that have already been sampled through our PACE program. Producers can use GeneFORCE sires with confidence. The young sires’ information now includes a combination of genomic and traditional summary data. This increases the reliability of the young sires information and gives a more accurate estimation of each sire’s true transmitting ability.
What is the approximate reliability for bulls with a genomic only proof?
Expect most young Holstein bulls with genomic proofs to range between 62 and 72 percent reliability for all traits. Jersey young bulls will be a bit lower in reliability.
Are GeneFORCE bulls being used as sires of sons?
Yes, Accelerated Genetics is currently using GeneFORCE sires as sires of sons for a small percentage of our matings. Our sire selection program incorporates many traits combined together in a customized selection index which includes production, type and management traits.
Where does Accelerated Genetics conduct their genomic scanning?
All of our sires are genomically scanned through Genetic Visions, Inc., Accelerated Genetics research subsidiary, located in Middleton, Wis. Once the genomic scan data is complete, the raw data is forwarded to the USDA where they transform the information into genotypes using their reference populations. The USDA then uses a subset of genotypes to calculate a Genomic PTA for each of the 29 traits presently listed. Genetic Visions, Inc. has been leading the industry in bovine research since 1988. Genetic Visions recently achieved Illumina’s CSPro Certification for Infinium Whole-Genome Genotyping. While this certification is not required for a lab to conduct genomic scans, the certification demonstrates that additional steps are in place to maintain quality assurances. At present there are three commercial labs in the United States conducting bovine genomic scans.
