Triannual evaluations are released in April, August and December. These include new phenotypic – or performance – data; therefore, both the genomic and traditional progeny evaluations are updated. All animals, genotyped or not genotyped, are shared publicly.
Between the triannual releases, genomic evaluations are not released for bulls already marketed through A.I. to provide consistency between official evaluations.
Preliminary genomic evaluations are calculated weekly – only for newly genotyped animals, or those with conflicts that were corrected. Results are processed using SNP effects from the previous official evaluation.
Weekly results help producers make immediate decisions for mating, culling and herd management. CDCB sends the preliminary evaluations to genomic nominators, dairy records processing centers and breed associations for transfer to animal owners. As they are unofficial, weekly results are not used for marketing animals or semen.
Genomic evaluations of foreign bulls are provided only to the nominator and only until 15 months of age, unless an A.I. service fee has been received by CDCB.
