Use Young Bulls More

Genomic Validation Tests Predict 2010 daughter data using 2006 PA or genomic PTA DYD2010 = apa + bpa PA2006 + e DYD2010 = apta + bpta PTA2006 + e Statistics from Jorjani, 2010 Interbull Genomics Workshop Foreign average includes DEU, FRA, NLD, DFS, JPN, POL, NZL, and CAN FRA not latest data (10,000 bulls)

Regressions and Gains in R2 When predicting last 4 years of data Gain in R2 Trait USA Foreign Yield .91 .85 24 22 SCS .80 .97 15 23 Longevity 1.10 .98 8 Final score .89 .90 Udd depth 1.01 30 31 Stature 26

Validation Results EuroGenomics reliabilities about 5% higher than in North America 10% REL gain from exchange Similar regressions, slightly < 1.0 Validation expects regressions < 1 with selective genotyping of bulls Means of genotyped vs. nongenotyped Most countries genotyped all recent bulls
