12 S-1008 meeting, 2006 (12) P.M. VanRaden 2006 Possible Economic Measures  Lifetime Profit or ANRI-OC  Discounted net present value  Annualized profit / annualized cost  Return on investment  Others?

17 S-1008 meeting, 2006 (17) P.M. VanRaden 2006 Genomic EBVs for Real Bulls  USDA-BFGL study with industry funding using 60,000 SNPs  Genotype ~2000 proven bulls  Predict ~400 bulls sampled later  Reliability = 71% vs 36% from PA  Higher if LD & major loci assumed

18 S-1008 meeting, 2006 (18) P.M. VanRaden 2006 Conclusions  Corr (USA, foreign stillbirth) ~.70  All-breed genetic trends seem reasonable  Several economic goals are possible  Dense maps will change selection
