Abstract

Genotype data on 7670 bulls from six populations (CHE, DEU-AUT, FRA, ITA, SVN, and the USA) were used to form a pooled reference population for international genomic evaluation of 34 traits (150 population-trait combinations). Genetic correlations between MACE EBV/PA, and the GEBV values were on average around 0.9 and 0.7 for the old and the young bulls, respectively. Validation of the international genomic evaluation model for 16 traits (73 population-trait combinations) was performed. All populations passed the GEBV-test for FAT, MIL, PRO, and FTL. The GEBV-test for ANG, CC2, DLO, FAN, FTP, INT, MSP, RLS, RUH, and STA indicated passing for half of the population-traits, while no population-trait passed the GEBV-test for RAN and SCS. With these results, the first phase of building an efficient international genomic evaluation system is complete, and one can move to extending the system to alternative genomic evaluation models, if one wishes so.
