Genomic evaluation of BSW populations, InterGenomics: Results and Deliverables
Keywords:common genomic reference population, genomic evaluation
AbstractGenotype data on 4800 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 10 traits, amounting to a total number of 50 population-trait combinations. Genetic correlations between MACE EBV/PA, and the DGV and GEBV values were compared. Further, the gain in reliability was also examined. Correlations of EBV/PA/DGV/GEBV and reliability gain were satisfactory and in agreement with the expectations. Validation of the international genomic evaluation model for the production trait protein yield was performed. The estimated regression coefficient, although very low, were not significantly different from their expectations. Therefore, it could be concluded that pooling of the genotype data and an international genomic evaluation based on the MACE EBV were possible and countries could pass the GEBV test.
