Brown Swiss genomic evaluation

In the framework of the Intergenomics project initiated by the European Brown Swiss Federation, a common reference population for genomic evaluation has been created to enable participating countries to estimate SNP effects more accurately. Genomic data of 3392 Brown Swiss bulls from 7 countries were evaluated for protein yield, somatic cell score and non-return rate based on GBLUP. Accuracy of GEBVs of bulls with at least 10 daughters for protein and somatic cell score were larger by about 5% than the conventional proofs, for non-return rate the difference was about 13%. For young bulls genomic reliabilities were about 2.5 times larger than the respective parent averages. Correlations between conventional proofs, DGVs and GEBVs were close to 1.
