Abstract

The European Brown Swiss Federation, in collaboration with Interbull, founded in 2009 and managed Intergenomics, an international project to perform genomic evaluations of sires based on a joint analysis of all the Brown Swiss genotypes collected in the participating countries. In this paper, we describe how this project and the genotypes are used in France. After a long list of quality controls on animals and genotypes, the French routine genomic evaluation based on a Marker-Assisted BLUP (MA-BLUP) is carried out. Compared to the pedigree-based BLUP, genomic selection allows a gain in correlation between observed and predicted sire performance between 5.2 and 26.8%. The French genomic evaluation is now performed on 29 traits and has been official in the French Brown Swiss breed since June 2014.
