In recent years, crossbreeding strategy has grown in dairy cattle farms at an international level. Breeders are interested in keeping crossbred cows in their herd both to combine the strengths of the pure breeds, compensate for their weaknesses and benefit from heterosis. However genetic tools are still lacking to manage these crossbred animals. In this study, we evaluate the performances of a genomic evaluation adapted for rotational crossbreeding schemes with real
data. This genomic evaluation was applied to a population that includes pure-breed animals from Holstein, Montbéliarde, and Red Danish breeds, as well as crossbreds between these three breeds. The genomic evaluation approach was based on the estimation of breed specific SNP specific according to the Breed of Origin of the Alleles.
