A multifaceted approach to the use of genomic selection in new traits
As the first phase of the genomic use in livestock comes to a closure with the routine application of genomic selection schemes in most species of commercial interest, it is worth noting that a large part of the efforts in this phase have been dedicated to the translation of traditional programs with the aid of genomics. For traits that do not benefit from large reference populations a combinations of approaches might be used to obtain short to mid-term advances. The use of voluntarily collected data in commercial populations can be a self-contained method to increase the number of traits and individuals available for selection in a cost-effective way. Concurrently the use of ancillary biological information can help improving the correlation between markers and QTL, thus reducing the number of individuals/markers needed to effectively selecting for complex low heritability traits.
