Abstract
• Leading pig breeding companies have implemented single-step evaluation for genomic selection. Overall, this increases EBV accuracies by half. • Further improvement requires focus on trait- and line-specific QTLs, exploitation of crossbred performance for non-additive genetic effects, and training for hard-to-measure traits. • The multi-breeding-company multi-line crossbred pig production structure limits very high accuracies. Increased genotyping and phenotyping will lead to improved training data and may increase accuracies by two-thirds rather than half. • Novel technologies will allow for genotyping all selection candidates, reducing the generation interval and emphasizing the need for inbreeding control, more efficient breeding structures, and higher selection intensities.
