Genomic relationships give improved prediction ability for a selection of traits in Norsvin Landrace and Duroc

Abstract Text:

To increase the genetic gain in our breeding program, Norsvin has implemented genomic selection for all traits in both the Landrace and Duroc breeds. Here we present some of our results leading to the decision of full implementation. In a cross validation study for different traits, with a variety of heritabilities, we observe that utilization of genomic relationship gives improved prediction ability. Precise ranking of animals is a key tool for efficient selection, and will increase the genetic progress in Norsvin’s breeding program.
