Reliabilities on GEBV’s are published
In November 2015 NAV starts to publish reliabilities along with the GEBV for genomically tested bulls. The estimated reliabilities (%) for candidate bulls are presented per bred for the main traits in table 1. The differences in the level of the reliabilities can to a large extend be explained by the differences in size of the reference populations for the three breeds.
