NAV evaluation

This year’s second NAV routine evaluation took place as scheduled. The NAV Bull Search has been updated with the new EBV’s and GEBV’s. In this evaluation youngstock survival was introduced to NTM for all breeds. This had only minor effects of ranking of bulls for Holstein and Jersey. For RDC there were more effects because the weights of yield and udder were changed a bit as well.

The updated weights of NTM and correlations between NTM and sub-indices can be found under NTM and breeding values/NTM.
