The latest NAV routine genomic evaluation took place as scheduled. NAV carried out genomic prediction for Holstein, RDC and Jersey.
Genomic breeding values of bulls are updated to NAV Bull Search after each evaluation.

At the same time as including youngstock survival in NTM, RDC is changing the weights for some other indices in NTM. Weight on yield and udder conformation is increased slightly. This is done to secure that genetic progress for these traits are maintained when introducing youngstock survival in NTM.
The change has only limited effect on ranking of bulls.
All the current weights for different sub-indices in NTM and the correlations between NTM and sub-indices can be found on NAV web page (www.nordicebv.info) under NTM and breeding values/NTM.
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.

NAV has launched a new NAV Interbull Search page for bulls having Interbull evaluation on Nordic scale. With this page it is easy to find the best bulls around the world.
NAV Interbull Search has almost all the same features as NAV Bull Search and it is very easy to use. Bulls can be found according to breed, birth country or birth year. It is possible to sort bulls by different breeding values. More information is found on the bull’s own page.
NAV Interbull Search is updated after each Interbull evaluation, three times a year. For RDC and Jersey there is Interbull breeding values based only on progeny information (EBV) but for Holstein there is also genomic breeding values available (GEBV).
Compared to previously, NTM for genomically tested foreign bulls based on Interbull GEBVs will no longer be displayed on the page. For daughter proven bulls, both domestic and foreign, the publication is unchanged and their NTM is displayed and based on Interbull EBVs.
NAV Interbull search can also be reached directly from NAV start page.
