NAV has decided to withdraw from the international beef breed genetic evaluation system, Interbeef. The decision will take effect on 4 December 2025.
The autumn 2025 evaluation has been updated in the Interbeef search and will remain available until the first evaluation of next year, which will be published at the end of February 2026. After that, the Interbeef search will be closed.
The fourth NAV routine evaluation for this year took place as scheduled. NAV Bull Search has been updated with new EBV’s and GEBV’s and NAV Beef Search is also updated with new beef x dairy breeding values.
In this evaluation, the single-step method was introduced for temperament, replacing the previous two-step method. The single-step approach uses all information from genotyped and non-genotyped animals simultaneously. Read more in the paper Improved breeding values for Temperament.
Several improvements were introduced in the general health evaluation.
NAV has also released breeding values for purebred beef bulls and cows as scheduled. Beef breeding values are updated to NAV Beef Search too.

NAV has opened a trend page for beef breeds. On the NAV Trends – Beef genetic trends for beef breeds are displayed. With trend page it is easy to display graphs that illustrate the genetic progress (the average breeding value per birth year) for sub-indices. You can choose to show the trends for different breeds and together or separately for the three Nordic countries (DFS – Denmark, Finland and Sweden).
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.
NAV has also released breeding values for purebred beef bulls and cows. Beef breeding values are updated to NAV Beef Search.
Results from two new genetic traits were added to NAV Beef Search. Protoporfyria for Limousin and Blonde d’Aquitaine and Trombopathia for Simmental. More information about genetic traits is found on NAV homepage.
