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.
