NAV Evaluation

by

The fourth NAV routine evaluation this year took place as scheduled. NAV Bull Search has been updated with the new EBV’s and GEBV’s.

In this evaluation single step method was introduced for fertility and it replaces the so called two step method. Single step uses all information from genotyped and non-genotyped animals simultaneously.
