NAV Evaluation

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

In this evaluation single step method for conformation traits was introduced and it replaces the so called two step method. Single step uses all information from genotyped and non-genotyped animals simultaneously. In addition, the weighting of the linear traits for udder in the combined udder index have been changed for Jersey.

Calving evaluation has been upgraded to follow the defined Eurogenomic Golden standards for Jersey, RDC and Holstein
