NAV Evaluation

by

The first NAV routine evaluation this year took place as scheduled. The NAV Bull Search has been updated with the new EBV’s and GEBV’s. NAV Beef Search is also updated with new beef x dairy breeding values.

In the dairy cattle evaluation new saved feed index was introduced. While the name and the interpretation of the index remain unchanged —higher values still indicate lower feed consumption—the index has undergone significant changes. These changes have affected the correlation between NTM and the saved feed index across all breeds. Additionally, the weight of saved feed in NTM has been adjusted for Holstein.
