New Saved feed index

by

In February 2025 evaluation, a new Saved feed index was introduced. The new index is based on dry matter intake (DMI), production (ECM) and weight change. The interpretation of the index remains the same: higher index values indicate lower feed intake. One index corresponds to a reduction of 15-20 kg in dry matter intake per lactation. There is a low correlation between the old and the new index for saved feed which means a large reranking between animals for the saved feed index. Since Saved feed is included in NTM there will also be a minor effect on NTM.

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.
