How to use NAV Trends - dairy

With NAV Trends for dairy cattle you can display graphs for genetic trends for Nordic dairy cattle breeds. Here you can easily display graphs that illustrate the genetic progress (average breeding value per birth year) for NTM and other traits. You can choose to show the trends for different breeds, sex, and together or separately for the three Nordic countries (DFS – Denmark, Finland and Sweden).

NAV Trends - dairy is updated after the major NAV routine evaluations (February, May, August and November).
