The first NAV routine evaluation for this year took place as scheduled. The NAV Bull Search has been updated with the new EBV’s and GEBV’s. In this evaluation GEBV’s for young stock survival for RDC and Holstein was published for the first time as well as GEBV’s for fat and protein percent. Also the function of showing phenotypic values (breed averages and bull’s effect) has been extended with more traits.

NAV Workshop was held in Copenhagen 14th of January. Over 70 persons participated from all three countries and discussed about breeding goals and how to develop breeding. In group work participants discussed wether to include young stock survival in to NTM and about efficient cow.
Presentations of the workshop are here.
The latest NAV routine genomic evaluation took place as scheduled. NAV carried out genomic prediction for Holstein, RDC and Jersey.

Nordic trend page is updated
On the Nordic trend page genetic trends for the Nordic cattle breeds are displayed for NTM and sub-indices calculated by NAV. The page has been improved to display trends also for Claw health (in graph “Health”) and Youngstock Survival (in graph “Fertility/survival”).
Genetic trends in a population is given by the average breeding value per birth year. You can choose to show the trends for different populations, sexes, and together or separately for the three Nordic countries (DFS – Denmark, Finland and Sweden).
For both RDC and Holstein cows there has been a slight genetic improvement for both Claw health and Youngstock survival over the last seven year period. For Jersey the same can be seen for Youngstock survival whereas there is no clear trend for the Claw health index.
