NAV Trends Beef is open!

by

NAV has opened a trend page for beef breeds. On the NAV Trends – Beef genetic trends for beef breeds are displayed. With trend page it is easy to display graphs that illustrate the genetic progress (the average breeding value per birth year) for sub-indices. You can choose to show the trends for different breeds and together or separately for the three Nordic countries (DFS – Denmark, Finland and Sweden).

NAV Genomic Evaluation and NAV Beef Evaluation

by

The latest NAV routine genomic evaluation took place as scheduled. NAV carried out genomic prediction for Holstein, RDC and Jersey. Genomic breeding values of bulls are updated to NAV Bull Search after each evaluation.

NAV has also released breeding values for purebred beef bulls and cows. Beef breeding values are updated to NAV Beef Search.

Results from two new genetic traits were added to NAV Beef Search. Protoporfyria for Limousin and Blonde d’Aquitaine and Trombopathia for Simmental. More information about genetic traits is found on NAV homepage.

Subindices for new beef breeds

by

In November 2023 nine new beef breeds were included into NAV purebred beef evaluation. First, only breeding values for single traits were published but now NAV has also published subindices for new beef breeds. Seven subindices include same traits for all breeds, but weight factors are breed specific.

Read more about the subindices from NAV newsletter and from a paper New indexes for nine beef breeds.

More information about the beef breeding values and publication can be found at NAV homepage under Beef publication.
