Beef Evaluations

NAV Beef evaluation

by

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

In this evaluation genomic breeding values for weight/growth and carcass traits were published for the five main breeds (Aberdeen Angus, Charolais, Hereford, Limousin, Simmental). For other traits and breeds, breeding values are based on phenotypic information.

In NAV Beef Search it is possible to search after genomic proven animals, and the genomic status is also shown on animal’s own page whether the animal is genomic proven or not.

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.
