Webinar about beefxdairy breeding values

01/09/202006/03/2019 by Terhi Vahlsten

On Wednesday the 6^th of March, NAV hosted a webinar about beef x dairy breeding values, for interested beef breeders from Denmark, Finland and Sweden.
Beef x dairy breeding values can be used to select the best beef sires, for crossbreeding with dairy cattle. The webinar explained the principles behind the beefxdairy breeding values, and how to utilize them in practice.

If you are interested in learning more about beef x dairy breeding values, the webinar has been recorded and is accessible for all.

NAV Genomic Evaluation

01/09/202005/03/2019 by Terhi Vahlsten

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 Evaluation

01/09/202005/02/2019 by Terhi Vahlsten

The first NAV routine evaluation for this year took place as scheduled. The NAV Bull Search has been updated with new EBV’s and GEBV’s.

In the udder health evaluation a change in editing procedure for Swedish herds was implemented which implied that lactations were removed from herds for which veterinary reporting of diseases was incomplete. Similar editing is in place also for general health evaluation and for the other countries. The change in included information from Sweden had the effect that some bulls lost information from daughters previously included. The average change of udder health index for most bulls and cows was however minor, but some animals showed considerably larger changes.

At this evaluation, NAV published updated breeding values for beef sires based on data on beef × dairy crossbreds. This type of values were published for the first time in December 2018, but from now on they will be published in connection with the ordinary NAV evaluations four times per year. Information about BxD EBVs and publication list can be found under Beef Cattle and BeefxDairy publication.

New breeding values based on beef x dairy crossbred data

01/09/202011/12/2018 by Terhi Vahlsten

NAV has now released the first breeding values for beef sires from a new genetic evaluation that utilizes data on beef × dairy crossbreds. The use of beef semen in dairy herds has increased considerably during the past years, and these new breeding values will aid farmers in their choice of the right beef sire to use on dairy cows that are not needed to produce recruitments. Breeding values are calculated for two groups of traits: calving traits and carcass traits.

Information about the new breeding values and publication list can be found under Beef Cattle and BeefxDairy publication.
