How to use NAV Beef Search

How to use NAV Beef Search

NAV Beef Search consist of three parts: BeefxDairy, Interbeef and NAV Beef. At the moment only BeefxDairy is ready for use.

BeefxDairy or BxD breeding values means NAV breeding values for AI beef bulls evaluated on their crossbred offspring from Nordic dairy cows). Dairy farmers can use BxD breeding values to select beef bulls across breed for producing crossbred calves that are easily born and have a good growth and carcass quality. Crossbred calves included in the evaluation are from purebred Holstein, Jersey and RDC cows. Up to seven single BxD breeding values can be published for each bull if the publication rules are fulfilled. The single breeding values are combined with economic weights into one of two sub-indices, Birth or Growth, which are further combined into the Nordic BeefxDairy Index (NBDI). The growth index and the NBDI is available in two variants depending on production system (see more under rearing period below). BxD breeding values are updated after NAV routine evaluation (February, May, August and November).

Breeding values

All breeding values are visible in search page and in bull's own page.

Breeding value from the current evaluation is visible next to the name of the breeding value. Breeding value is expressed also graphically (except NBDI which is expressed on another scale with average of 0).

You can choose extra columns to be shown by ticking the check boxes above the list of breeding values:

  • Reliabilities
  • Previous evaluation: Breeding value from previous evaluation for trait in question.

Note!

Individual bulls might not have breeding values for every trait. This is indicated with blank on the search list and on bulls own page. The reason for missing breeding values is that the publication rules are not fulfilled.
