NAV Beef Search is open!

NAV has launched a new NAV Beef Search for beef bulls. With NAV Beef Search it is possible to search for beef bulls that have either pure beef progeny or crossbred progeny. In the beginning NAV Beef Search will only include beefxdairy search which includes the results of NAV beefxdairy evaluation.

NAV Beef Search has many of the same features as NAV Bull Search and NAV Interbull Search and it is very easy to use.  The search page contains all publishable breeding values and other relevant information for the AI beef bulls included in the evaluation. The user have to select the appropriate rearing period (short or long) to get the result. Bulls can be found according to the breed, birth country, birth year or by name. It is possible to sort bulls by different breeding values. More information is found on the bull’s own page.

NAV beefxdairy breeding values are published four times a year in connection to NAV evaluations for dairy (February, May, August and November).

The results of Interbeef and NAV Beef evaluations will be implemented to NAV Beef Search later.

NAV Beef Search can also be reached directly from NAV start page.

NAV introduces an index for Saved feed

At the genetic evaluation in August 2019, NAV will for the first time publish breeding values related to feed efficiency. There will be a new sub-index called Saved feed, which is an index that in the future will include two breeding values, maintenance efficiency and metabolic efficiency. In August however, only maintenance efficiency goes into the index, but metabolic efficiency will follow as soon as development work is finalized. Saved feed gives a dairy farmer the opportunity to breed for cows that are more feed efficient.
