Youngstock survival included in NBDI

by

The fourth NAV routine evaluation of beefxdairy breeding values took place as scheduled and NAV Beef Search is updated with new beefxdairy indices.

In this evaluation youngstock survival was included in Nordic BeefxDairy index (NBDI). At the same time the economical weights of all NBDI traits were updated. These changes cause significant reranking between the bulls and for many of the bulls the NBDI value changes several index points.

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 Evaluation

by

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

In this evaluation single step method was introduced for fertility and it replaces the so called two step method. Single step uses all information from genotyped and non-genotyped animals simultaneously.

In the calculation of conformation indices, the breed averages have been updated for all breeds, and that especially affects the frame index for all breeds. For Holstein the weights and optimum in the udder index have been changed.
