April 2020 Evaluation Run is one of the historic runs for the ANARB because of the many changes.

  1. Implementation of the One-Step calculation method for sires

After using this method to calculate cow indexes for one year, we will be using it for sire also. All genomic records collected on the female population in the last decade can be finally used to improve the accuracy of the genomic evaluation of sires.

  1. Change of the fat and protein percentage calculation method

As it happened one year ago for cows, starting from this run the calculation of the fat and protein percentage calculation method for sires will change completely. The new method can identify the differences among sires of different ages and allows a more accurate comparison between the proven sires and the young genomic sires.

  1. New Genetic base for functional and production indexes.

To avoid changing the order of magnitude of the sires’ index we decided to use for all traits the same genetic base used for type traits. The genetic base is the reference point of all genetic indexes: all animals included in the base have an average index equal to 0 for the production traits and equal to 100 for the other traits. Starting from this evaluation run, we will be using a mobile base (updated for each evaluation run) which includes ll animals born from 12 to 15 years ago. Specifically, for the  April 2020 Run, the base includes all animals born from April 2005 and April 2007. This change will be visible in the cows’ evaluation without changing the ranking of the animals.

  1. Technical adjustment of the ITE

Since the new evaluation method calculates the genetic evaluation using a single rating scale- different from the one previously used – a slight technical adjustment to the ITE calculation formula. This adjustment allows applying the CTC  selection choices more correctly.  The resulted ITE variation is minimal for cows and negligible for sires.

The records of the new genetic evaluation are available  on line from Tuesday, April 7  at 12.am

Important news for the genetic and genomic evaluation of cows and heifers

In the index evaluation of April 2019, important news were introduced in the genetic and genomic evaluation of the female population.
Now cows and heifers are evaluated using the onestep method which, in addition to the information on bulls so far based on genomic evaluation, also uses information on the female population to improve the accuracy of the indices.
Furthermore, the evaluation for protein and fat percentages has been radically changed: now the calculation is based directly on the analysis data of the individual milk samples.

15 February 2019

From Monday 18 February 2019 the new ANARB database will be activated, for the genealogical book information.

From the same date the archive on the AS400 system will no longer be available.

The power of this new data base is based on the automatic and continuous acquisition of new data from Siall (LG events, productions, etc.) and of changes / corrections on existing data.

The consultation of information in aggregate form, the certifications and other services made available on Bruna online remain unchanged.
