Description of genetic evaluation 

Next publication dates for main evaluations with update of all domestic and international animals

  • 7th December 2021
  • 5th April 2022
  • 9th August 2022
  • 6th December 2022

New active AI bulls are updated on 1st Tuesday every week from the weekly genomic evaluation inbetween the main evaluations.

Official results

Data base German AI bulls (bull search)

Included are all A.I. bulls from Germany, Austria and Luxembourg. You can find individual bulls or select bulls for every individual trait or a combination of traits at the same time. Every individual bull can be printed as catalogue page. Click on "bull database" to be connected.

Haplotype status AI bulls

vit provides on behalfe of the German Livestock Association (BRS) lists of German and foreign genotyped Holstein AI bulls with results for Holstein Haplotypes HH1-HH5 and for Cholesterol Deficiency (CD). Results are either
- direct results on the base of identified and analyzed mutations (results with extension ‚**F‘ for ‚free‘ resp. ‘**C’ for ‚carrier‘)
- or imputed i.e. indirect results (results with extension ‚**N‘ for ‚non-carrier‘ resp. ‘**P’ for ‘probably positive’)

There are separate list for domestic and foreign bulls:

Haplotype_status_for_domestic_A.I._bulls.pdf

Haplotype_status_for_foreign_A.I._bulls_used_in Germany.pdf

Lists are sorted in alphabetic order. They can be searched e.g. by bull name or bull ID using ‘ctrl+F’.

Data quality at its best

On behalve of the dairy cattle breeding associations in Germany, Austria and Luxembourg vit evaluates all economically important traits for Holstein, Red Holstein, Red Dairy Cattle  (Angler), Red&White dual purpose (DN), Black&White Friesians (DSN) and Jersey breed three times a year based on own and offspring performance data (classical genetic evaluation). Genomic breeding values for all traits are calculated weekly for Holstein and Red Holstein and provided/published for new animals.

vit is the responsible authority for the data exchange with the international genetic evaluation at INTERBULL for all mentioned breeds. Since 1996, vit has also been evaluating breeding values for beef cattle breeds. The three Baltic countries and Poland are working with vit applications within the framework of a co-operation for genetic evaluation for dairy cattle populations.
