By submitting genotype and pedigree data to Nordic Cattle Genetic Evaluation (NAV), owners of Holstein AI bulls can choose to order GEBV for Interbull traits and/or GEBV for the unique Nordic traits.

Interbull traits include production, fertility, calving, longevity, conformation, milkability, temperament, and udder health – the same traits are evaluated by the other  members of the EuroGenomics Cooperative. The breeding values of AI bulls going through this process will be published in five different rankings: Nordic (DFS), Dutch/Flemish, French, Spanish and Polish.

The unique Nordic traits include claw health, young stock survival, growth, saved feed, persistency and general health. GEBV for these traits will only be published on the Nordic scale.

Submitting data

Owners of AI bulls older than 10 months can submit bull data to Nordic Cattle Genetic Evaluation (NAV) (see contacts below). They will then receive genomic breeding values for all Interbull traits and NTM (Nordic Total Merit Index) and/or the unique Nordic traits.

• The fee for the evaluation of one bull, including listing in official publications for Interbull traits and NTM, is €2000.
• The fee for the evaluation of one bull, including listing in official publications for Nordic traits, is €1 per sold dose of semen, with a minimum of 2.000 doses.

The official DFS genomic breeding values will be published on the NAV website. The EuroGenomics website, will show the genomic breeding values on the five national scales for the Interbull traits mentioned above.

Owners of Holstein AI bulls can also apply for a simplified genomic evaluation on only the Nordic scale for Interbull traits or the unique Nordic traits. This will result in unofficial (not for publication) genomic breeding values for Nordic traits and/or Interbull traits and NTM which will be sent to the bull owner by NAV.

• The fee for the unofficial results is €150 for Interbull traits and NTM
• The fee for the unofficial results is €150 for the unique Nordic traits

If you want to apply for a genomic evaluation you have to sign a contract for Interbull traits and/or a contract for the unique Nordic traits for each bull and the genotype and the pedigree data has to be delivered in the described format. Please, be aware of deadlines for sending DNA tissue for inclusion in genomic evaluation.

NAV har lanceret en ny søgeside, som viser avlsværdital fra Interbull på nordisk skala.  Denne side gør det let at finde de bedste tyre i verden.

Siden har næsten alle de samme funktioner som ”NAV – søgning på tyre”, og den er let at bruge. Tyrene kan søges ud fra ønsker til race, fødselsland eller fødselsår. Det er også muligt at sortere tyrene efter forskellige avlsværdital. Endelig kan man finde uddybende information på den enkelte tyrs egen side.

Avlsværditallene opdateres efter hver Interbull evaluering – altså tre gange om året. For RDC og Jersey er kun tyre som har avlsværdital baseret på døtre, men der for Holsten også er tyre som udelukkende har genomiske avlsværdital.

I forhold til tidligere, vil NTM for genomisk testede udenlandske tyre ikke længere blive vist på siden. For afprøvede tyre, både indenlandske og udenlandske, vil blive vist de samme informationer som tidligere.

Søgning på Interbull indekser kan findes på NAV startsiden.
