More Genomic Breeding Values on the Nordic scale
What is NTM and gNTM?
The NTM for “Production and Functionality” is the total merit index that is used in Denmark, Sweden and Finland for ranking bulls according to the Scandinavian breeding goal.
What are the benefits of using NTM?
NTM is a balanced breeding goal that aims for healthy, fertile, well producing and long-lasting cows with good conformation. With NTM you are breeding for improved profit (see leaflet: http://www.nordicebv.info/wp-content/uploads/2015/04/NTM-folder-ENG-web.pdf).
How to understand NTM?
- 95% of the bulls of the Holstein animals evaluated in the Nordic Countries have breeding values between -20 and +20. This means that bulls with a proof over 20 represent the top 2.5% of the breed.
- Breeding values on the Nordic scale have an average of 0 and a genetic standard deviation of 10.
- One NTM-unit is worth approximately 10 Euros extra per cow in one year.
Who is responsible for estimation and publication of breeding values?
NAV is computing genomic breeding values on a monthly basis for more than 40 traits and 13 groups of traits. Here are the dates of the NAV genomic evaluation: http://www.nordicebv.info/events/
SEGES, VÄXA Swerige and FABA are responsible for the publication of breeding values for sires in Denmark, Sweden and Finland respectively.
Where do you search for the NTM of a specific sire?
NTM and all other breeding values calculated by NAV can be found for all bulls with or without a Nordic herdbook number on NAV official website.
