RDC has adjusted weights in NTM

At the same time as including youngstock survival in NTM, RDC is changing the weights for some other indices in NTM. Weight on yield and udder conformation is increased slightly. This is done to secure that genetic progress for these traits are maintained when introducing youngstock survival in NTM.


The change has only limited effect on ranking of bulls.


All the current weights for different sub-indices in NTM and the correlations between NTM and sub-indices can be found on NAV web page (www.nordicebv.info) under NTM and breeding values/NTM.
