From May 2022 Jersey changes the weight on Claw health in NTM from 0.04 to 0.09. All other weights are unchanged. This will nearly double the genetic progress for Claw health, and it has almost no effect on the genetic progress for the other traits in NTM.
It will have a limited effect on ranking of bulls and cows. A bull with 120 for claw health gets an extra unit in NTM because of this change.
The second NAV routine evaluation for this year took place as scheduled. NAV Bull Search has been updated with new EBV’s and GEBV’s.
For Jersey, the weight for claw health in NTM was slightly changed. This increases the expected response for claw health and has very limited effect on the genetic response in all other traits.
In NAV Bull Search, two new genetic traits were included for Holstein: Red factor and dominant variant red factor.
NAV Beef Search is also updated with new beef x dairy breeding values.
