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.
