Revised Conformation Traits – December 2016
Conformation trait evaluations for non-Holstein breeds were revised with the December 2016 run. New genetic evaluation software implemented in 2014 for production and most other traits is now also applied to linear type traits, final score, milking speed, and mobility. Details can be found on the CDCB website under “Changes to evaluation system (December 2016)”. https://www.cdcb.us/reference/changes/eval1612.htm. Average correlations of new with previous PTA’s for linear traits were 0.969 for Brown Swiss. Some individual traits may have seen more fluctuation such as Rear Udder Width.
