CDCB Genetic Evaluations

Please Wait a Moment


All bulls on U.S. Genetic Evaluations have been submitted to Interbull. These evaluations are considered official by BSCBA and should be recognized as such.

  • Top 300 PPR Cows
    Cows must have calved within 27 months of the current run date to be eligible.  The printed final score was received prior to 68 months of age as of the current run cutoff date.


Progressive Performance Ranking (PPR) has been revised effective Dec 2020. 
Weights include:  Protein, Fat, Productive Life, Udder Composite, Mobility, Daughter Pregnancy Rate, Livability, and Somatic Cell Score.

NM$ (Net Merit): Previously, sires and cows were ranked by NM$, which included Calving Ability (CA$), Daughter Pregnancy Rate (DPR), Body Size/Weight Composite (BSC/BWC), Feet and Leg Composite (FLC), Udder Composite (UDC), Productive Life (PL), Somatic Cell Score (SCS), Fat and Protein.
NM$ ranking weights were revised in December 2014, April 2017, August 2018, August 2020, and August 2021, and now also include Cow Conception Rate (CCR), Heifer Conception Rate (HCR), Milk, Livability, Health Trait $, Heifer Livability, Feed Saved (Residual Feed Intake and BWC), and Early First Calving.

August 2020, the Calving Ability Index (CA$) formulae were revised for Brown Swiss and Holstein:
Brown Swiss:  -6 * (SCE - 3.0) - 8 * (DCE - 2.8)
Holstein:  -4 * (SCE - 2.2) -3 * (DCE - 2.7) -4 * (SSB - 5.7) --8 * (DSB - 6.6)
Also, the standard deviation for CA$ changed from 10 to 8 for Brown Swiss and from 18 to 14 for Holstein.

Performance Summary

The Performance Summary is published three times per year at each Official CDCB  Evaluation. It contains complete traditional and genomic type and production data for sires, cows and heifers and is a useful tool for making mating and marketing decisions.
