CDCB GENETIC EVALUATIONS (04/25)

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.

 

 

 

The Progressive Performance Ranking (PPR) has been revised effective April 2025. 
Trait Weights include:  Protein, Fat, Udder Composite, Productive Life, Daughter Pregnancy Rate, Mobility, Livability, Somatic Cell Score, Cow Conception Rate, Heifer Conception Rate, and Early First Calving.

The Udder Composite (UDC) Formula has been revised effective April 2025.
Trait Weights include: Rear Udder Height, Rear Udder Width, Udder Cleft, Fore Udder Attachment, Udder Depth,
Front Teat Placement, Rear Teat Placement, and Teat Length.

Net Merit $ is the U.S. national economic index, designed to maximize a cow’s lifetime profitability. It ranks dairy animals based on their combined genetic merit for economically important traits. The guiding principle in the Net Merit construction is that index weights are based on an economic model that considers, as accurately as possible, incomes and expenses over the life of a dairy cow. Net Merit is a profit-driven selection tool based purely on economic value and trait reliability.

The U.S. dairy industry has evolved significantly since the last Net Merit update in 2021. While some trait weight shifts occurred in the 2025 revision, they were mainly within correlated groups, meaning the overall balance remains stable with previous versions.

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.
