Official CDCB Evaluations

The Council on Dairy Cattle Breeding (CDCB) releases Official Genetic Evaluations three times per year in April, August, and December. In order to receive a production or linear evaluation, a sire must have 10 milking, classified daughters. It is extremely important to make sure your cows are identified correctly on the DHI testing sheet, as incorrect identification will prevent them from being included in a sire’s proof. All animals registered or grade having sire ID are included in evaluations.

PPR (Progressive Performance Ranking):Sires and cows are now ranked by PPR, which includes Protein, Fat, Somatic Cell Score (SCS), Productive Life (PL), Udder Composite (UDC), Mobility (MO) and Daughter Pregnancy Rate (DPR).

NM$ (Net Merit): Previously, sires and cows were ranked by NM$, which included Calving Ability (CA$), Daughter Pregnancy Rate (DPR), Body Size Composite (BSC), 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 and now also include Cow Conception Rate (CCR), Heifer Conception Rate (HCR), and Milk.

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.
