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.
