The CDCB and USDA AGIL team describes changes implemented for the triannual genetic evaluations on December 3, 2024, including updated calculations for Residual Feed Intake, integration of foreign evaluations with the new Rear Teat Placement in Brown Swiss, and exclusion of some crossbred animals in Net Merit $ trends.

The U.S. dairy industry will see a new symbol with genetic evaluations – Powered by CDCB – when the information is provided by the Council on Dairy Cattle Breeding (CDCB). Use of this mark increases transparency in genetic evaluations, helping producers connect the quality and sources of information they use for breeding and management decisions.
August 13, 2024
In the August 2024 evaluations, implemented changes had effects on all yield traits (Milk, Fat and Protein) and Heifer Livability, along with correlated traits of Productive Life and Cow Livability in some cases. Breed Base Representation (BBR) values were updated, with the annual reference population update and introduction of a revised SNP list.
July 11, 2024
CDCB and USDA AGIL detail changes implemented for the triannual genetic evaluations on August 13, 2024, including 305-AA as the new standardized yield measurement, full implementation of Constructed IDs, Heifer Livability updates, Brown Swiss Rear Teat Placement trait, new SNP list, annual BBR update and inclusion of HH6 and JNS gene tests in haplotype calculations.
June 21, 2024
Beginning in June 2024, the Council on Dairy Cattle Breeding’s (CDCB) publication of 305-ME (Mature Equivalent) will be discontinued and replaced by 305-AA (Average Age) as the standardized yield estimate for U.S. dairy cows.

CDCB and USDA AGIL announce enhancements in the U.S. dairy genetic evaluations on April 2, 2024.
November 16, 2023
Changes for the December 5, 2023, CDCB evaluations include updated imputation results for all breeds, new haplotype calls for early onset muscle weakness syndrome in Holsteins, and update to the haplotype calls for cholesterol deficiency in Holsteins.
