Reissue of April 2022 Holstein Genetic Information

New official U.S. genetic evaluations will be released on Tuesday, April 12. The April 12 evaluations will replace the evaluations initially published on Tuesday, April 5, for Holstein animals.

Data from the December 2021 genetic evaluations for conformation traits on females were mistakenly loaded onto the Holstein Association USA (HAUSA) database and sent to the Council on Dairy Cattle Breeding (CDCB). This error significantly affects the Predicted Transmitting Abilities (PTAs) of recently-classified cows, the genomic evaluations of bulls adding a large number of newly-classified daughters, as well as their descendants. Traits affected include, PTA Type, linear type traits, overall type composites, Feed Saved, and the indices Net Merit $ and TPI™. Only evaluations for the Holstein breed are affected.

Older cows and well-proven bulls should show little change. The international proofs are unaffected as only bull data from our traditional genetic evaluations contribute to MACE. U.S. genetics websites (CDCB, HAUSA) will be refreshed with new information on Tuesday, April 12, at 7:00 am EDT. Individual animal queries will be updated and released at that time. New files (CDCD file 38, CDCB genomic files and HAUSA Type Files) will be reissued for our industry partners on April 12.

We sincerely apologize for the inconvenience that this causes and the subsequent delay in completing the April 2022 genetic update.
