Members with cattle in the upcoming spring sale, calving and show seasons should be cognizant of the 2024 donor dam rule change that may impact the ability to register embryo transfer (ET) calves.) The rule update, approved in 2024, states donor dams born on or after January 1, 2023, and used for embryo transfer must have DNA testing done including parentage markers and the complete genomic condition bundle for the genetic conditions monitored by the American Angus Association^®. This mirrors the longstanding requirements already in place for Artificial Insemination (AI) sires. 

Incomplete testing can lead to ET calves being placed in suspense, delaying registration. In the event DNA is unavailable from the donor dam for genetic condition testing, the full suite of known commercially available tests for the genetic conditions monitored by the Association will be required for all offspring applying for registration. 

Members can review Rule 104 d.2. in the Breeder’s Reference Guide.

If you have questions about donor dam requirements, genetic testing, or how these rules apply to your operation, the Association’s Member Services team is here to help; 816‑383‑5100 or angus@angus.org.
