Simbrah Registry – Breed Classification: Notice of New HerdBook Programming Logic for Purebred Simbrah Classifications.

In September of this year, the Trustees and Staff of ASA were notified of a concern regarding the Purebred Simbrah classification some animals received. Upon an in-depth review, ASA determined that the programming logic in HerdBook Services ( from 2013, gave an animal a Purebred Simbrah classification where another interpretation would classify these same animals as Percentage Simbrah.

The ASA Board met on Monday, November 28, 2022 and passed two resolutions which clarified the interpretation of the programming logic to be used for the Simbrah Registry – Breed Classification and provided for the implementation of the clarification.

The updated programming logic was implemented on December 15, 2022, (the “2022 Programing Logic”).
