Policy Established for DD Genetic Condition
The American Angus Association announced Aug. 12 that a genetic condition has been identified and documented in Angus cattle through research initiated in Australia with Jonathan Beever at the University of Illinois. This condition, inherited as a simple recessive, has been designated as Developmental Duplication (DD).
The Board of Directors convened by phone Aug. 12 to consider the implications of this genetic condition. At the conclusion of that meeting, President Phil Trowbridge appointed a Task Force and directed it to report to the full board as soon as practical how the Association should respond to this condition considering the best interests of the breed and the membership, the evolving scientific advances in the field of genetics, members’ ability to manage such conditions, and the likelihood that the scientific community will continue to identify genetic conditions in all breeds with increasing frequency in the future.
Trowbridge announced and explained the policy established with regard to DD in a letter to Angus breeders posted on the Association’s classic website (www.angus.org/angus.aspx
) Aug. 14.
Artificial insemination (AI) organizations requested the Association provide to the membership the identity of and preliminary test results for 1,099 Angus bulls tested by Beever to determine whether they were carriers or free of the mutation identified for this genetic condition. The Association Board of Director’s decision to provide that information to the membership is based in part on its understanding that the test used here was run on a set of animals requested by Beever from the AI organizations for research purposes and therefore remains preliminary in nature. (For an update on the research by Beever, the list of the animals and their preliminary test results, please click here.)
