Due to the number of unknowns associated with DD and its inheritance and the increasing number of genetic conditions, the Board decided to continue monitoring DD closely but at this time will not add DD to TraitTrac. In lieu of adding DD to TraitTrac, we will report DD test results in Simmental-influenced animals on our herdbook homepage https://herdbook.org. This list will be updated as new results are reported.
