Five A.I. organizations requested that the American Angus Association provide to the membership the identity of and preliminary test results for Angus bulls tested by Dr. Jon Beever of the University of Illinois to determine whether they were carriers of the Curly Calf Syndrome (CCS) mutation or were free of it. In doing so we provide the following overview of our understanding of how these results came into existence and the Association’s view of their current significance. Throughout September and October, it is our understanding that Dr. Beever contacted a number of A.I. organizations to request that they voluntarily provide him with semen samples from bulls in their inventory for use in his research into CCS. His requests included samples from animals both with and without the genetics now in issue. The Association did not participate in or provide any input into the selection of those samples that were submitted.
As the Association reported to the membership on October 24, Dr. Beever informed us that he had developed a preliminary test, although it was not yet what he considered optimal. We understood that it was an important, initial step toward validation and ultimate commercialization.
On October 27, we learned that Dr. Beever began to transmit results of those tests he had conducted on the samples provided to him to each of the submitting A.I. organizations. These results indicated for each animal that underwent this preliminary test whether the animal in question was a carrier of the CCS mutation or was free of it.
