[QUOTE="cbcr, post: 817020, member: 16303"] Breed Association EPD’s and Multi-Breed EPD’s As we have said in previous posts, with our genetic evaluation, an Angus can be compared to a Hereford, and likewise these two animals can be compared equally with any other breed such as Simmental, Brangus, Shorthorn, or even a Composite animal with more than one breed such as an Angus/Hereford, Angus/Shorthorn/Simmental/Gelbvieh, and the list and combinations can go on and on. The system that we use is truly multi-breed in all aspects (meaning Angus, Shorthorn, Charolais, Red Angus, Brangus, Gelbvieh, Simmental, Maine Anjou, Composites, etc.) , which makes it globally unique. Our model has extensive central test data, which many breeds do not include in their evaluations. The most recent genetic evaluation that ran last week included 2.5 million animals. The animals in the database are a mixture of purebred (different breeds), and Composite cattle of various breed compositions. There are other multi-breed models out there (e.g. run by the American Simmental Association as developed at Cornell University), but they are applied to data bases from a single Breed. These data bases will have crossbred cattle if used by that breed, but are not really multi-breed because they are mostly limited to a single breed. AGI and a small handful of others (using the model as developed at Cornell University), and BreedPlan offer evaluation services to breed associations. We are not aware of any joint analysis of data from more than 1 (or a very small number of) breeds at a time. Seedstock producers have been asking for true multi-breed evaluations, which so far has not happened. The biggest obstacle in the way for a true multi-breed evaluation to happen is for ALL Associations and Registries to share data. But because of politics within Associations and Registries this will be an almost impossible task. Calls and conversations with individuals with different breeds are applauding our efforts and what we are doing. [/QUOTE]
