[QUOTE="cbcr, post: 1155553, member: 16303"] We certainly understand a breeding up and a breeder needing to start from somewhere. As far as EPD accuracy, even though the ASA is supposed to have a multi-breed evaluation, if the percentage of the other breed compositions is not known the the accuracy on 1/2 bloods will not be as accurate. Even with known parentage this could be the case. The reason why would be not knowing which traits or how much of each trait is available from the contributing breeds. However if these crosses are bred together, by some consensus from some experts in genetics by the third cross the accuracy would begin to be stabilized. We have 2 registries, Beef and Dairy, and in the process of grading up we require a minimum percentage to be at 87.5% which is pretty much as industry standard for purebred. Our feeling for composites is that for a composite to be considered as a purebred, they should be a 5/8 x 3/8 percentage. However in order to add newer genetics, 1/2 and 3/4 blood animals would be needed to create new purebreds of 5/8 x 3/8. [/QUOTE]
