[QUOTE="simme, post: 1819825, member: 40418"] What does "pure" mean in a breed? Do people really believe that any breeds are "pure"? Were they created "pure" or did they evolve to "pure"? Whatever people or animals we have were developed over a long time by mixing genetics. At some point, some group of people decided they had achieved a breed and "closed' the herdbooks/genetics. Does that make them "pure"? Even if they are "pure", does that assure that you can "count on results"? For traits that are inherited from "pure" genetics (like color and polled), the answer is yes. But does that ensure that all the animals from that "pure" strain will always produce desirable offspring? I think maybe some people may be too devoted to the concept of a breed. If following that thought will maximize your success (however you measure it), then it is a valid approach. But, experience will show that crossbred animals will often perform better than "pure" animals. Why not take advantage of that increase in longevity in females, fertility in females, productivity, growth, etc if it exists. Even in bulls. Even in dogs. I will even say that I find it somewhat arrogant for the "pure" breed associations to say that all the genetics needed in beef cattle are already in their breed and no other genetics are needed. I know that outside genetics have improved the american simmental breed since the original imports. Simmental and simangus are popular now for a reason other than a love of purity and breed association. I also believe that simmental and other genetics have improved some of the "pure" breeds. Some of those "mutt" breeds make pretty good dogs and cattle. If we can get over our mental block about "purity". [/QUOTE]
