[QUOTE="Ky hills, post: 1781617, member: 24816"] AI on its own merit isn’t shrinking the gene pool, however the way that it is being used certainly is playing a role in that. My reason for using AI years ago was to bring in outside genetics. At that time AI was not as widespread in the beef industry as it is now. Now in the Angus breed it’s very common for registered breeders to AI their whole herds at least the first round. So much importance is placed on AI sired cattle, that I know some breeders who will use a Hereford bull for example as a clean up on their registered cows as they apparently view a non AI calf as not worthy of being registered, but that’s another. conversation in itself. The way AI is being promoted now even though there are a lot of Angus bulls available, many of the breeders are using predominantly the same sampling of bulls or bulls with similar genetics in their pedigree. The example of Precision 1680 showcases the far reaching span of a heavily used sire. Heavily used bulls like New Design, Predestined, In Focus, Final Answer, show up in many pedigrees and then the sons and grandsons of them and others show up in various combinations on down the line. I do believe it is likely getting hard to find somewhat of an outcross within the breed unless you bring in some genetics from a more obscure source. Before the heavy reliance on AI, you would have more easily brought in a bull from a little different program either locally or regionally. or used AI to bring in outcross genetics. [/QUOTE]
