[QUOTE="Beef11, post: 285849, member: 2705"] "In Theory" if we as an industry are making any genetic progress than the newer bulls should be better than the older bulls. If a good bull 20 years ago was really good he should have progeny that was better than himself and they in turn at some point in their productive life would produce progeny better than themselves and so on through the generations. This in mind why would we use a bull that is old enough to be stored in ampules? My theory on breeding is use the best available and try to produce better. [/QUOTE]
