I agree with everything Caledon has said here. I used a bunch of Abricot and Extra in our herd as their daughters were good females. I don't remember ever keeping many bulls sired by them. Back in that era, I always thought the Swiss cattle were the most complete animals however they were smaller framed than the French bloodlines. I used to work for about a month each spring at Bar 5 prior to their sales, and I got to see many of the different Simmental bloodlines in the same herd. I loved some of their Swiss cows but they were not accepted at the time because of their smaller frames. The German/ Austrian lines were also more like the Swiss cattle in frame size but they were usually deeper fleshed and carried more leather through their necks and lower third.
I have often wondered about the temperament issues in many of these cattle. I have always felt that temperament is highly heritable, however, it did not seem to work that way with some of these Simmental sires. One of the quietest Simmental bulls I ever worked with was Lacombe Achilles, yet his offspring were oftentimes totally nuts. Bar 5 Dutch was a Fleck bull who had a very terrible disposition, yet his calves were very easy to handle. I remember Dutch keeping a duck hunter who had wandered into the pasture where he was, up a tree for 3 days before he was found. At Bar 5, we fed Dutch in the winter, by climbing a ladder and dumping some grain over a 8 ft fence into a trough. Most everything in his pen was totally destroyed.
I also agree that Bar 11 Ueli was one of the most overlooked bulls from that era. If a person could ever locate some semen for him today, it certainly would be worth a try. His daughters were great females and many of his bulls were excellent as well.
