I've been around cattle all my life, and I've always been interested in matings and pedigrees...what works and doesn't work. We've shown a few, and we sell a show heifer every now and then...our business is mostly commercial bulls and replacement heifers. I get that a lot of people see the industry as very segmented...production cattle, seed stock cattle, commercial cattle, show cattle...but they're all cattle, and the same rules apply to cattle breeding, regardless of which segment you're involved in.
This is my advice to you: Have a game plan. Have a clear and concise direction for your breeding program and focus on what you want to produce. Don't chase the fads or use the bull that won the last big show just because he won the last big show. If you breed to that bull today, reality is there will be a few more big shows before that calf is ever born, and the bull that won today may or may not be popular at all. If he fits your breeding program and you decide to invest in those genetics, be sure it's for reasons that are connected to your goals as a cattle breeder.
I can't take credit for the next part--and this is important...I think I heard this advice on this forum, and I don't remember who said it...I don't even know if that person came up with this himself or if he was quoting somebody else, but the advice stuck, and it's as sound as it gets: Don't try to breed good show cattle...try to show good breeding cattle. If your breeding program is based on creating a show winner, you are spinning your wheels. Instead, know your cow herd, study your lesson, and become a student in the art of cattle breeding. Make it your goal to improve every generation of cattle your raise, and you WILL make progress. It isn't fast, but it is steps in the right direction. And you might accidentally make a show winner or two along the way.
I know that doesn't answer your questions about what bull to use this year on this cow or that cow. Like I said, I'm not a club calf man. I don't like terminally bred cattle at all. I can appreciate a really pretty show steer as much as the next guy, but those cattle are next to impossible for the average breeder to create. And if you're always trying to hit a home run, it can be impossible to get a base hit. It can turn into a game of all or nothing.
I would actually think about an extremely sound, functional Simmental or SimAngus bull on cows like that. There are a bunch out there that have plenty of eye appeal, and Simmental cross is a cross that works like magic on a lot of breeds and kinds. You have a lot of options in terms of production-oriented type, calving ease, soundness of structure, and maternal ability. Especially if this mating results in a heifer, I think you could be way happier with the end result. Just food for thought...
