Guys, go and check out the details on the AICA website for Trait leaders, bulls that on on the mutiple trait list should be excellent canidates for AI sires... Bulls like 914, 9108, Cigar, and Wyoming Wind the semen prices are to high from $100 to 350 in the last year for a single straw. Let the Purebred breeders use those sires and spend that type of money.
A couple of bulls that have been doing extremely well across the board is Gridmaker 104, Gain & Grade 927, and then i like the Polled Value 9089 bull for daughters. 104 is going to add thickness and extra muscle defination along with great spring of rib. 927 is a flatter muscled bull, daughters make excellent mothers though and he is in the top 1% for marbling and daughters will pass that on. 9089 is a bull that has been used extensively in a few herds, the daughters in production show very moderate frames, amazing, almost perfect utters, but i was expecting more performance out of them, they flesh easy, breed fast and produce a good amount of milk for the calves, so keep the females out of him... Use those bulls for results that you don't have to take a chance on. Some of the other bulls mentioned in above posts i have not heard of and I have been a purebred breeder since 1985. That's taking a change on an entire generation of calves, can you gamble that much ??
