Thanks Ryan and Josh. I've copied and pasted a note from Wayne at the Center from last year, when I asked for details on the ration. Please see below. I've got the Lab reports also. If you'd like to see that, please email and I will send a copy.
"Mr Larson
The bulls were fed a hay based, high roughage ration. The ration was designed for the calves to have an average ADG of 3 pounds. To date this goal has been achieved as the ADG for all four pens of bulls is 3.1 pounds. The ration has allowed the bulls to express their genetic capabilities and have separation in performance of the calves.
The ration during the test would average: 45% ground alfalfa/grass hay, 35% corn, 10% wheat midds and 10% liquid supplement. This allowed the bulls to grow at the desired rate and remain sound.
I hope this is what you wanted. If not, let me know."

As far as heifer development goes, I subscribe to the belief that heifers should be developed as closely as possible to the way they will be managed as cows. I think that this contributes greatly to their longevity and structural soundness. Our heifer calves are fed "free choice" round baled hay provided in several feeders that are placed in a way that tries to minimize ground damage. I try to give them a variety. Some is straight meadow grass, some wheat hay, some medium quality alfalfa. Breed up doesn't seem to be a problem. Last year, we AI bred 20 yearlings with a simple 2-shot protocol followed by observation and then timed breeding. Of the twenty head, 13 conceived for a 65% success rate. I have tried much more complicated breeding protocols in the past, with no better results, but much more intensive management.
