Replacement heifers or feedlot heifers.  You don't want replacements on full corn.  As far as cattle in general on steer stuffers, I'd guess at least 90% of them are holstein steers.

How do you limit intake?  You don't.  They eat as much as they want.  Work them up to full feed over a few weeks and they'll be fine

How do you keep from bridging/freezing? Never had feed bridge.  Chisel frozen crap from opening as needed.  

What analysis of feed do you use? None.  Corn is corn.  Mix in pellets per directions on label.  Find a pellet you like and run with it.

Just to repeat myself, replacement heifers on full corn is a really bad idea.
