Feed questions

This is our daughter's second year showing a steer project in 4-h (she is 10).  Last year's steer would eat and eat and then eat some more - weighed in at our county fair at 1400 lbs.  This year's steer is a picky eater at best (they would usually only eat 3/4 of their feed each feeding) - after looking on here we have fed him probois for 4 feedings and they are now licking the feed bunk clean (24 lbs. grain fed to 2 steers 2x a day - 12 lbs. of a show feed similar to ADM and 12 lbs. of our own grind and  mix which consists of shelled corn, oats, SBM, liquid molasses and minerals mainly).  I am wondering if cooked barley or corn will help him out - 2 weeks ago he weighed 855 and was 48 3/4 inch hip height at an April show.  Our fair is middle of September.  He is growing hair like a maniac with rinsing and blowing dry 5 times a week (he gets clipped every 2 -3 weeks to keep it under control) and is under 2 fans in the semi-dark.  He is in with a companion calf who is her carcass animal.  Also, how long should we feed the probios for?  Any help would be appreciated!  Thanks!!!

Sounds like your right on target for september I wouldn't worry about cooked corn until about mid july if you think he will need more cover and probios I would give him once or twice a week if you feel he needs it
