Steer not eating Bermuda

For some reason my 10 month old steer won't eat Bermuda unless it's all that he has to eat. I'm currently giving him 3 pounds of cooked corn, 1 qt of un soaked beet pulp, 3/4 cups of corn oil, 2 handfuls of Sullivan's bloom fill, and 20 pounds a day of showtime grain. He currently weighs 795 lbs. if you have any other questions please ask and I'll let you know ASAP, thank you.

If it is good quality Bermuda grass hay that is palitable, he will eat as much of the hay as he needs.  If the was rained on in the windrow or is stemy and poor quality, then he will eat less of it and you should find a better quality hay.
