I have a lighter (450 lbs) steer that I purchased october 28th that I need to reach at least 1100 pounds at my show on august 19th...he is a high quality steer. What is the best, most efficient feed plan for him, any suggestions are welcome. Are there any feed supplements for him. I have 2nd cutting grass alfalfa hay mix that i free feed, and I purchased country acres sweet mix plus feed and started him on 4 pounds of that daily, he has fresh water and a mineral salt block at all times.
