That all depends on the size of the steer and what his average daily gain is; it also has a lot to do with what kind of feed he's fed. The higher the quality, the more he'll eat; same with the level of moisture content. As such, the question cannot be answered in a "amount in terms of weight" basis. Maintenance is 2.5% of his body weight per day, but if he's given a higher quality ration that is suited for him to grow, he may consume anywhere from 3% to 5% of his body weight per day.
It all depends on what feed is being fed to that steer, as in what feed is available, what the ratio of forage to grain is for that steer, and the steer's breeding and genetics. Some breeds or crossbreeds of steers will require less feed to achieve a pound of gain than other breeds or crossbreeds. For instance, an Angus steer will gain a pound on less feed than a Simmental steer.
