The cattle feeder’s main purpose is to get the largest possible returns from his cattle with the amount of feed, capital and labor that he has available. Naturally, returns from the farm as a whole are more important than the success of any one enterprise, but the management of the entire farm involves many more questions than we can discuss adequately in this short bulletin. Therefore we shall simply present information obtained in 1938 and 1939 on the more common methods of Iowa cattle feeders. Results will be discussed solely on the basis of the cattle-feeding enterprise itself.
