In the investigations that have been made in the economical production of beef, the main factors receiving consideration have been the production and fattening of native steers and the fattening of those obtained from the range. The experiments connected with the making of beef from native steers included studies of the possibilities of making a combined profit from the steers and also from the cows that produced them, the use of skimmilk for economy in feeding and the employment of a wide and a narrow ration in feeding. These are reported on somewhat independently, though they have a bearing on the general question of producing beef economically under the conditions of Iowa.
