TIONS COMPARED The beef raiser has not only to decide what are the most effect ive and economic grains and the best combinations in which to feed them, but also the amounts which may be fed with the best results and greatest profits. This problem has been studied by Ken nedy and others at the Iowa experiment station. After the steers had been brought to a proper feeding condition, the rations were gradually increased until one lot received 16, one 19 and one 21 pounds daily each bead. The grain was shelled corn, but later on in the experiment supplemental feeds, such as gluten feed and other nitrogenous materials, were added to bring the steers more rapidly to a fine finish. On the light grain ration, the amount of grain required for each pound of gain was 10.95 pounds, and the amount of rough age 9 pounds; while the average cost of each pound of gain was 9 cents. On a medium grain ration each pound of gain required the consumption of pounds of grain and pounds of roughage, and cost 9.1 cents. On the heavy grain ration each pound of gain required 12 pounds of grain and 61/2 pounds of roughage, and cost 9.2 cents.

Gains can be made more economically with a light or medium grain ration than with a heavy one; but in a feeding period of 189 days, it is not possible to finish cattle on light or medium grain rations so as to bring the top market price. The difference in the selling price of cattle fed a heavy grain ration is more than enough to offset the cheaper gains made by steers on light and me dium rations, so that in the end the greater economy is found in the heavy rations. Judging from the gains made by hogs following the various lots of steers, it seems that the grain was more perfectly digested by the steers which received the light and medium rations. In Kentucky, good results were ob tained by increasing the rations during the fattening period, so that at the end of the period the steers were receiving from 20 to 24 pounds daily of ear corn or corn and cob meal; or, when supple mental feeds were added to the corn, 13 to 20 pounds of corn meal and 2 to 6 pounds of cottonseed meal, or 4 pounds cottonseed meal and 4 pounds bran.

Shaw attempted to determine the most economic ration of barley for fattening steers in connection with clover hay as roughage. It is believed as a result of this experiment that when alfalfa or clover hay is used as the roughage, not more than 1/2 pound of barley or a similar grain to each 100 pounds of live weight is necessary to produce the most satisfactory results. The extra gains derived from the use of heavy grain rations sometimes fail to compen sate for the extra cost of the ration.
