In both of these experiments bran gives a much smaller daily 

 gain than either linseed or cottonseed-meal. In order to furnish 

 the desired amount of protein, it was necessary to feed from five 

 to six pounds per day to each steer, which quantity of this food, 

 rather laxative in its effects, caused the steers to scour both win- 

 ters. Several steers in the bran lot became more or less rheumatic 

 or stiff. This was also observed both winters, but it was more 

 pronounced in the second trial. No doubt, these difficulties were 

 partly responsible for the unsatisfactory gains on corn and bran. 

 No other lots were similarly affected, and it looks very much as 

 if the bran caused it. The bran put on the market today is ap- 

 parently less valuable than formerly, no doubt, because of its high 

 crude fiber content, due to modern methods of milling, which effect 

 a more complete extraction of the valuable portions of the wheat 

 kernel. 



While cottonseed-mxeal is slightly higher in protein than lin- 

 seed-meal, the latter gave the larger gains in both these experi- 

 ments, though the difference was not great. The cattle did net 

 eat the mixture of corn and cottonseed-meal with the sam^s relish 

 that was conspicuous when the ration corn and linseed-meal was 

 placed before them, and this, no doubt, furnishes one explanation 

 of the superiority of linseed-meal in producing not only larger daily 

 gains, but also larger gains from the same weight of food. The 

 feeds used in the first experiment cost as follows : Corn, 35 cents 

 per bushel ; bran, $15,00 per ton, linseed-meal, $32.00 per ton, and 

 cottonseed-m.eal, $32.00. Those used in the second experiment cost 

 as follows: Corn, 36 cents per bushel; bran $18.00 per ton; lin- 

 seed-meal, $29.50 per ton; cottonseed-meal, $27.75 per ton, and 

 stover, $2.50 per ton. The prices given for commercial foods are 

 on the basis of car lots delivered on track F. 0. B. Lincoln. At 

 the above prices it will be noted that the cost of producing one 

 pound of gain was much greater with bran than either of the other 

 foods. In the first experiment the linseed-meal proved to be three 

 times as valuable as bran. The difference was even greater in the 

 second experiment. It would not be wise, however, to place any 

 relative values upon these foods until after further tests are made. 



In examining the above table, it is interesting to note that 

 the gains made in the second experiment where corn-stover was 

 used as the roughness compared favorably with those made in the 

 first experiment on prairie hay. We can not, however, formulate 

 any estimate of the relative value of the two forms of roughness 

 from the above table, because the first experiment was of only eight
