in the combinations fed. The amount of cottonseed meal varied 

 little for the three lots receiving- it as a source of protein. The 

 amount of ear and shelled corn varied but little for Lots II, III, 

 IV, and V. Lot I consumed considerably more grain than any 

 other lot, as it received grain from the beginning- of the feeding 

 trial. 



Table III is presented to show the average amount of feed con- 

 sumed daily by each steer by twenty-eight day periods. Each lot 

 of cattle was started on feed gradually and brought to a full feed 

 as rapidly as possible. Lot I was started on 4 pounds corn stover 

 per head daily, the amount being increased until at the end of ten 

 days they were receiving five pounds per head daily, which is the 

 maximum amount received at any time. Mixed hay was fed at 

 the rate of 8 pounds per head daily at the beginning and gradually 

 increased to ten pounds per head daily. The grain mixture of 

 three parts corn and one part bran was fed at the rate of 6 pounds 

 per head daily at the beginning and gradually increased until at 

 the end of two weeks the cattle were receiving i2 l / 2 pounds per 

 head daily. This amount was increased as rapidly as they would 

 consume it The average amount of corn stover consumed per 

 head daily was greatest during the first four weeks. It was gradu- 

 ally decreased each period except the fourth when a little more 

 was consumed than during the preceding four weeks. The amount 

 of mixed hay consumed per head daily varied little. The maximum 

 amount was 9.81 pounds per head daily, the minimum 9.57 pounds 

 per head, or an average for the entire feeding experiment of 9.67 

 pounds per head daily. The grain consumed was gradually in- 

 creased during each period, 11.34 pounds being fed during the be- 

 ginning, period and 16.31 pounds during the final period, or an 

 average of 15.08 pounds per head daily for the entire feeding 

 period. 



At the beginning of the experiment Lot II was fed daily 33.3 

 pounds of corn silage per head. This amount was increased to 37.5 

 pounds after the third day and to 50 pounds at the end of the i6th 

 day. For a short time during the second period, this lot received 

 54 pounds per head daily. The cottonseed meal was gradually in- 

 creased from onq pound per 1000 pounds live weight at the beginning 

 of the test until at the end of the first week they were receiving 

 daily their allowance of 2 l / 2 pounds of cottonseed meal per 1000
