pounds live weight. The amount of corn silage .consumed daily 

 was materially reduced as soon as ear corn was added. The aver- 

 age amount consumed daily during the first two periods was 47.48 

 pounds, while during the time grain was fed the amount consumed 

 was 30.63 pounds per head. The cattle were started on six pounds 

 of ear corn per head, which amount was increased daily until the 

 full allowance was fed at the end of two weeks. The average daily 

 amount of grain consumed per head in Lot II was 9.72 pounds as 

 compared to 15.08 in Lot I to which grain was fed from the begin- 

 ning. 



Lot III consumed an average of 40.419 pounds of corn silage 

 during the first two months, or "roughage feeding period." 

 They received daily 33.3 pounds per head at the beginning of the 

 trial, the amount being gradually increased as rapidly as they would 

 consume it. The maximum amount consumed at any time by this 

 lot during the second period was 42.75 pounds. The amount of 

 silage was greatly reduced toward the end of the experiment, which 

 was necessary so that the cattle would consume the allowance of 

 alfalfa hay and grain. The average daily consumption of silage for 

 the last three months was 25.576, or 17.18 pounds less than when 

 no grain was added to the ration. The alfalfa, used as a source of 

 protein, was fed daily at the rate of 3.75 pounds per head at the be- 

 ginning and gradually increased to the full allowance of 5 pounds 

 per looo pounds live weight. This lot of cattle consumed daily an 

 average of 12.04 pounds of ear or shelled corn per head during the 

 time that grain was fed. 



Lot IV consumed an average of 19.67 pounds of corn silage 

 throughout the entire experiment. This was nearly their full al- 

 lowance of 20 pounds per head daily. They consumed daily an 

 average of 6.99 pounds of mixed hay per head for the entire feeding 

 period. During the first 56 days or, "roughage feeding period," 

 they consumed daily 9.88 pounds of hay per head which amount 

 was greatly reduced as soon as grain was added to the ration. The 

 full allowance of cottonseed meal was consumed as fed throughout 

 the entire experiment. The grain allowance averaged 12.03 pounds 

 per head daily for the third and fourth months while ear corn was 

 fed. An average of 1 1.975 pounds of shelled corn was consumed 

 during the last month of the experiment.
