STEER FEEDING EXPERIMENTS 263 



Lot V consumed an average of 28.33 pounds of corn silage 

 for the entire period. During the first 56 days when no grain was 

 fed they averaged 37.584 pounds daily., This amount was greatly 

 reduced as soon as grain was added to the ration, averaging 21.36 

 pounds per head daily during the grain feeding period. This re- 

 duction in the amount of silage fed was necessary to induce .the 

 cattle to consume their allowance of alfalfa hay and grain. The 

 quantity of alfalfa hay consumed varied little during the test, but 

 increased gradually with the increase in weight of the cattle. The 

 full allowance of &/2 pounds of cottonseed meal per 1000 pounds 

 live weight was consumed daily. An average of 12 pounds of ear 

 corn was consumed during the two months in which it was fed, 

 and 11.94 pounds of shelled corn was consumed daily during the 

 last month. 



The amount of air-dry matter consumed by four-week periods 

 is quite uniform in Lots II to V, inclusive, for both the first and 

 second four-week periods. Lot I, receiving grain in the ration, 

 but no silage, consumed 20.586 pounds of dry matter daily, as 

 compared with 17.912 pounds of air-dry matter for Lot II, which re- 

 ceived corn silage only as roughage. The average amount oS air-dry 

 matter for the four lots,- receiving no grain except cottonseed meal 

 and silage as all or part of the roughage, is 17.933 pounds for the 

 first four weeks, as compared with 20.586 pounds per head daily 

 for the lot receiving grain and no succulent feed. The same gen- 

 eral relation continued during the second four-week period, except 

 that the amount consumed by Lot I was greater than in the preced- 

 ing four weeks and lower in the other lots. Lots II to V, in- 

 clusive, averaged 16.107 pounds per head daily as compared with 

 22.332 pounds per head daily for Lot I. During the third and 

 fourth four-week periods there was very little difference in the five lots. 

 A further marked difference was noted in the fifth or last four- 

 week period. Lot I continued to consume 22.410 pounds per head 

 daily, while the other lots dropped to an average of 20.025 pounds 

 per head daily which was due to a more concentrated grain in the 

 form of shelled corn. The average amount of air-dry matter con- 

 sumed for the entire 140 days was highest in Lot I and lowest in 

 Lot IT which was due entirely to the character of the ration fed.
