graphs from the summary made by Professor Allison. 

 He says: 



A ton of silage, as used in this experiment, was ap- 

 proximately equal to one-half ton of clover hay. 



Estimated on the basis of net profit per steer, a ton 

 of dry matter in the form of corn silage yielded 50.3 

 per cent greater value than a ton of dry matter in the 

 form of shock corn. 



It is evident from the data given that it takes less 

 grain in the form of shelled corn to fatten two-year-old 

 steers when corn silage composes a part of the ration. 



A superior finish is obtained on fattening cattle 

 which are marketed in the spring when silage composes 

 a part of the ration. 



A similar experiment at the Iowa station brought 

 practically the same results. Regarding it, Prof. John 

 M. Evvard stated that "the silage-fed cattle, without 

 a single exception, returned greater profit than when 

 clover was fed as the only roughage. By using silage 

 the gains in weight were cheapened and the profit per 

 steer increased." 



Some very valuable cattle feeding tests have been 

 conducted at the Pennsylvania State Experiment Sta- 

 tion, among them an experiment to determine to what 

 extent silage could profitably be used in steer feeding. 

 This experiment lasted 126 days. The results of the 

 test are given in detail by Prof. W. A. Cochel, in Bulle- 

 tin No. 118, issued by the Pennsylvania station. 



The results of this experiment are interesting at 

 this point, not only because silage formed a part of the 

 ration used, but on account of some valuable data de- 

 rived, showing that during the early part of the feed- 

 ing period some ear corn or shelled corn can profitably 

 be replaced by silage.
