to made on tlie maintenance feeding of cattle have been 

 with various forms of coarse fodder. The plan of winter- 

 ing fetoek on corn nioal exclusively, which is adopted by 

 Mr. L. W. Miller, has already been alluded to, and pres- 

 ents such a strong contrast to the ordinary system as to 

 merit some consideration. 



Mr. Miller's experfments have been made on dry cows, 

 and he states,"'^ as the result of several seasons' experience, 

 that three quarts of good fim corn meal per day, fed dry 

 and without other food, are abundantly sufficient to supply 

 the wants of a 900 pound animal. 



It is of interest to compare this ration with the feeding 

 standard deduced above. Assuming three quarts of meal 

 to weigh 4r.2 lbs., and that the corn meal has the same 

 composition as the average of American maize, viz. : 



Water 10.47 per cent. 



Ash 1.50 " 



Protein 10 96 " 



Crude fibre 1 73 "

 observed for maize, viz. :
