cent, of the money value of the essential fertilizmg con- 

 stituents, {. e., nitrogen, phosphoric acid and potassium 

 oxide, it contains. 



The statements of the relative proportion of the digestible 

 nitrogenous and non-nitrogenous food constituents of the 

 daily diet (its nutritiA^e ratio) are based on the mean of 

 more recent observations in connection with actual feedino- 

 experiments elsewhere (Wolff). 



The difterent daily fodder rations recorded below were 

 compounded with a view to compare ditferent comliinations 

 of well-known feed stuffs with reference to feeding effect 

 and to influence on cost of feed. Those daily fodder rations 

 which have given us the most satisfactory results in this 

 connection may be seen below (rations I. and II.). 



The general history of the management of the experiment 

 and the financial results of the whole operation are published 

 upon a few sul^sequent i)ages. It is for obvious reasons not 

 advisable to enter at this early stage of our experiments 

 upon a detailed critical discussion of the lessons which may 

 be learned from the results obtained. Some facts, however, 

 brought out in the course of the experiment, are apparently 

 so well supported under existing circumstances that a brief 

 statement concerning them may claim some special attention. 



Iiesullii. 



1. Corn ensilage, when fed either with wheat bran and 

 gluten meal, or with wheat bran and old-process linseed 

 meal, has produced in our case, without an exception, the 

 highest gain in live weight, as compared Avith other fodder 

 rations used in the experiment (see fodder rations I., II., 

 l)elow) . 



2. The increase in live weight per day, when feeding the 

 ensihige fodder rations (I., II.) to one-year old steers, has in 

 one instance (steer 2) exceeded three pounds, while in the 

 case of two-year old steers it lias averaged more than four 

 pounds per day in one case (steer 4). 



3. The original cost of the feed (corn ensilage, fodder 

 rations I., II.) consumed i)er day has been from 12.82 

 cents to 14.72 cents in case of one-year old steers (1, 2),
