of work to be performed ! A common daily feed for cart- 

 horses in South Lincolnshire is in winter composed of : 



Corni - - 14 pounds. 

 Cut straw - 20 

 Mangels - - 21 



What digestible matter is furnished by a diet of this 

 description ? To calculate this (and as it is of frequent 

 use it may be as well to state it fully) we refer to the 

 table of digestible constituents (p. 213), and, taking each 

 constituent separately, multiply the percentage by the 

 number of pounds of food taken, move the decimal point 

 two places to the left {i.e., divide by 100), which will give 

 the number of pounds of that particular constituent in 

 the weight of food given. 



For instance, how much digestible albuminous matter 

 is contained in 7 pounds of maize ? 



8'o X 7 = 56-0 -f- 100 = 0-56 pound. 



Working in this way, we find that the diet named 

 above has the following feeding value : 



1 This is a mixture of indefinite composition, often consisting of 

 equal quantities of bran and maize.
