The ration now corresponds as closely to the standard as 

 could be reasonably expected in practice. It must not be 

 understood, however, that this is the best or only combina- 

 tion of feeds which a 900-pound cow giving 10 quarts of 

 milk daily, should receive. It is only one combination 

 which meets the requirements of the standard, and for 

 convenience in some following calculations, we will call it 

 sample ration No. 1. 



Any other ration can be worked out in exactly the same 

 manner as the preceding, and in order for the reader to 

 familiarize himself with the process it is suggested that he 

 work out sample ration No. 1 independently and then com- 

 pare his results with those given. Most feeders can make 

 pretty close estimates of the live weights of cattle, but in 

 order to aid them in this if no scales are available, a table 

 based on girth measurement is given on the following page. 



TO MAKE UP A RATION. 



Take 1 to 1% psr cent, of live weight for the amount of 

 hay and about 4 per cent, of the live weight for the amount 

 of silage, and in any case enough fodders or roughage to 

 make up about two thirds of the dry matter. Using some 

 of the common coarse feeds which the average farmer is 

 likely to have on hand we will make up some ' ' foundation ' ' 

 rations for a 900-pound cow, and from Table III calculate 

 what they contain.
