close to the standard. The nutritive ratio very closely 

 approximates the standard nutritive ratio. 



At the market prices the new ration will cost: 



2 Ibs. cotton seed meal $ . 026 



7 Ibs. corn and cob meal 077 



8 Ibs. wheat bran 100 



12 Ibs. crab grass hay 090 



Total cost per ration $.293 



In other words this ration will cost John Smith 

 $0.293 P er day P er horse. The ration of John 

 Smith's costs $0.361 per day per horse. This new 

 ration will save Jcrhn Smith $0.361 $0.293= $0.068 

 per day per horse. On fifteen horses the saving will 

 be 15 x $.068 = $1.02 per day. In a year the saving 

 will amount to 365 x $1.02 = $372.30. This exam- 

 ple just cited is not exceptional. There are many 

 farmers, livery men and others who are throwing away 

 money every day on their feed bills, and still they are 

 not always getting the best returns. This second ra- 

 tion, as it more closely approximates the standard, is 

 indeed a better one, besides being cheaper. 



EXERCISE. Learn from your people or some acquaintance the 

 rations used. Select one of these rations ; find out the cost of the 

 feeds that are used and try to substitute some other feeds to reduce 

 the cost of the ration. Is the ration you figured out better than the 

 original one ? What is the saving in your ration ?

 meal are some of the more concentrated feed stuffs 

 which are fed to horses and mules. The roughage
