In this table tlie masimura and minimum amount digested of each 

 constituent in various experiments are given, together with the probable 

 mean. How much we may depend on these determinations for our 

 American fodders is doubtful. They serve, however, to show in wJiat 

 direction we must work, and what assistance chemistry can render tbe 

 farmer. 



To show how these tables are used in connection with fodder analyses 

 an example may serve. A farmer has a milch cow \»,'hich he wishes to 

 feed in the most economical manner on the fodder at his disposal, com- 

 bined with other food purchased, and with a view of obtaining the best 

 return in milk. It has been found that a milch cow requires, as a daily 

 ration, for every 1,000 pounds live weight, according to Kiihn —

The farmer has an average (German) hay and mangolds, which, if fed 

 together, would make a ration too rich in carbohydrates. Taking into 

 consideration his ability to purchase, he finds from the analyses, digesti- 

 bility and fodder value, that he can make this up in the best way by 

 buying cotton-seed meal and constituting tlie ration as follows:
