To illustrate how these tables may be used, we will examine a 

 system of feeding which the writer observed the present season 

 in a certain section of the state, and was told was quite exten- 

 siv^ely practiced. The section referred to is devoted almost 

 exclusively to dairying, and timothy hay constitutes the greater 

 portion of the course fodder during the feeding season . Oats are 

 about the only grain grown . Corn is purchased and ground 

 with the oats, in about equal weights, to make " chop " which is 

 fed with the hay . The cows will not greatly vary from 1000 lbs. 

 live weight . While these cows are in full flow of milk in the 

 spring before pasture is ready, they are fed about 20 pounds of 

 hay and 8 pounds of chop per day. Turning to the tables we 

 find that 20 pounds of hay, 4 pounds of oats and 4 pounds of 

 corn contain digestible nutrients as follows : — 



20 lbs. hay. . . , 

 4 lbs. oats. . . 

 4 lbs. corn. .
