90 AGRICULTURAL EXPERIMENT STATION. [Jan. 



Composition of English Hay and Vetch and Oats compared. 



Digestibility . 



The percentages of digestibility of the different ingredi- 

 ents in each of the above hays are the results of actual 

 estimations at this station. 



Coefficients of Digestibility. 



Pounds of Digestible Matter in 2,000 Pounds of the Perfectly 



Dry Hays. 



English hay, . 

 Vetch and oats, 



1,113 

 1,043 



It will thus be seen that the vetch and oats furnish very 

 nearly as much digestible matter in a ton as an extra quality 

 of hay. The digestible protein in the vetch and oats is fully 

 one per cent, higher than in the hay.
