AVERAGE PERCENTAGE COMPOSITION OP ALFALFA AND OTHER 

 FORAGE CROPS.*

AVERAGE PERCENTAGE OF DIGESTIBILITY OF ALFALFA AND OTHER 



FORAGE CROPS. 

 (Experiments with ruminants.) 



DIGESTIBLE NUTRIENTS IN ALFALFA AND OTHER FORAGE CROPS. 



The following table indicates the actual feeding value of 

 eight different kinds of feed, based on the amount of digestible 

 nutrients contained in them. These values are calculated from 

 the figures given in the table just preceding. The values per 

 pound assigned as the basis of calculation are protein, $0.0674; 

 carbohydrates (starches, etc), $0.0064; ether extract (fats), 

 $0.0112. These figures are merely relative, as the prices of the
