Fceda and Feeding. 



Table III, Average Digestible Nutrients and Fertilizing Constituents 

 IN American Feeding Stuffs. 



Tlie data for the digestible nutrients in this table are derived, for 

 the most part, by combining the data in the two preceding tables. 

 Where no digestion factors are available in Table II for a given 

 feed, the digestion factor of a similar feed has been used and that 

 fact indicated by an asterisk. 



The fertilizing constituents given are mostly from the extensive 

 tables compiled by Roberts in The Fertility of the Land, and by 

 Voorhees in Forage Crops.
