Table II. AveraIge Digestibility of American Feeding Stuffs, with 

 Additions from the German Tables. 



The data of this table are mainly from digestion trials by Ameri- 

 can experiment stations, as compiled by Holland in the Massachusetts 

 (Hatch) Experiment Station Report for 1906. Coefficients from this 

 source are marked "M" in the last column of the table. To render 

 the table more complete, additions marked "L" have been made from 

 the German tables given in Llentzel and Lengerke's Landivirtschaft- 

 liche Kalender for 1908. Those marked "K" are from Zusammenset- 

 zung der Futtermittcl, Dietrich and Konig. Those unmarked are 

 from American stations, not reported by Holland.
