Digestible nutrients for 1 lb. milk solids. 



The results of this experiment furnish no testimony in favor of 

 the superior quality of Ration No. 1, i. e., in favor of the ration 

 containing the larger proportion of easily digestible carbohy- 

 drates that belong to the hexose group. 



The evidence, if literally applied, shows Ration No. 2 to be even 

 the better one. The daily production of milk solids was essentially 

 the same with the two rations, viz. : 2.74 lbs., but the daily con- 

 sumption of digestible nutrients was greater with Ration No. 1, 

 the respective quantities being 15.3 lbs. and 14.1 lbs. and the 

 amounts of digestible material eatcu for each pound of milk solids 

 produced were 5.56 lbs. and 5.15 lbs. If, therefoTe, a certain 

 class of carbohydrate compounds possesses a superior nutritive: 

 value the fact must be brought to light through some method of 

 investigation more searching than feeding experiments of this 

 character. 



This experiment does bear testimony concerning one matter of 

 considerable impoirtance. It is certainly clearly shown that in 

 one case at least, the commercial feeding stuffs of the by-product 

 class were successfully substituted for such grains of high quality 

 as oats and peas.
