fed in previous experiments of a similar nature.^ The present 

 normal ration differed, however, somewhat from the former, as 

 will be seen from the following statement : — 



The digestion coefficients evidently would be somewhat higher 

 for the present normal ration, and hence the total digestible 

 nutrients contained in the present average daily ration would 

 be rather in excess of those given. The data presented, however, 

 are at least comparative ; in fact, the exact amount of digestible 

 nutrients contained in the rations has no direct bearing on the 

 objects sought; they simply indicate that the two herds were 

 sufficiently and normally nourished." 



In the second period Herd 11. consumed about l/o pound 

 more digestible protein than Herd L, due to the presence of 

 the soy bean meal. In the third period Herd II. ate some .0 

 of a pound more fat (derived from soy bean oil) than did 

 Herd I.

3 It was not considered of sullicient importance to malse an actual digestion trial with 

 the normal ration; neither were all the feed stuffs entering Into its composition completely 

 analyzed, hence average coellicients of the individual concentrates could not be employed.
