out inodilieations of the ration as related to the protein content

THE NUTRITIVE RATIO. 



The effects of changes in the nutritive ratio, as a rule, of 

 course were directly in line with those evidenced by the groui)- 

 ings of the rations on the basis of protein content as related to 

 differing amounts of total organic nutrients. The unusual 

 amount of fat in a few foods caused considerable difference in 

 some of these relations of ratio to the actual amount of protein 

 in the ration. 



it is unnecessary to give all the data from the averages made 

 to show the general effect of changes in nutritive ratio. In con- 

 sidering the records on this basis they were grouped with rela- 

 tion to the ratio of 1:6, although the majority of the rations had 

 a wider ratio, principally because the standards in general call 

 for a ration with this nutritive ratio or one narrower. 



Moderate changes in the nutritive ratio within the ordinary 

 limits had considerable less effect on the milk flow than did 

 changes in the amount of total digestible organic matter. The 

 general results accompanying different modifications of the 

 ration which affected the nutritive ratio are stated on p. Go of 

 the general summary.
