Table 3. 



A study of table 3 will show the reader how radical a 

 change in the relation between albuminoids and non-albu- 

 minoids is brought about by so simple a change in foods as 

 the substitution of corn meal for gluten and cotton-seed meal. 

 The digestible albuminoids are reduced one third, while the 

 digestible non-albuminoids are slightly increased and the 

 nutritive ratio widened in consequence from i : 6.3 to i : 9.8. 

 The eflect of such a change in cows giving milk was shown 

 in a sharp falling otV in the yield of milk. To show how 

 great this shrinkage was, we will make a comparison with 

 the eight cows in groups i, 2, 4, and 5 : 



Daily average yield of eight cows in groups i, 3, 



4, and 5 during period 2 . . . .25.71 lbs. 



Daily average yield of eight cows in groups i, 3, 



4, and 5 during period 3 . . . . 24.73 lbs. 



Average shrinkage ..... .98 lbs. 



Daily average yield of two cows in group 3 dur- 

 ing period 3 ....... 31 -41 lbs. 



Daily average yield of two cows in group 3 dur- 

 ing period 3 . . . . . . . 26.98 lbs. 



Average shrinkage ..... 4-43 Ihs.
