for milch cows. The suggested ration B does not contain oats. 
Chicago gluten meal contains® a great deal of protein, and it 
would not be wise to change at once animals which had not been 
receiving gluten meal, to a ration containing as much gluten 
meal as ration B. All changes of feeds should be made gradu- 
ally, so that the animal may become accustomed to the new ration 
without derangement. Ration C is heavier in grain than either 
B or A. It will be observed that both the rations B and C con- 
tain the weights of protein called for by the suggested standard, 
and that the fuel value of B isa little greater and that of Ca 
little less than the standard calls for. Ration C is five cents 
and ration B seven cents cheaper than ration A. If ration A 
were reduced one-ninth, it would give a fairly well-balanced 
ration of about the proper size and its cost would be reduced to . 
24 cents. B and C would then be respectively two and four 
cents cheaper than A.

Ration No, 3, as fed, contained about three pounds of digest- 
ible protein, and nearly 38,000 calories of energy. The ration 
was about one-sixth larger than called for by the tentatively sug- 
gested standard. The ration contained a very large amount 
(4.1 pounds) of cotton seed meal. Buffalo gluten feed is not 
as rich in protein as is either Chicago gluten meal or cream 
gluten. Still the cotton seed meal and the: Buffalo gluten, 
taken together furnish two-thirds of the protein which would be 
called for by the standard. Hominy meal differs but little from 
corn meal in its composition. It contains about the same per- 
centage of protein as corn meal, and more of fat and less of
