A STUDY OF RATIONS FED TO MILCH COWS, fps 
Ration No. 9 is quite small, as estimated by its fuel value, and 
it is also deficient in protein. Its nutritive ratio is quite large 
(6.4). The use of more rowen and stover in ration B, with 
more corn meal and about the same quantities of bran and other 
nitrogenous feeds as in A, gives a larger and better balanced 
ration for the same cost. The use of larger quantities of rowen 
in C, with a corresponding decrease in the quantity of grains 
fed, gives a well balanced ration of about the proper size for 20 
cents. ‘The value of rowen and of clover in particular as a feed 
is pointed out in both these rations and in ration No. 10, where 
by using 15 or 16 pounds of rowen with stover and a compara- 
tively small quantity of grain, a complete ration is furnished for 
20 cents per 1000 pounds live weight.

Ration No. to, as fed, differs from 9 only in being a little 
larger. Practically the same suggested changes are made for 
this ration as for No. 9g, only as gluten meal was not used in 
No. 10, the quantities of cotton seed and wheat bran are cor- 
respondingly increased. Ration B of No. ro and ration C 
of No. 9 are among the least expensive of the suggested 
rations. 
Ration No. 11 (see next page), as fed, was a well balanced 
ration, but was larger than probably needed. ‘The two suggested 
rations, B and C, are alike so far as their digestible protein, 
fuel value and nutritive ratio are concerned. ‘The grain mix- 
tures and coarse foods of the two are, however, quite different. 
Ration B, which uses oat hay instead of merchantable hay, is 
four cents cheaper than C.
