The above table is taken from Technical Bulletin No. 3, with the 
exception of the columns for sugars, starch, and undetermined 
carbohydrates, which have been added. The ration of 1 pound of 
cotton-seed meal to 7 pounds of hull's was fed to Belle of Brookside 
immediately after completing the experiment on the digestfcn of 
cotton-seed hulls with her, and is inserted here as being of interest 
in connection with the series of rations of cotton-seed meal and hulls. 
In the following table (XNVII) are presented the same data for 
this ration that the preceding ones contain for the rations of meal 
and silage.

The cotton seed hulls were given the same coefficients of digesti¬ 
bility in this ration as were found in the experiment with this animal, 
as they were thought to be more nearly correct for her, while in the 
remaining rations the mean coefficients of the four experiments 
have been used. 
The results here, in harmony with those in the rations of silage 
and meal, show the combination to be, on the whole, slightly more 
digestible than hulls alone and meal in the rations from which its 
coefficients were obtained. The nutritive ratio of this ration is 
quite wide (1 to 10.8), and the decrease in digestible protein consid¬ 
erable, but this is more than compensated for in the increase of 
digestible carbohydrates. ^ 
The digestibility of the dry matter of cotton-seed meal as obtained 
from this ration is above 100, the protein and the fat less digestible
