In the preceding experiment a ration of 12, pounds corn silage to 
1 pound cotton-seed meal, having a nutritive ratio of 1 to 6 29, was 
fed. The ration in this experiment w T as 8 pounds corn silage to 1 
pound cotton seed meal, having a nutritive ratio of 1 to 4.98. The 
coefficients of digestibility of the latter ration, as would be expected, 
are much higher than those of the former, and the results presented 
in the tables below, like those for the former ration, are still more 
marked and interesting.
