The wastes of both steers were assumed to be only as digestible as 
cotton seed hulls, whereas their compositions show they were more 
digestible, thus throwing the error of the assumption, as in former 
experiments, on the side of diminishing the difference between the 
actual and calculated results. 
The digestibility of the combination of hulls and meal by Yellow 
Steer is below the calculated results for hulls and meal, and is the 
only exception in the entire series of digestions to the general rule 
of increased digestibility of the rations of hulls and meal over the 
results for hulls alone and meal as calculated. It would appear, by 
reference to the coefficients for Yellow Steer for this ration, in Table 
XXIX, that he was not up to his full digestive capacity during this 
trial,* as the coefficients for dry matter and all the nutrients for him 
are materially below those for Lineback, the duplicate steer on this 
ration, and, because of this, the mean coefficients for the two steers 
for the ration are probably lower than they should be. In evidence 
of the off condition of the Yellow Steer on this ration it will be 
observed that he digested almost up to the Lineback Steer in the 
next ration, 1 pound of meal to 4 pounds of hulls. In view of the 
above facts it would appear that the decreased digestibility of the 
combination was due to the animal rather than to the ration. 
The results for Lineback Steer show the combination of hulls and 
meal to be slightly more digestible than the calculated results for 
the same. 
13. DIGESTION OF A RATION OF COTTON-SEED HULLS 
AND MEAL 
By Steers, Lineback and Yellow. (1 lb. of Meal to 4 of Hulls.) 
.yf Date of Experiment, January and February, 1892. 
Rations fed—Lineback, 20 lbs hulls and 5 lbs. meal per day. 
“ —Yellow Steer, 18 “ “ 4-J “ “ 
Total period, 15 days. 
Feces collected, last 6 days. 
Samples for analysis were taken by putting an aliquot sample of 
food in an air-tight jar at each feed. 
Analytical and Other Data for Obtaining the Coefficients of Digesti¬ 
bility. See Tables XXXI and XXXII. 
* Yellow was slightly scoured for a few days during this period.
