This table contains like data for the ration of roasted cotton¬ 
seed and silage, and for the roasted cotton-seed alone, that the pre¬ 
ceding one does for the ration of raw seed and silage, and for raw 
seed alone. Comparison of the digestibility of raw cotton-seed with 
that of roasted cotton-seed shows the dry matter of the roasted seed 
to be 10 per cent, less digestible, the protein 21 per cetit., albumi¬ 
noids 19 per cent., fats 15 per cent., and fiber 9.5 per cent., while the 
nitrogen-free extract is 1.7 per cent, more digestible in the roasted 
than in the raw seed. The analyses of raw and roasted seed reveal 
little difference in the composition of the two, beyond a slight 
increase in fat and fiber in roasted over raw seed, and a decrease in 
nitrogen-free extract. These experiments show a clear and heavy 
loss of digestible material from roasting, to say nothing of the 
increased cost of roasting the seed. 
8. DIGESTION OF RATION OF CORN SILAGE AND COT¬ 
TON-SEED MEAL 
By Goats. 
Date of Experiment, January and February, 1892. 
Daily ration, 2041.2 grams silage, equal to 72 ounces, and 170.1 
grams cotton-seed mea*!, equal to 6 ounces. 
Total peiiod, 14 days. 
Feces collected, last 6 days. 
Samples of silage were the same as given in digestion of silage by 
Brindle Cow. 
Cotton-seed meal was sampled by dropping a one-ounce sample 
of meal fed into a glass jar every time the feed was weighed out. 
The jar was kept tightly closed between the time of weighing. 
Analytical and Other Data for Obtaining the Coefficients of Digesti¬ 
bility. See Tables XV and XVI.
