36 N. C. AGRICULTURAL EXPERIMENT STATION. 
Digestions of cotton-seed hulls have been made with four animals, 
two cows and two goats. The total protein digested by the Goats 
and BrindleCow is much below that digested by Belle of Brookside,tbe 
amount excreted in dung by Gray Goat and Brindle Cow being more 
than what was consumed. This is most likely due to bile com¬ 
pounds, mucus, and other intestinal products not belonging to the 
undigested food residue proper. Extraction of the feces with ether, 
alcohol, hot water, and cold lime water* failed to lower the nitrogen 
in them. The coefficients for dry matter and nutrients other than 
protein make a first-rate showing for cotton-seed hulls. A low pro¬ 
tein coefficient would be expected in a coarse fodder having so wide 
a nutritive ratio. 
11. DIGESTION OF RATION OF^COTTON-SEED HULLS 
AND COTTON-SEED MEAL 
By Belle of BROOKSiDEf (1 lb. of Meal to 7 lbs. of Hulls). 
Date of Experiment, December and January, 1890-’l. 
Ration fed, 3 pounds of cotton-seed meal and 21 pounds of hulls 
per day. 
Total period, 13 days. 
Feces collected, last 4 days. 
Samples for analysis were taken from each feed and enclosed in 
air-tight jars till end of experiment, then ground and mixed. 
Analytical and Other Data for Obtaining the Coefficients of Digesti¬ 
bility. See Table XXVI.
