36 Report oF THE DEPARTMENT oF ANIMAL HUSBANDRY OF THE 
Class III. Contain 14 per ct. to 20 per ct. protein and 70 
per ct. to 75 per et. carbohydrates: Brans and middlings from 
wheat and rye and some proprietary mixed feeds. 
Class IV. Contain 8 per ct. to 14 per ct. protein and 75 per ct. 
to 85 per ct. carbohydrates: Cereal grains, cerealine, hominy 
and oat feeds, corn and oat chops, corn bran, corn germ feed and 
chop feed in general. Hays and fodders belong here more nearly 
than elsewhere. 
Samples of feed have been collected during the past two winters 
and analyzed chemically, physically and often microscopically. 
Cotton-seed meal should be light yellow, a dark color usually 
indicating inferiority. Protein may range from 42 per ct. to 
46 per ct. or more in good samples. Of 16 samples only two 
showed evidence of adulteration, but the price did not follow 
percentage of protein. 
Old, or pressure, process linseed meal and new, or naphtha ex- 
traction, process meal differ mainly in fat, the former containing 
three or four pounds more per hundred. Protein of new process 
meal is perhaps less digestible because of cooking. Nineteen 
samples were examined and all were good. One was somewhat 
low in protein with no sign of adulteration. 
Gluten meals consist mainly of hard or flinty portions of corn 
after bran, germ and part of the starch have been removed. They 
should contain at least 30 per ct. of protein to be classed as meals 
and may go to 40 per ct. ‘Two samples analyzed were good but 
the less nitrogenous sold for the higher price. 
The gluten feeds are a mixture of the meal with the bran and 
germs and are less rich in protein than the meals, ranging from 
18.8 per ct. to 28.1 per ct. This marked difference seems to be 
quite constant between the brands, samples of Joliet and Diamond 
brands running low. 
Malt sprouts are the dried shoots from germinated barley. But 
few samples were analyzed and these were found normal in com- 
position, with from 24.66 per ct. to 30.37 per ct. of protein.
