Brewer’s grains are the barley grains from which the starch has 
been removed by growth and fermentation. In fresh state they 
contain too much water to justify paying a very large price. 
Dried they furnish about as much protein as the malt sprouts. 
Buckwheat middlings and other buckwheat products were 
found of good quality, but varied widely in protein content, the 
iniddlings and feed running from 24.8 per ct. to 33.7 per ct., 
while the single sample of “ ships” 
9.2 per ct. fat. 
Wheat brans were found pure, but not constant in composition, 
showed 33.75 per ct. protein, 
the protein ranging from 13.4 per ct. to 17.1 per ct., and the. 
starch from 17.5 per ct. to 30.6 per ct. 
The mixed wheat feeds are combinations of the offals of wheat 
milling and showed only the natural variations. 
Wheat middlings, with one exception, proved normal in com- 
position showing only variations similar to bran and due to same 
cause, difference in milling processes. Middlings contain more 
protein, more starch, a little more fat and less fiber than bran and 
are more digestible. It would seem that preference should not 
be given the bran as a feed. 
Hominy feed or hominy chop consists of the hull, germ and 
part of the starch of corn grains; and contains less starch, about 
the same amount of protein and more fiber and fat than corn meal. 
The samples analyzed appeared quite uniform in composition, 
- except Hudnut’s which contained seven per ct. more protein than 
the average. The average was about 10.5 per ct. protein, 46 
per ct. starch and sugar and 7.75 per ct. fat. The prices were 
much less uniform than the percentages. 
In mixed feeds seems to lie the greatest danger from adultera- 
tion, a danger which is not entirely guarded against by chemical 
determination of protein and fat. Oat hulls are extensively used 
as adulterants in foods of this class. Prices were often equal to 
what would have bought whole corn and oats. In 26 cases out of 
35 examined, the fiber content is larger than the average for whole
