the heavier grain feeds. The proportion of the various 
nutrients is so well balanced that it is one of our safest feeds. 
It constitutes a portion of nearly every grain ration used by 
dairymen. The outer coverings of the wheat seed contain 
more nitrogen and less starch than the inner parts from which 
the flour is made. Wheat bran varies in protein from 12 to 
Ig per cent., averaging about 15.4 per cent. It is quite well 
digested by the ruminants, although samples tested by this 
Station were not as highly digestible as wheat middlings. 
Wheat Middlings.—This feed is supposed to consist of those 
coverings of the wheat seeds just beneath the hulls, including 
a small part of the darker colored flour, but the ‘‘fine’’ mid- 
dlings often include a considerable part of the flour. 
When but little flour is present the middlings contain more 
protein than does wheat bran. The better grades are also 
more digestible. ‘The presence of the flour does not add ma- 
terially to its value, as it favors the fattening of the animal. 
Owing to its fineness middlings can. be fed to better advantage 
mixed with wheat bran to add bulk. Wheat middlings con- 
tain from ro to 20 per cent. of protein, averaging 15.6 per cent. 
SEEDS OF LEGUMES. 
The only seeds of legumes that have been used to any con- 
siderable extent in feeding in this region are the Canada pea, 
the soy bean, and the cow pea. 
Canada pea meal is found in our feed markets only to a 
limited extent. It contains about 20 per cent. of protein and 
1 to 2 per cent. of fat. The peas are, however, quite exten- 
sively grown with oats for home use. The two crops can be 
grown, harvested, and fed together, and the mixed seeds make 
a much better feed than oats alone. 
‘Split Pea refuse’’ and “‘ Culled Peas.’—The former of 
these is a by-product from the split pea factories, and is made 
from the hulls, broken peas, and other refuse that is rejected 
from the peas used as food for man. ‘he meal made from 
this refuse has about 5 per cent. less protein than the regular 
pea meal. The smaller and more immature peas are also 
rejected by some manufacturers of split peas, and are sold to 
feeders as ‘‘culled peas.’’ Specimens of these immature peas 
which we have examined contain relatively more protein than
