When Bran Is Stored Without

Wheat bran undergoes degenerative
changes In storage which may be the
cause of serious disturbances when II
is fed to animals. The French chem
lists tMarchadi6f and Goujon) who
published the res6lts of their investi-
cations on this stbjeet in February
1914, state that when fresh bran IL
stored in large masses as il often Is in
warehouses. the center OF the, pile
heats and ferments.
During this heating process the pre-
tein compounds split up and a number
Of organic acids are formed, thu color
darkens and the odor of the bran
changes. The heat developed If q mass
Of several hundred tons OF bran Is
stacked three or four rnopths may rise
to point approaching spontaneous
combustion. A.
sours Under Pressure Il.
Under pressure and in the absence Of
air, as in the center Of stored pile or
stack, the bran Jumps and sours,
Hence caked and lumpy bran shouhi
always be an object Of SUSPICION. III
The chemists who made this investi.
cation state that the acidity Of normal
bran il OILS per cent. When the acid.
ity rises to 03 per cent the bran be
comes unfit for feed. At the, end OF
the fermentation process the acidity i
fifteen times greater than, In fresh
bran. HydroeYanic acid is one Of the
poisonous compounds, formed when
bran fernnents in, molasses under pres

Millers and dealers in feeds are eau
toned not to store fresh, bran in too
large piles. Complete ventilation pre-
vents the fermentive degeneration.
