This invention pertains‘ to improvements in under atmospheric or storage conditions. The
soya meal for feeding animals.
Boya meal is used extensively as feed for stock,
such as cattle, hogs, etc. This meal is a-product
5 resulting from removal of oil from the soy bean,
so-called. The oil may have been removed by
' an hydraulic press, or by an expeller, or by ex
traction with solvents: nevertheless the residual
meal has exhibited some undesirable eifects when
1° fed to stock. The meal has resulted in gas for
mation in the intestinal tract, and in faulty diges
tion and assimilation, and also in excessive hy
dration or looseness in the intestines of animals.
An object of this invention is to treat com
" inuted soya in general, and preferably to treat
soya meal, so as to avoid ?atulence in animals in
gesting this feed. A further object is to improve
the digestibility of soya meal and the assimila
tion of food values and generally to improve the
90 utilization of food in the alimentary tract of cat
proportion of moromi added tosoya meal need not
be large, about one tenth of one percent, though
greater amounts to several percent may be used.
when this complex composition is fed to cattle, 5
hogs and the like, it encounters in the intestinal
tract of the animals a condition of hydrogen ion
concentration of about pH 7.4. Under such hy
drogen ion concentration and at animal tempera
tures, this composition gradually is converted into 10
proteoses, peptones and aminoacids. Further,
absorption is facilitated of peptides and arnino
acids from the intestines, which is to say that
digestive efficiency or utilization of food values
is considerably enhanced.

Illustrative of preferred practice, though this
35 invention may be practiced otherwise, use is made
of the residue left from the production of soy
sauce, so-called. Soy sauce is manufactured by
fermenting a mixture of boiling soy beans, barley
or wheat, sodium chloride and water. Such pro‘

scribed in U. S. Department of Asrlculture Bulle
tin 1152 (1923) .
The soy sauce fermentation
lasts many months, during which are developed
of the appended claims.
What is claimed is:
1. An improved feed composition for animals,
comprising soya meal containing at least one of
the bacterial strains from the group consisting
of B.‘meeentericus,.n..sub?lisand B. vulgatus.
