fHERE are a great many perplexing
problems in poultry feeding.
They are made more perplexing
- the average poultry raiser by the ex-
plotting of various and sundry feeds,
tAe merits of which are based wholly
sn theoretical assumptions. We have
been insisting for number of years
upon one point more than any other in
poultry feeding, and that is that the
hen is a "meat eater The knowledge
of this fact has been of great impor
tance in poultry feeding, both fer egg
production and flesh production. In
creased production of eggs has been the
result in no small degree Of the feed
ing of animal foods. About every year
someone advocates or advertises a sub
stitute for animal food. Last year
great many letters came to us asking
if soy bean meal would take the place

ly advertised as substitute Various
other foods Of vegetable origin have at
one time or another been advertised to
take the place of animal food.
1t is well known that for heavy egg
production or for the growth of chicks,
there must be a considerable proper
tion of protein in tho foods; that is,
the ordinary grain foods such as wheat
and corn do not contain enough of the
protein elements. 1t is also known that
meat foods such as commercial beef
scrap, cut bones or any kind Of meat
foods with large proportion of the
lean meat, are very rich in protein.
Commercial beef scrap contains about
80 per cent protein. That is, about half
the weight o. the beef scrap is protein,
while wheat and corn contain some 10
to IL per cent protein.
Inaccurate Claims Made.
1t was first a question whether
sufficient amount of protein in the
ration, irrespective of its source, was
not all that was necessary, or whether
such foods as beans, peas, linseed meal,
gluten meal or cotton seed meal, that
are rich in protein, would not give as
good results as the protein found in the
meat foods. Many to this day claim
that this is all that is necessary in face
of the fact that it has been thorough
ly demonstrated by experiment that
animal foods must be fed to poultry in
order to get good results whether in
egg yield or meat production. A num-
Der of experiment stations during the
last ten or twelve years have conduct
ed careful experiments on this point
and the results have invariably shown
that vegetable protens will not take
the place of animal protens.
The latest experiment on this point
was made at the New Jersey Station,
the results of which have just been
published. Ia this experiment it was
found that animal food was necessary
not only for the growing chick and for
the broiler but for the laying fowl. A
poultry food, Hen-e-ta, which has been
extensively advertised during the last
few years as complete ration for
fowls, but which contains no animal
feod, was made the subject of a com
parison in New Jersey experiments,
with result wholly unfavorable to the
claims made for this food.
Theory vs.. Fact.
Not only was 1t claimed for this food
that NO animal food was required and
that it contained enough protein from
other sources, which was all that wa.
required, but the claim was also made
that the phosphorus or bone making
material was as efficient when obtain
cd from inorganic or mineral sources
suoh as phosphate rock, as the samt
constituents obtained from anima
sources, such as ground bone. The ex
periments showed very clearly thai
"phoPhorie acid from an organic
source (anJnal bone) is much more eff
ficient than phosphoric acid from al
inorganic source phosphate rock Of
