contains about 30 per cent of digestible
protein. 6T.5 per cent of digestible car
bohydrates and Is per cent of digestible
fat. one hundred pounds of wheat bran
contain SOL pounds of digestible nu-
trients Every farmer is more or less
well supplied with the carbohydrates and
fat needed, while protein is relatively
scarce and high in price. Most rations
fed to live stock are if anything too low
in this very important and essential ele-
ment. and by reason of its greater cost
and scarcity it is generally not supplied
in ratiOns in a desirable amount. Ma
turally animals so fed are not abIe
TO perform as economically as those
which are fed balanced ration.
If we assign 10 protein a value of
cents a pound. and to carbohydrates and
fat a value of ! cent a pound, we find
that a ton of wheat bran, containing
1902 pounds of digestible nutrients,
would be worth $3.50 for feeding pur-
poses. 4 ton of wheat bran contains 1S4
pounds of digestible protein, which at 3
cents a pound would represent value
OF $3.50. 1t contains 1,4lS pounds OF
carbohydrates and fat, which at ! cent
a pound would represent $l4.lS. Corn
chops contain 60 per cent of digestlble
protein. 50 per cent of digestible car
bOhydrates and 3.5 per cent of digestible
fat, or a total of S3.S pounds of digesti-
BILE food per 100 pounds. There is an APP
parent discrepancysin the total amount
OF digestible nutrients in leo pounds
of the different materials referred 70 IN
this article This supposed difference
will be cleared up, however, if the reader
will bear in mind that in each Instance
the fat has been multiplied by 2.25,
thereby reducing il to its carbohydrate
equivalent. \ ton of corn chops contains
lbs pounds of digestible protein and
I.53S pounds of digestible carbohydrates
and fat The protein on the basis OF )
cents a pound is worth S4.14, and the car
bOhydrates and fat, $l5.3S.
oats contain 81 per cent of digestibie
protein, 5l.2 per cent of digestible car
bohydrates and 3.S per cent of diSestible
fat. or 7O.4 pounds of digestible matter
per 100 pounds. \ ton OF oats contains
Is4 pounds of digestible protein. worth
at ) cents a pound, $5.S2, and l,4oS
pounds of digestible carbohydrates and
fat worth S14OS, making its value per
ton, 1880.
Peanslts, with the hulls, contain about
2O.2, per cent of digestible protein, 10
per cent of digestible carbohydrates and
10 per cent OF digestible fat, or 5S1
pounds of digestible nutrients per 100
pounds. \ ton Of peanuts contains 4O4
mounds of digestible protein, which at
3 cents a pound is worth S12.12, and $40
pounds of carbohydrates and fat worth
$50. The nutrients in a ton OF pea
nuts ground with the bulls are therefore
worth S2O.22.
Choice cotton seed meal contains 81
per cent of digestible protein, Els per
cent of digestible carbohydrates and SO
per cent of digestible fat, or a total of
1872 pounds of digestible nutrients per
100 pounds. a ton of cotton seed meal
contains 740 pounds of digestible pro-
TEN, which at 3 cents pound repre-
sents a value of S22.2O, and S24 pounds of
digestible carbohydrates and fat, worth
SS.24. making the nutrients in a ton or
this material worth $3O.4i.
The figures presented do not take into
consideration the fertilizing value OF the
concentrates mentioned, which would OF
course, enhance the value of all of them,
but more particularly of cotton seeu
meal than of any of the other foodstuns
mentioned. 1t will be observed that the
figures presented in the case of all OF
these materials are lower than the price
one would have TO pay for ton OF
each in the open market at the present
time In fact, it is probably now nee
essary to pay cents a pound for digest
IDLE protein, and at least l.5 cents
sound for digestible carbohydrates and
fat In many concentrates such as
wheat bran, corn chop and oats now
largely purchased and fed often through
a misapprehensiOn of their real feeding
value, it would be necessary to pay :
cents a pound for carbohydrates and fat.
In the case of wheat bran, for instance
4 cents a pound for digestDle protein.
and cents a pound for digesJible fat
would make a ton of this material worth
s35.T2 or a price not far from what IL
now commands on the market The same
uz-ures applied to cotton seed meal, how
ever, would make the protein worth $50
and the carbohydrates and lat, $lt.4S'
or a total of $46.4S per ton. On any basis,
therefore, cotton seed meal holds its own
as cheap source Of digestible protein
ror the farmer. As matter of fact, If
We allowed only 3 cents a pound for
digestible protein in cotton seed meal
and ? cents for the carbohydrates and
fat available i'm any of the foodstufts
mentioned. cotton seed meal would then
sell at S3S IS per ton and supply protein
al one-fourth less cost than il can be
obtained through bran, corn shops, oats
or peanuts ground with the hulls.
These facts are cited and this expo
sftion Of the case has been made in the
hope Of enlightening many farmers ana
stock owners VINO are seeking a basis
On which to estimate the proper com
merciaI value OF the various fOodstuns
hey are using, and TO determine for their
own satisfaction which Will supply nu-
trients in the cheapest form and the
ones they should select for use as the
basal part of the rations they expect To
feed.
