south IL becomes necessary at some sea-
son OF the year TO purchase additional
concentrates. Just what to buy and
how to buy 1t is a matter of great i'm
portance to the farmer. In purchasing
a foodstuff several things should be TAX
en- into careful consideration. First Of
all, the market should be canvassed for
material suited to the class and condi-
ton of stock TO which 1t is to be
fed: second, the market price should be
taken under advisement; third, the nu-
tritive value should be carefully investi-
gated; fourth, the percentage Of plant
food which the concentrate contains is an
important matter to understand as will
be shown later; fifth, the relative percen-
taees Of the different digestible nutrients
should be ascertained.
A foodstuff ordinarily contains four
things which are Of Importance to the
farmer; namely. dry matter. digesuole
protein, digestible Carbohydrates, ana Oh
gestible fat The word disestiple -
used advisedly, for no matter what per
centage of a given element q IoousIuAA
may contain, the only part which Is OF
Importance in the animal economy is that
which man be digested and taken up oy
the system for the nourishment and de-
velopment Of the animal body. II is rare
Iy il ever a difficult matter 70 supply
a sufficient amount of dry matter TO an
animal since there is an abundance OF
roughness on most farms containing
plentiful supply OF material Of this char
acter. One may regard this element
therefore, largely as negligible guam
tity in purchasing concentrate. WIN
ditiou Is entirely different. This Is the
element which is chiefly useful IN oulld-
ing up nerves and tissues. 1t Is neces-
sary to the proper nourishment OF every
class of animals no matter what the age
or condition may be. 1t is the element
which the farmers find most difficult IN
securing in a plentiful supply. 1t is rel
atively the most costly Of all the eie-
ments to purchase or produce on the
farm. Therefore, it is matter Whicn
should receive attention In the puE-
chase OF a foodstuff. CaroonyoraIes
are relatively not so important They are
concerned in building the fire, as it were,
under the boiler in heating up the sys-
tenn and supplying it with energy. Ihey
are relatively abundant in most con-
centrates and produced in large QuantV
in virtually all fGSms of roughness rals-
ed on the average farm. Fat Is a mere
expensive element to obtain than caroo-
hydrates. 1t is also important In amman
nutrition 1t may take the place OF car
hydrates, and in fact, is useful not only
in producing body fat, but chiefy as =
source of heat and energy. These are the
main factors to bear IN mlno III puE-
chasing a concentrate.
While. there Is q great variety OF 1000
stuffs on the market. only few stand
ard materials can be considered az TINS
time. In fact, they constitute the chlel
source of supply from which concen-
frates must ordinarily be purchased by
the southern farmer. They are corn corn
and cob meal, corn bran, wheat pran'
wheat middlings, rice brans oats and cot
ton seed meal
A glance at the table shows that they
do not vary widely In content Oh uLs
matter. with regard to the protein
/ however. the difference is very marked.
varying from a. per cent with corn ana
cob meal to 37.2 per cent with cotton seeo
meal. Bran contains less than one-tnlru
! as much protein as cotton SEED meal
and oats only one-fourth as much. The
statements made with reference to pro-
TEN indicate why cotton seed meal De-
comes such a desirable concentrate on
the southern farm, and why its pur-
/ chase to combine with other foodstuns
/ CONSTITUTES SUCH 6ON0 RAe~~~N~Ns
first place, relatively speaking, ~ is
cheaper per ton than any Of the other
materials mentioned, and If 1t contains
| from three to four times as much pro-
TEN as most of them 1t is by all odds
the best thing to purchase. With hign
priced corn, it will often pay to grind
il into corn, cob and shuck meal There
are mills now on the market which wall
do the work admirably. This would make
hTHf W
properly supplemented with cotton seed
meal. il furnishes an admirable mixture
70 feed to horses, mules and cattle. In
carbohydrates cotton seed meal Is low
as compared with corn. This, Of course
is a very important matter, for the two
viii thus combine without increasing
the percentage of carbohydrates unduly
while increasing the protein content. In
fat cotton seed meal Is relatively high
containing from two to four lines as
much fat as m~st OF the foodstuffs men,
toned. Since fat Is readily converted In
IN energy and furnishes two and a
quarter times as much energy per pound
as carbohydrates cotton seed meal Il
valuable as a source OF heat and energy
From these statements II Is readily ap-
parent that as a source OF protein the
meal stands unrivalied, and while II
NAV be fed to many classes of live
stock without con- bination with Other
foodstuffs, Il appears that 1t combines
admirably with those which are cheapest
and most easily obtained on the aveFagt
| farm.
Attentio has already been called t.
the importance OF considering the
amount OF plant food a ton Of any con
centrate may contain. The following ia
BILE shows the pounds of plant food
per ton contained in the several food
stuffs under discussions:
