Under average c,nditions a COW
yielding twenty-five pounds of milk
should have a ration composed of
/ about two-thirds roughage and one
third concentrates. By a number OF
| trial calculations we find that the re-
| quired nutrients are approximately
| obtained by selecting six pounds of
| wheat bran, four pounds of cottonseed
meal, eight pounds of corn stover and
forty pounds of corn siage. For greater
yields it is best, IS a rule, to increase
only the concentrates to meet the re-
quirements of the additional flow of
milk. thus making the proportion Of
concentrate to roughage greater tine
larger the yield o. milk.
The main part of the ration should
be supplied in two feeds, one in the
morning and the other in the late after
noon. 1t is desirable to feed some dry
roughage at noon, especially when thu
roughage in the morning and evening
consists of silage. The COW. on ac.
count of her large storeroom, the
large quantity of feed and therefore
does not require as many feeds as
some other farm animals.
Concentrates snd Roughaae.
As rule. it is best to feed the con.
centrates just previous to milking and
the roughage Immediately thereafter.
The grain helps to attract the cows to
their stalls. and by feeding the rough
age after milking we avoid tainting
the milk with undesirable odors when
the roughage contains these. When
corn silage. for example. is fed imme.
diately before or d.fring milking its
odor is always percepdble in the milk.
When fed after milling the odor is
never detected. 1t is Believed also that
feeding the concentrates by themselves
will result in more thorough mixing
of the saliva with then and thus in
crease their digestildlity. Further
more. a great deal Of dust can be
avoided by feeding the roughage after
milking, particularly when the rough
age consists of hay or dry fodder.
A prevailing opiuion that heavy con-
centrates will forIn an luxurious, pasty
mass in the cows sto1Rach does not

concentrates are sed directly before
milking and the roughage directly aft

An average COW IN full aow of milk
will consume forty pounds of corn
silage to good advantage. This amount
of si1age, combined with eight or tsn
pounds of dry fodder or hay, makes a
good combination Of roushage for
dairy cow. a@
Successful Feeding.
In the economical production of
milk it is absolutely essential to feed
cows according to their capacity. Just
what this productive capacity is can
be determined only by keeping care
full account of the feed consumed and
the milk and butter fat yielded by each
COW individually.
About half the nutriants called for in
a ration for an average mixer are
used to sustain the tody, go that it
will neither gain nor lose weight, the
other half being used to form milk.
Returns for feed can therefore be ex-
pected only from about so per cent of
the total nutrients required.
This means that a coy on q full ra
ton will yield practically twice as
much milk as she wSuld on three
fourths Of ration. Yet there are
thousands of dairymen who fail to
supply the last quarter Of a ration and
thus bring ruin upon themselves and
