communication with the pens where
- SD ones are kept. If others take
sick the well ones should be moved
again as 1t will do little good to move
out the sick ones and leave the others
to take the diseases in the infected
pen. washings from infected lots
when carried into streams will spread
the disease to farms located further
down the streams and hog raisers
should be especially careful of their
water supply when the disease is in
their locality. They should not allow
hogs to take water from a stream when
the disease is known to be on farms
above them.
There has been a great deal of work
done to find some cure or preventa-
tive for hog cholera. Certain lines
of work seem to indicate that sys-
tenn of vaccination may be perfected
that will act in a similar manner on
hogs as a means of preventing hog
cholera. as vaccination does on cat
tie to prevent blackleg. If such a
method is found to be reliable the dis
ease will be practically under con-
troll. The feeding and care that hogs
receive will do much to prevent such
diseases as unthrifty herds are the

ease. Plenty of green feed such as
cane. alfalfa, ETC., with a good supply
OF fresh, clean water during the sum-
mer months will do a great deal to-
ward keeping hogs in the best posi-
BILE condition.
The Oklahoma experiment station
at saltwater, has devoted considera-
BILE time to the study of hog cholera
and the transmission of the disease
by means of the hog cholera bacillus
This work has been principally along
the lines OF producing immunity in the
small experimental animals and study
ing the effect Of the germ in the hog.
Revinsed Feeding Standards for Cows
i'm Milk.
Hoards Dairyman.
We long ago repudiated the SOCIAL
ed German (Wolff) feeding standard
for milch cows, with it's inflexible re-
| duirment of rs pounds of indigestible
protein and a nutritive ratio of / part
digestible protein to 81 parts carbo-
hydrates, and we are but little better
pleased with the Wolff Lehman
| standards. although the latter recog-
nize to a degree the fact that the
amount of milk yielded should be con-
| sidered.
We are not so situated as to make
| careful conducted experiments practi-
cable, but observations in our own
| herds indicated that there was a rich
| field here for experiment station work.
| For example, II a COW Weighing 1000
pounds, requires z of a pound of diges-
| tible protein for daily maintenance and
| yields 30 pounds of per cent milk
containing approximately one pound
of protein in the form of casein and
a tFnA A-r1
what became of the remaining of a
pound of digestible protein, or falling
in that tell how much protein was act
| ually needed to enable such a COW to
| produce that or any other amount of
milk.
Prof VOL. OF the Wisconsin Station,
made an attempt to solve this problem
| by getting the average ration fed by
successful dairyman in Wisconsin and
| elsewhere. AS might have bee1 ex-
pected, there was very little hsifor-
nifty in the reports received, but after
a careful study of the figures he pro-
| posed an American standard of %
pounds digestible protein, 1873 pounds
| fat.
| This was a long step in the right
direction. but 1t could hardly be called
| a scientific conclusion, because it had
no deflnate, well-ascertained figures
upon which to rest, and we continued
to clamor for more light. We confess
| that the answer to our demand has
been very slow In coming and that the
great majority of Experiment Stations
i'm fact all but three or four-have
preferred apparently to accept the
German standards and plod along in
old ruts, rather than undertake orig
| inal research work in this direction.
Indeed, only one Station has set it.
self strenuously at the problem of UNI
dertaking through a succession OF
years to ascertain the exact relation
of food consumed to milk produced
We refer, of course, to the Minnesota
Station, where the powers in control
have permitted Prof. Hacker to study
| and experiment on milk problems
This work has been going on for near
ly or quite nine years nos, and al
though a mass of valuable data has not
been reached. Like every careful ex-
pertinent, Prof. Hacker makes haste
slowly, and does not jump at conclus-
ion.
He has published three bulletins re-
porting progress, the last one in the
early summer of the present year. and
from 1T we compile the folliwing table
