the udder after the regular milking
was finished (Hegelund method): where
the regular mixer did not milk clean,
the gain Obtained by clean milking to-
gether with manipulation OF the uddar
was ascectained. The plan of the eS
periments was therefore such as TIC
show the character of the work done
by the different mixers.
20 La our university herd the aver
age daily production of milk from
twenty-four COWS was increased as per
cent by means of the manipulation
method and the production of fat was
increased by 90 per cent orange 80 to
80 per cent for individual cows) as
the result of milking experiment con-
tinued for four weeks; the average
gain in milk being l pound and in fat
.O9 pound per head per day.
80. A similar average increase in
production was obtained for the twelve
dairy herds tested, viz, a gain of LOS
pounds in the daily production of milk
per COW and Il pound OF fat. The re-
suits obtained in this investigation,
extending over period of four months,
with cows in all stages of lactation.
indicate that this gain is maintained
through the whole period of lactation.
An increase in the daily production of
butter fat per COW, of one-tenth of a
pound, for the million cows in the state
would mean an annual gain OF 30,000,-
600 pounds of butter fat if the COWS
give milk eco days in the year; the
value of this increase to the dairy in
dustry OF the state would be about
$4,000, 900, on basis of valuation of
20 cents pound for butter fat, fig
ure considerably below average Elgin
prices.
"4 The largest amount of milk OBJ
tanned from COW by the manipulation
method, after the regular milking was
done, was 5 pounds per day and the
lowest 30 pounds. The corresponding
figures for fat production was ga and
.02 pound. The former figure is con-
siderably above the average total daily
production of cows in this or other
states.
So The greater portion OF the gains
obtained came through lack of care on
the part of the regular mixer as the
COWS were not milked perfectly clean.
But even in herds where the mixers
did their work we'll there we're always
one or more cows which gave an in
crease Of nearly pound of milk aud
one-1enth of a pound of butter fat by
the manipulation method.
"6. The milk obtained by the manip-
ulation method is similar in compost
ton to that of strippings:" on the
average for all herds 1t contained 1882
per cent fat aud was found to be about
two and one-half times richer than the
ordinary milk. The highest per cent
of fat found in the after milking from
any one COW was % per cent, and from
any herd l4.4l per cent.
ST. The difference in the work done
by different mixers is brought out
strongly by the results of the work
done. In several cases one mixer did
his work so much better than the
others in che same herd as to be worth
nearly $40 per month more to the
owner on account of the larger yields
of milk and fat which he obtained from
the COWS MIXED by him.
So The results Obtained in this in
vestigatiOn suggest that a thorough
system of milking is a foundation re.
quirement III successful dairying.
For. aside from directly increasing
the production of milk and fat from
the cows, exhaustive milking will be
likely to maintain maximum flow OF
milk through the lactation period
and to permanently develop the dairy
qualities of both the dam and her off.

Especially notice the 9Th, from
which it appears that the farmers Of
Wisconsin would get S6,000,0OO more
per wear for their milk if they adopted
and practiced this new idea. Notice
also the 18th, by which it appears that
a hired hand who is on to this new
kink is worth about $40 per month
more to the farmer because he knows
how to get cream out of the COW after
she has been MIXED dry. Solomon

nothing new under the sun, but he die

The farmer who does not take first

these new things as they are discovered
will soon be back number.
