SOME EXPERIMF nFINTEREST
TO DAI y IN.
The Use OfCotton Il Meal in the
Dairy Ration, and Its Influence
Upon the Dreaming of Milk.

In bulletin No. IA of the Texas Ex-
pertinent station college Station P. o.
is reported a series of experiments
made TO determine the influence of
cotton-seed meal in the dairy ra-
ton on the creaming of milk, both by
the common or gravity method and the
centrifugal method
In these experiments cows were test
ed in lots containing several cows each,
the cows in the contrasted lots being
in as uniform a condition with respect
to milk flow, time from calving, &C., as
it was possible to arrange them. The
feed for each pair of cOntrasted lots
was the same. except that one lot re-
ceived equal parts corn meal and bran
as bye food, while the other lot had
cotton-seed meal and bran in equal
parts.
~ In the case of two lots of five cows
each that We're far advanced in milk
200 to 124 days on the average) it was
found that where the cream was raised
by gravity at the ordinary summer
temperature, the milk being set at
about 10 degrees in Fairlamb cans and
skinned when sour lin II to "a hours. J
an average oflS.4 pounds of butter
was lost in the skim milk of the cows
fed on cotton-seed meal, for every 100
pounds present in the milk set, as
against 30.9 pounds lost when no cot
ton-seed or cotton-seed meal was fed.
In the case of two lots of four cows
each, less advanced in milk, (SS to SO
days. the loss of butter fat in the skim
milk on the cotton-seed meal ration
was 1921 pounds out of every 100
pounds actually present in the original
milk, against 81 8pounds lost when no
cotton-seed meal was used.
In the case of two lots of three cows
each that averaged but fifty days from
calving at the beginning of the test, the
loss was 11.3 pounds on cotton-seed
meal ration, against 14.9 pounds when
no cottOn-seed was fed.
The average loss on cotton-seed meal
for ordinary setting was therefore lie
pounds out ofevery 100 pounds present
in the original milk, against 25,e
pounds lost when no cotton-seed meal
was fed.
Where the milk of five cows, 152 days
from calving, was set at a temperature
of As degrees and kept at this tempera-
ture with ice for "a hours and then
skinned, the loss was 376 pounds out
of every 100 in the original milk, the
cows having no cOttOn-seed meal;
while five cows, 1872 days from calving
and having cotton-seed meal, lost but
22.9 pounds out of every 100. When
the milk was kept only 12 hours before
skimming the loss without cotton-seeO
meal was 49.1 pounds, against 81
pounds lost with cotton-seed meal
showing a decided advantage in the
longer setting.
When the cream was extracted by
the centrifugal method as soon as
MIXED, that from four cows; 210 days
from calving, showed loss of but | &
pounds without cotton-seed, and tha
from four cows, I'll days from calving
but 23 pounds with cotton seed meal
That from four cows, 62 days from
calving and having no cotton seed los
3.27 pounds, and that from four cows
5S days from calving and having cottor
seed, lost 33 pounds out of every hun
dred actually present in the whole
milk.
These results show that in the case o
centrifugal creaming very much larg
er per cent of the butter fat present il
the milk is obtained, and that withou
regard to the character of the feed useC
whereas in ordinary gravity creaminl
the character of the food may have ;
very marked influence upon the guam
tity of butter obtained from the milk.
