Some mouths ago a New York
man boosted about his ability to put
butter fat into the milk of cows by
feeding them tallow, Hoard's Dairy
man published the letter about it at
the time, and now refers to the
subject again. 1t says that four
dairy cows were selected for the OK
pertinent, and by gradual additions
they we're brought to eat two
pounds OF clean beef tallow each,
daily, in addition to the former ra-
ton, consisting of forty pounds OF
ensilage, with hay at noon, and six
pounds of a mixture of two parts
wheat bran and one part each OF
cotton seed meal and corn meal.
The skim milk was also fed back to
the COWS. The COWS were given
churn test before commencing the
feeding of the tallow, and similar
test the fifth week thereafter. Cow
No. l showed an increase of 43 per
cent, in butter yield; COW No. 2, 46
per cent; COW No. 3, SO per cent;
COW No. 4, 30 per cent
Before the feeding of fat COM
lnenced it required fraction over
% pounds of milk to make a pound
Of butter, aud at the second test
only 18l pounds.
In discussing this experiment
Hodrd's DGiryman said:
owe are more emboldened to ask
for suspension of fiual Judgement
10 the case, because OF the fact that
a somewhat similar experiment was
tried at the New Hampshire Agri-
cultural Experiment Station, and
reported in full in it's bulletin No. 20
March, 1894. In the course of
that experiment cotton seed oil,
corn oil, palm oil, cocoanut oil, olee
oil, and stearin were fed, and each
for period of about fifteen days,
but only three kinds of oil to any
one COW. The results are summa-
rized as follows by Prof. A III.
Wood:
"'Now, in conclusion, l think that
may say that this experiment
indicates:
"'That the first effect of an in
crease of fat in cows ration is to
increase the per cent. of fat in her
milk.
"'That with the continuance of
such ration, the tendency is for
the milk to return to its normal
condition.
That the increase in fat is not
due to the oils, but to the unnatural
character of the ration.
"'That the results in this expert
nent tend to confirm the conclu-
sions expressed in previous bulletins
from this station, that the compost
ton of a cows milk is determined
by the individuality of the COW, and
that although an unusual food may
disturb for time the compositions
OF the milk, its effect is continuous
at is, perhaps, unnecessary to
say that we have not received any
report of the results of the second
experiment, if one was made, but in
lieu thereof we are in receipt of
Bulletin 81 (May, 1885 of Cornell
University Experiment Station, Civ
ing the full details Of a similar ex-
pertinent carried on at that station
last fall under the direction OF Prof.
Wing. Not only was Prof. Wing
unable to obtain such extraordinary
results as Mr.. Van Dresser reported,
but there was not even the temper
airy increase reported from New
Hampshire, In some cases Prof.
Wing noted slight increase in fat
and in others decrease, but there
was the rather abnormal result that
| two months after the close of the
experiment and the withdrawal of
the pure fat from the ration, all the
COWS, except one, We're still giving
practically the same amount of
milk of the same quality, and that
one had practically reached the end
OF her period Of lactation. In other
words, whether as result of feed
ing the tallow or otherwise, there
