FEEDING DAIRY CATTLE.

Professor Pearson said the matter of
feeding dairy cattle had long been con-
sldereo by the Department of Agricult-
ure, ana experiments which were being
made would be published next winter.
PROFESSOR Pearson described the sew
efai kinds of fat which enter into the
composition of milk, and of those which
are contained in the food given to the
animal He said the idea had been,
and still was general, that the fat con-
tanned in the milk depended upon the
fat contained in the food. That idea.
he said, had been disproved by Dr. Jor-
dams experiment at the Geneva sta
ton. Dr. Jordan put the food to be
given a COW through a process by
which the fat was removed, and after
feeding her upon it a long time, found
that there was even more fat in her
milk than before the fat had been re-
moved from the food.
Professor Pearson said that the solid
ity of the butter produced depended
upon the component parts of the fat
solids and oil. 1t was noticeable he
said, that some of the butter placed on
the market stood up even on hot days.
while other lots were oily. The De-
partment of Agriculture had COM
menced investigation as to the cause,
and would publish the results of the
investigation next winter. He as yet
could give no indication of what it
would be.
The Governments chemist, he said
had made analysis of the oils and SOL
ids of butter produced from different
kinds of feed, and he felt that study
of the fat itself was necessary to ara
rive at a fair conclusion of the food
necessary to produce butter which
would stand a high temperature.
BARLEY AND OATS GOOD.
VIM. Fl. Locke of Lockeford, San
Joaquin County, said that barley stub
BILE was an excellent food for cows when
hard butter was desired The butter
produced from his herd while feeding
on such stubble was as white as tallow
and nearly as solid
Professor Jaffa said that tests made
in Kansas had shown that oat fed COWS
produced extremely hard butter.
President Martin said his experience
had taught him that COWS fed on pota-
toes would produce hard, solid butter,
but 1t was not good for the cattle to
feed them too heavily.
GREEN CORN THE BEST.
VIM Johnson said he knew of no feed
for cows to equal green corn. He felt
confident that the feed had much to do
with the quality of butter produced,
but that changes of diet were neees-
sary. He knew of no better feed than
corn and alfalfa
HARD BUTTER WANTED.
Professor Jaffa said it seemed to him
that there was nothing so important to
the dairymen as to produce a good,
hard butter which would stand eX-
portation. He thought hard butter
might be made as cheaply as soft, and
thought the component parts of the
fat itself ought to be closely studied,
together with the feed producing each
particular fat. The size of the globule,
it was claimed, he said, had much to do
with the frmness of the butter. the
larger globules containing more oil, and
consequently making an oily soft but
ter. It was also claimed, he said,
that the Jerseys gave large fiat glob-
ules and the Holsteins small ones.
These were things which should be
studied closely, as we'll as the question
of food.
Professor Jaffa said the fat in the
food had nothing whatever to do with
the fat in the milk. What was neces-
sary, he said, was to have certain
amount of protein in the food Alfalfa
was the best food for protein, but it
would produce soft butter and finally
result in injury to the COW, if fed alone.
Alfalfa and corn silage, fed together he
said, gave probably the best results.
| He said that cotton seed meal was
more prolific in protein than any other
meals on the markets. but that it would
| if fed to excess, taint the butter. He
thought that grain of some kind ought
| to be fed to COWS, together with hay
alfalfa or otherwise. 1t had been
shown, he said, that corn ever pro-
duced hard butter, and it had been as
serted that sugar beet silage would
produce soft butter. That question
however, had not been settled. He
thought that if fifty or sixty pounds
of the beet pulp silage was given each
COW daily, the result would be found To
| be satisfactory 1t had been shown
by experiment that two or three pounds
of solid food, given in conjunction with
| the silage, kept the COWS in good,
| healthy condition. Even if, he said
| quality of butter, it would certainly
give an excellent article for home con-
| sumption.
+ Pumpkins, Professor Jaffa said in an
swer TO a question, were good food for
| COWS, because, being succulent, they
assisted the cow in assimilating much
more rough feed than she could dc
without it.
COTTON SEED MEAL.
Quite discussion followed on the
advisability of feeding cotton seed meal
| Chairman Martin contended that the
meal, having three times the nutrition
| of bran, was the cheaper of the two
feeds Very little of it, however, is
being used in the State, owing to the
excessive freight rates from Eastern
points. He could not, he said, advise
the use of cocoanut meal unless it was
perfectly fresh, as it would if kept a
| long time, become rancid and affect the
quality of the milk.
Professor Pearson raised the question
as to whether or not the time of feed
| ing had anything to do with tainting
the butter, and the opinion prevailed
that the feeding should be done after
milking, for the reason that some foods,
| if taken at or a few hours before milk
| ing, would become tainted, whereas II
| taken ten or twelve hours before milk
ing, the COW would get the benefit OF
tho food and the evil effects MOULD
