standing OF even careful StuQ6Q1SR
said Professor Woll, discussing
Yeksa Sunbeam's record. What
was considered beyond the range of
possibility yesterday has been reach
ed today. Yeksa Sunbeam's record
for the past year of IA, 92O8 pounds
OF milk and 857 15 pounds of butter
fat, or an average fat content of
ETA per cent for the year, is the.
highest on record in the world.
This is 287 z pounds more than the.
highest record for annual milk pro-
duction of any Guernsey COW, and
81 6 pounds more than the high
est authenticated record for the
production of butter-fat during a
year for COWS of any breed. These
records for Guernsey COWS were
held up to this time by Imp. Rosie,
for milk with IA, 633 pounds, and by
Imp. Princess Rhea for butter-fat.
with 1855 pounds to her credit.
when we consider that dairy
cow yielding less than one half the,
amount of milk and one-third the,
amount Of butter-fat produced by
Yeksa Sunbeam is generally looked
upon as very good cow" con-
tinued Professor Woll,'' and that
the average annual production of:
butterfat by Wisconsin COWS is not
much over $50 pounds, the produc-
ton OF this Guernsey cow becomes
truly phenomenal. 1t means that
the cow produced on the average
400 pounds Of milk and g. So pounds
Of butter-fat per day for every day
Of the year. 1t the amount of
butter which this fat would make Is
calculated by the genera ly accepted
rule of the addition of one-sixth.
we find that she produced an
average of 275 pounds of butter per
day, and for the entire year, Oct. 1,
1904 to Sept. 80, 1905, total of
1,000.02 pounds"
The conditions under which
these records were made will doubt
less be of interest to many who are
engaged in dairy farming or are
breeders of dairy cattle. The daily
milk yields we're reported to the
secretary OF the American Guernsey
Cattle club each month by the
breeder himself, and the quality Of
IL e mi K for single day, when the
repl SENTATIVE of the University OF
Wisconsin Experiment station ,ame
to the farm to test the COW, was
used for calculating the product of
butter-fat by the COW for the
month. At the same time note
was made by our representative of
some of the daily milk yields dur ng
the few weeks preceding the test
ing day and this was reported to
the secretary, who is charged with
the duty OF checking up the figures
for milk yields reported by the
breeder. Not only must the yields
of milk sent Id by the breeder cor
respond with those reported by the
station supervisors or dairy tests,
but the daily yields before and
after the day Of the monthly test
must be about the same ais determin-
ed by our representative In the
monthly test. This was the case in
the test of Yeksa Sunbeam.
1.-THE production of butter-fa fat
ascertained by this method of test
ing the milk Of the cow for single
day each month is found to be
substantially correct; that is, 1t
cent from the figures obtained if
each and every milking, or correct
composite samples of all milkings,
be tested and these percentages
multiplied by the number of pounds
of milk produced by the cow. The
figures obtained on the yearly test
Of Yeksa Sunbeam, as conducted by
the Guernsey association with the
assistance of this station, show
therefore that the COW produced in
reality during twelve consecutive
months anywhere between $50 and
865 pounds of butter-fat, but since
the exact production could not be de-
termined, we are perfectly safe and
justified IN accepting as correct the
amount with which she is credited
by that association according to the
system of semi-official testing
857 10 pounds of butter-fat, equiva-
lent to 1000 OF pounds of COM
mercial butter.
This figure is one that is likely
to stand for a long time as the
record for years production of
butter-fat by a dairy cow. 1t is
81 ; pounds higher than the amount
which another famous Wisconsin
Guernsey COW, Lily Ella, was
credited with in a test conducted
during the latter part Of the COS
partly under supervision of the
University of Wisconsin station,
but before the present system had
been adopted by the Guernsey as
soclation. There is no record Of
Jersey COWS that can be compared
with it. The test of Bisson's Belle
of 1923 pounds 155 ounces of butter
made from s, 4l2 pounds z ounces of
milk is very questionable and is not
believed in today by any breeder in
