PRACTICAL VALUE OF TUBER~
CULlN.


diagnostic of tuberculosis of cattle
has been undoubtedly abused in many
instances where forcible entry was
made into private stables by unpro-
fessional, uneducated employees Of
state officials, the fact remains that it
Is, properly used. a reliable and valu-
able agent In detecting the presence
OF the disease. There need be nothing
hidden in the use Of tuberculin. Any
intelligent farmer may use it success.
1ully himself with little instruction.
we have given such instruction many
tlmes and results following the first
use OF the agent have been more than
successful. This being the case we
lave always advised that tuberculin
snould De employed when there is rea-
eonaole suspicion in the mind of an
oWner that one of his cattle NAV be
aHlcted with tuberculosis and more
especially when the udder is the seat
OF the trouble.
we ind that it is a common thing
lor a mich COW to show the following
symptoms: Tie udder becomes caked
(gargetty) now and then and recovers
"1tnout treatment. There is no good
reason Tor the attack. The COW suf-
ters no chill or fever. She eats well
and appears healthy. The milk from
tne aHected teat or quarter is changed
IN quality for but few days then be-
comes normal again. tuberculosis is
never suspected by the owner, but, in
tnese cases we always suspect it and
consider it by far the most danger
Gus form of the disease so far as users
OF milk are concerned.
Quite recently a cattle breeder sent
US the following report of a COW owned
by him: "A four-year-old COW dronned
ner hrst calf, carried full time. mir
teen months ago, and has not stood to
service vet. She was a yerv moor
mixer and the calf was taken from
her when three or four months old and
'ne co" dried OFF. In short time it
was noticed that one of her rear teats
was larger than normal, as though it.
nlsnt nave been caked a little in drv-
lug ner up. lt1&.as gradually increased
IL SIZE until now that quarter of the.
uooer is about five inches across. hard
and hot. What shall l do for il? Tho.
COW seems in first rate general health
WIN the exception of one eye which
became lrritated while on pasture last
summer and seems blind now. She.
nas mad no grain for several months.
DIS tnought it possible she would he.
more apt to breed if reduced in flesh.
An examination shows the mouth Of
tne womb SO tightly closed that !

ruooer d1lator about n inch in d.
ameter. What do you think of the.
| case?"
Inc owner was advised by us that
we suspected tuberculosis and given
1uH instructions as to the making OF a
tubercul1n test. He acted upon this
advice, procured the necessary ther-
mometer, hypodermic syringe and
dose OF tuberculin and made the test
OF which the following is report:
Temperature of COW prior to iniec-
ton OF the tuberculin, a. M, 1922:
1880 a. M, 103; 6:15 p. m, 1898. In
)ected 3 cubic centimeters of tubercu-
lin under skin OF neck at $3.50 D. m.
same day preliminary temperatures
were taken. Next morning tempera-
lures were again taken with following
results: a. NJ, 1868; 9 a. M. 1918:
IL noon, 1912; p. M, 1913; s D. M.
1918
This is most Interesting case. Cow
reported to be Gin first rate general
health" with not the slightest sus-
picion of tuberculosis on the part OF
the owner was by the above tuberculin
test proved to be very dangerously
tuberculous. Her udder was doubtless
the seat of the disease, but glands
throughout the body were also no
doubt involved in the disease. The
COW that has stood next to this COW
In stable for some time was also tested
and showed by her reaction to the
tuberculin that she is to be consid-
cred suspicious and a subsequent test
In few months may show plainly
that She has contracted the disease
without doubt. There is surely a
valuable lesson to be learned from
this case-Farmers' Review.
