Manhattan Experiment station on the
Vaccination Plan

He
Manhattan, Kan. Feb. 5-1'bA agrio,,,-
1urai experiment station here has issued
Press Bulletin No. 81 on Protective
incubation against Blackleg in Cattle 3"
as follows:
During the year 1899 and part of tina
year 1898 the Veterinary department of the
Kansas experiment station has sent ont
material sufficient TO inoculate about 100
O0l head of susceptible cattle. This, ma
1er1al was sent free to ALL applicant.
owning cattle in Kansas. The obiaot of
the experiment was to study the value of
protective incubation, the best methods
OF incubation and the prevalence and ex-
tent Of blackleg in Kansas. The results
an orlet' are given below. A preliminary
bulletin on this subject is in preparation
and will soon be ready for distribution.
Extent-Blackleg exists in practically
every county IN Kansas. We have deAn.
ate reports to this effect from all but seven
counties.
Occurrence, The disease occurs in cattle
OF all ages and both sexes. The most
susceptible age is six to thirteen months
Human beings are immune.
Mortality.-In 1895 the death rate from
olaokleg was q of per cent of the entire
cattle herds Of Kansas. In 1897 the death
rate was slightly greater and in 1898 the
death rate was nearly twice as eraat &c

1888 lost at least ~ per cent Of 1000 90

This would be a loss Of 10000. cattle with
a value of atleast sSco, zoe This loss could
have been almost entirely prevented. h

During 1886 1887 and 1888 20 per cent of all
cattle owners in Kansas sustained losses
from blacileg In 1855. out Of 81 eattIs
owners. one hundred owners lost over AZ
per cent OF their entire herds, comprising
1855 animals. II 1892, one hur6erd and
forty"six cAttlensH report an average loss
Of over per cent Of their entire herds
Treatnent-Curative treatment IL nor

OBSERVATION-DISCLOSURES is the only

OF susceptible animals can be saved.
Place Of Observation-Disclosures NAV h.
vaccinated in the end of the tail. shoulder
ear and ether places. The loss from black
leg and other causes as a result Of vacs
cfnation in the shoulder. thigh. ear. etc.
Is about Is Of / per cent. The loss result
ing from tail incubation is less than I-lo
81 per cent, a showing decidedly in
favor Of tail incubation. Tail incubation
IS a little more difficult to pert6rm but
paws best on small and valuable herds
Immunity produced by vaccination last
about one year. but the time varies with
the ace of the animal at the time OF
vaccination and with other conditions All
animals above three months old and BE-
low the ase Of thirty 70 thirty-six months
shouii be vacclnate5 every year II cattle
