46 Report oF DEPARTMENT OF ANIMAL HUSBANDRY OF THE 
Jane was killed just prior to the test as she was failing fast. 
The disease had vigorously attacked her liver which probably ac- 
counted for her breaking down in about a year after she had con- 
tracted tuberculosis. 
Lest of December, 1902.—In the sound herd, Belle of Spring 
Brook and Pet had been sold for beef. The eleven animals re- 
maining from the previous test failed to react as did the calf of 
the tuberculous Aurora, giving us a total of 12 sound animals. 
In the diseased herd five animals had been sold for beef and 
Cassy, who was breaking under the disease, was killed. The au- 
topsy showed fairly generalized tuberculosis. Of the eight re- 
maining cows, Cow No. 9 was not tested because she was abou 
due to calve. The other seven were tested and all reacted except 
Millie D. 
Test of April, 1903.—The twelve healthy animals and the three 
calves, all from healthy cows, failed to react making a total of 15 
sound animals. The tuberculous herd was not tested. Cow No. 9 
died with milk fever just after the date of the previous test, leaving 
but seven diseased animals. 
Test of December, 1903.—The sound herd, consisting of the 
fifteen head at the last test, now numbered twenty, three of the 
five calves coming from the diseased herd. All passed the test. 
In the diseased herd Aurora was not tested because she was 
about due to calve and of the remaining six only Chloe and Nettie 
gave a reaction. No satisfactory reason can be given for the 
failure of the other four to react. 
Test of May, 1904.—The sound herd contained twenty-four ani- 
mals at the date of testing, two of the four calves dropped since 
the last test coming from’the diseased herd. A single animal, 
Daisy of Loch, gave a typical reaction with the tuberculin, leaving 
us 23 sound animals. Almost immediately following the test this 
cow became so lame as to be practically helpless. Treatment failed 
to relieve the trouble and she was killed. An autopsy showed the 
presence of a few tubercular lesions in the mediastinal glands. This 
was evidently a case of recent infection and as we obtained a re- 
action at the same test from a cow which had been added to the 
herd by purchase an explanation of the avenue of infection seems 
simple. This was the first case of infection in our sound herd 
after the separation in I9oI.
