Commission Report: Tuberculosis. 9 
It is further recommended that the discovery of tuberculosis 
in animals coming under government inspection should be used 
whenever identification is possible, as a means of locating infected 
herds and premises. All such cases should be reported to the 
proper authorities for control action. 
RESOLUTION 6. DISPOSITION OF TUBERCULOUS ANIMALS. 
THE COMMISSION PLAN. 
1. As a general ‘policy in the eradication of tuberculosis the 
separation of healthy and diseased animals, and the construction 
of a healthy herd are recommended. 
In order to accomplish this, the following recommendations 
are made :— 
(1) If the herd is found to be extensively infected, as shown 
by the tuberculin test or clinical examination, even the apparently 
healthy animals in it should be regarded with suspicion, until 
they have been separated from the reacting animals for at least 
three months. 
If after the expiration of this time they do not react to the 
tuberculin test, they may be considered healthy and dealt with 
accordingly. 
It is recommended that a herd extensively infected should not 
be treated by the method of general separation, but that the con- 
struction of a new herd from the offspring only is advisable. 
(2) If the herd is found, by either or both of the above 
methods, to contain a relatively small proportion of diseased 
animals separation of the diseased animals from the healthy ani- 
mals, and the construction of a sound herd from the healthy 
animals, and the offspring of both, is advocated. 
As a working basis in carrying out these principles, we advise, 
(a) That herds containing fifty per cent or more of diseased 
animals be treated as coming under section one. 
(b) That herds containing under fifteen per cent of diseased 
animals be treated as coming under section two. 
(c) That herds falling between these figures be graded accord- 
ing to the option of the owner. 
(d) That it shall be the prerogative of the owner, to reject 
either plan and have his herd dealt with by removal and slaughter 
of diseased animals, with or without compensation, according 
to the public policy in operation.
