Measures for the protection of farms free of brucellosis 
are basically with the ones recommended for controlling the 
brucellosis. ‘faking into account the possibility of latent 
transmission of brucellosis in the young ones and imperfection 
of diagnosing brucellosis in the republic, the young ones 
obtained from the uterus of cows from a farm having brucellosis 
was introduced to farms free of this disease. This was independ- 
ent of the method of raising the young ones. In addition, all 
animals having contact with animals suffering from brucellosis 
were also introduced to farms free of brucellosis. 
Serious attention has been paid to the prevention of 
contact of different sanitary groups of cattle at the pastures 
during displacement of the animals to indoor maintenance as 
well as contact with domestic animals belonging to the citizens. 
For the prevention of distribution of the infection along 
with milk products, all the factories working on the processing 
of milk in the republic were asked to return milk to the collect- 
ive and state farms only after pasteurization and before feeding 
the milk to the young ones, and they should once again make it 
harmless at the farms. 
Depending on the degree of distribution and character of 
transmission of the brucellose infection in the area or region, 
the farms having brucellosis are kept clean by the following 
basic means: 
1. By way of systematic complex serological investigations 
of the cattle and slaughtering of the animals giving positive 
results of brucellosis. 
This method is applied in farms with little distribution 
of the disease as well as for the protection of the cattle 
belonging to the personnel of the collective farms. 
2. By the method of prophylactic inoculation of the young 
ones of the cattle with vaccine against brucellosis in the 
complex along with other anti-epizootic measures. This method 
is applied in farms with large distribution of infection where 
it is impossible to undertake healthy protective measures by 
way of substitution of the particular young ones with the young 
one brought from the farms which are without this disease,
