On an average, two anti-foot and mouth vaccinations were 
carried out per head of the large cattle, which were not attacked 
by the foot and mouth disease. These measures have ensured a 
large section of animals which were not suceeptible to foot and 
mouth infection, which was an important condition for the action 
against further spread of the foot and mouth infection in the 
Republic and elimination of the epizootic, 
The study of the development and passage of the foot and 
mouth epizootic in the Ukrainian SSR from 1965 to 1968, which was 
caused by the A virus, makes it possible to make the following 
22 
conclusions: 
1. Right from the beginning, epizootic had a quick start 
and in a short period of time (only 10 days) it gripped a large 
number of areas and a substantial number of liveestock. During 
this period (Cctober-December, 1965) there was 635% of the total 
areas affected by the foot and mouth infection for the whole 
period of the epizootic 61% of the infected live-stock of large 
cattle, 50% of pigs and 46.6% of sheep and goats infected with 
the foot and mouth virus. 
2. Maximum development of the epizootic was observed during 
the indoor maintenance of the livestock (October 1965 to March, 
1966). The period recorded 94% of all the areas that were 
affected, which included 93.8% of all large live-stock cattle 
that had been infected by the foot nd mouth virus during whole 
period of the epizootic.
