The foot and mouth disease, caused by Aap, was first introduced 
into the Ukraine from the bordering regions ee the RSFSR, in the 
Autumn of 1965. During a fairly short peried of time this epzoo+ 
tic spread to many regions of the Ukrainian SSR. In 1966, the 
foot and mouth epizootic continued to spread throughout the Repub~ 
lic, causing fresh outbreaks; in 1967, the epizootic decreased 
substantially, but by 1968 - 1969 there were still some epizootic: 
flare-ups of foot and mouth disease in the Ukrainian Republic. 
The scientists of the Department of Epizootology and parasito- 
_ logy of the Ukrainian Order of the Red Banner of Labor Agricultural 
_ Accademy, carried out a detailed study of the foot and mouth epi- 
_ gootic caused by Ano virus. Their investigations included collec- 
_ tions of data for stucy by scientists, This data was obtained from 
 @ survey of 187 farms during the epizootic and after the epizootic 
_ was over ( farms being selected according to their representative 
¢@haracter), The data thus obtained was analysed and tested by the 
Scientists. On the basis of these studies definite conclusions 
_ have been reached. 
This article outlines a series of basic problems of foot and 
_ Mouth epizootic, caused by App virus. } 
HE AGEeWISE SUSCEPTIBILITY OF VARIOUS KINDS OF ANIMALS. 
| At the commencement of the epizootic (1965-1966) foot and 
Mouth disease attacked mainly cattle, a few pigs and a very few 
Gheep also. By 1967-1968, the number of pigs that became victin 
to foot and mouth disease had increased appreciably. At the same 
time, it was observed that the epizootic flare-up among these 
types of animals occurred mostly on farms where many cattle, had 
in the past, contracted foot and mouth disease. 
Analysis of the data obtained, established that the most 
Susceptible animals in farms to foot and mouth disease are first
