The effectiveness of scientifically based monitoring programs and therapeutic and preventive measures for controlled infectious diseases of animals

The aim of the work was to assess the effectiveness  of  an  improved  monitoring program  for  controlled  infectious  animal diseases  and  individual  vaccination  programs for acute respiratory viral infection in cattle.  To  fulfill  the  tasks  set,  serological studies, PCR diagnostics, bacteriological and coprological methods of examining biological samples from animals were carried out. As a result of the work, the main factors influencing  the  effectiveness  of  vaccine prophylaxis of acute respiratory viral infection in cattle populations have been identified. It was found that in three administrative and  administrative  districts  of  the  Sverdlovsk region, the main factors in 35.1% of cases are violations of the rules of vaccination  of  acute  respiratory  viral  infection  of cattle, in 13.5% of cases - violations of zoo-hygienic  and  veterinary–sanitary  conditions of keeping farm animals. A comprehensive assessment of the effectiveness of individual vaccination programs for cattle against acute respiratory  viral  infection  has  been  carried out, taking into account the epizootological situation in agricultural organizations. It was shown  that  vaccination  of  cattle  against acute respiratory viral infection according to individual  programs  ensured  the  formation of specific immunity in 92.5-95.0% of animals.  The  number  of  immunotolerant  individuals and animals with a low level of immunoreactivity in the physiological group of young  cattle  did  not  exceed  3.5%,  in  the physiological  group  of  adult  animals  – 1.25%.    The  high  efficiency  of  improved scientifically based programs for monitoring, diagnosis, therapeutic, preventive and health measures  to  protect  animals  from  epizootically significant infectious diseases of cattle among  the  populations  of  farm  animals  of the Ural Federal District has been confirmed.
