SUMMARY
The article contains data on manifestation of
epizootic process at mixed infection caused by infectious
bovine rhinotracheitis (IBR) virus and parainfluenza
3 (PI 3) virus in cows in the conditions of a dairy
farm. <...> Goal of investigations was to reveal some predisposing
factors for occurrence and manifestation of
mixed infection caused by IBR virus and PI 3 virus. <...> During the epizooty 270 cows of black white breed
were under surveillance. <...> It was established that
predisposing factors for occurrence of mixed infection
caused by IBR virus and PI 3 virus in cows were
poor nutrition and sharp change in diet. <...> Clinical
manifestations of mixed infection caused by IBR virus
and PI 3 virus in cows were apathy, decrease of
palatability of the feed by 40% and of daily milk yield
by 30%, hyperthermia (in 42% of animals), hypersecretion
of mucus (in 70% of animals), cough and
dyspnea (in 50,4% of animals), mastitis (in 27,2% of
animals), abortion (in 12,5% of calved cows), stillbirth
(in 8,3% of calved cows), postparturient paresis
(in 14% of caved cows), retained placenta (in 22% of
calved cows), endometritis (in 36% of caved cows). <...> At the beginning of the development of the epizootic
process the seropositivity against IBR virus came to
66,7% at the average antibody titer 1,35 lg2, the seropositivity
against IBR virus in conditionally healthy
animals was 25% at the average antibody titer 0,67
lg2, the seropositivity against PI-3 virus was 25% at
the average antibody <...>
