title: [Combined prevention of viral infections in cattle].
abstract: On the basis of clinical observations and serological investigations a mixed type of virus infection of MD-VD parainfluenza-3 and adenovirus I was established. A complex prophylaxy against the virus infections proved in 2,800 heads of cattle was carried out, also on 1,400 heads of growing animals at the age between 6 and 18 months, as well as on 2,777 calves at the age of 6 months. The results of the immunoprophylactic actions showed the leading role of MD-VD in a virus infection. Owing to the steps taken the respiratory syndrome in the calves and in the cows was suspended. The falling away of calves was reduced from 15.4% to 3.2%, and the average daily growth was increased from 220 to 470 grams.
