The authors emphasize five areas of biosecurity management that should be more rigorously applied for the reduction of respiratory disease prevalence in cattle, including (1) strategic vaccination, (2) calf biosecurity, (3) housing ventilation, (4) commingling and animal contact, and (5) bovine viral diarrhea virus control. Airborne pathogen concentration is a function of many factors, including animal type, housing system, stocking rate, bedding, humidity, dust particle density and size, and finally, elimination through ventilation. Because the pathogens involved in bovine respiratory disease are enzootic in the general cattle population, biosecurity practices aimed at the complete elimination of exposure are currently impractical.
