Abstract:
Respiratory tract diseases constitute one of the most important causes of economic loss to the swine producer. Particularly in intensive animal production large groups of sows, early weaning and shifting of piglets lead to a different immune status of the pigs and thus to a different susceptability for pathogens (HALBUR, 1998). In most cases multiple infections by viruses and bacteria occur in addition to noxious gases, high dust loadings, low air temperature and a bad operating management which are additional negative factors. No clear connection between causative agents and pathomorphological lung changes could be determined in this study. Bacterial infections were surprisingly often accompanied by an interstitial pneumonia. The high number of animals with pathological lung changes was particularly remarkable, with which no specific agent could be proven. However, it could be stated that with a rising number of different agents, the degree of the pathological changes increased. The conclusions of these results are, that the selection of the animals, which are sent in for investigation should be made more critically, that an exact anamnesis for the selection of the investigation methods is essential and laboratory findings should be interpreted more critically.
