Abstract

The possible risk factors associated with outbreaks of Pasteurella anatipestifer infection in turkeys were analyzed to study the epizootiology of the disease. The data for the study was obtained from flocks affected and unaffected with Pasteurella infection. The results of the analysis suggested that overcrowding, preexisting viral infections, increased activity of wild birds on the farm, and shorter down time were possible factors that initiate the occurrence of the disease in turkey flocks. The statistical models used in the analysis predicted correctly 80% of the unaffected flocks (8 out of 10 flocks), and 95% of the affected flocks (13 out of 14 flocks). The overall correct prediction was 88% (21 out of 24 flocks). Fish meal and meat and bone meal, which are integral components of turkey feed, were analyzed for the possible presence of P. anatipestifer. Its presence in a sample of fish meal was demonstrated.
