Persistence of Escherichia coli, Salmonella choleraesuis, Aujeszky's Disease virus and Blue Eye Disease virus in ensilages based on the solid fraction of pig faeces

Aims: This study was carried out to determine the survival time of Escheric hia coli, Salmonella choleraesuis, Aujeszkys Disease virus and Blue Eye Dis ease virus in ensilages based on the solid fraction of pig faeces. Methods and Results: The four micro-organisms were inoculated into microsil os based on the solid fraction of pig faeces, sorghum and molasses. They we re left for 0, 7, 14, 28 and 56 days, after which the state of each microsi lo was evaluated, and isolation of the inoculated agents was attempted. The four inoculated agents were isolated only on day 0 of ensilage. The viral agents were identified through the cytopathic effect and fluorescence. Conclusions, Significance and Impact of the Study: It is concluded that ens ilages, based on the solid fraction of pig faeces appear to reduce the risk of the transmission of the agents inoculated in this study and help to red uce the environmental impact by using the solid in animal feed.
