An intervention study of the effect of implementing Salmonella-controlled feeding strategies in Salmonella-high prevalence herds

摘要

In this study we found a significant effect of implementing a salmonella-controlling feeding strategy for finishers, consisting of a pelleted feed where non-heat treated wheat or barley was added to the feed after pelleting. But not all trial herds reached Salmonella level I within the observation period, according to the Danish Salmonella Surveillance System, indicating the multi-factorial nature of Salmonella-infections. One issue that needs further research is the effect of the Salmonella level before entering the finishing period.
