Mucosal competitive exclusion (MCE) cultures generated from the mucosal scrapings of healthy adult turkeys were administered to commercial turkey poults. MCE-treated poults were placed on tom and hen farms with paired untreated control poults in adjacent houses. After 6 wk in the brood house, cecal droppings from control and treated flocks were collected and analyzed for the presence of salmonellae. Salmonellae were detected in 14 of 30 cecal droppings (47%) from control flocks and from only 1 of 30 (3.3%) droppings from the treated poults. This study demonstrated that mucosal competitive exclusion could be used to effectively control salmonellae in a commercial field trial of young turkey flocks.
