Two similar trials were conducted to evaluate the effects of 2.5% d-mannose (DM) in the drinking water of broilers for the first 10 days on incidence and levels of salmonellae in the ceca and on the carcass at market age. Controls received drinking water with no DM. Birds were reared on used litter in floor pens and were inoculated via the drinking water with 10(8) cfu/mL Salmonella typhimurium (ATCC 14028) on Day 3. At 49 days, 60 birds per treatment were processed and the ceca contents and prechill carcass were evaluated for salmonellae incidence by the most probable number (MPN) method. Results were inconclusive: level of salmonellae in the ceca contents and carcass rinse was significantly lower in control samples than in DM samples in one of the two trials; the reverse was true in the other trial.
