Technical Abstract: A commercially available Lactobacillus probiotic (FM-B11â„¢ Ivesco LLC) (B11) significantly reduced Salmonella recovery from day-of-hatch chicks in several studies. For all experiments, day-of-hatch male broiler chicks (n=40 per pen) were challenged with approximately 10**4 cfu per chick of Salmonella enteritidis (SE) or Salmonella typhimurium (ST) and 1 h later treated (as below). Cecal tonsils or cecae were harvested for Salmonella detection 24 h following treatment. In experiment 1, oral administration of 10**6 or 10**8 cfu per chick of B11 significantly reduced SE recovery by 82% (p<0.05) as compared to untreated controls whereas 10**4 cfu of B11 had no effect. In experiment 2, oral administration of B11 killed with penicillin or heat caused no reduction in SE recovery. In experiments 3, 4 and 5, B11 significantly reduced SE or ST recovery as compared to controls. Additionally, there was a 3 log10 reduction in cfu of SE recovered from cecae of B11 treated chicks as compared to controls in all three experiments. In experiments 6 & 7, the recovery of SE from the control and treated groups of 6 and 12 h following B11 treatment was not different, but at 24 h B11 a significant reduction in SE was observed as compared to controls. In experiment 8, again at 6 and 12 h following B11 treatment, SE recovered from the control and treated groups were similar, but at 12 h B11 caused a significant 1 log10 reduction in cfu of SE from the cecae as compared to controls. This difference continued to increase over time as significant 1.5 and 2.5 log10 reductions were observed at 19 and 24 h respectively. Sufficient concentrations of live B11 significantly reduce Salmonella recovery in day-of-hatch chicks.
