Production Layer Salmonella Enteritidis Control through Dry Fed Pre & Probiotic Products

Increasing interest in multiple strain Bacillus probiotics and parietal yeast fractions as feed ingredients for egg laying hen diets has also led to food safety questions. This study was undertaken evaluate the ability of these products reduce Salmonella Enteritidis colonization. Sixty Hy-Line hens aged 56 weeks were placed individual cages fed a mash diet containing one following treatments, control, spp. probiotic, cell wall, or combination wall probiotic. At 60 age all challenged orally with 7 x 107 CFU/bird Enteritidis. 61 age, birds humanely euthanized, by cervical dislocation ceca aseptically removed cultured S. prevalence number Most Probable Number method. There no significant difference between control any treatments. The had 4.37 log10 MPN/g detected ceca. Probiotic group 2.96 MPN/g, reduction 1.41(p<0.05) 2.89 1.48 (p<0.05). 3.60 numerical 0.78 (p=0.14). probiotic groups significantly reduced amount hens.
