Fig 2. Effect of synbiotic supplementation on S. Enteritidis load in the cecal content post-Salmonella infection in broilers.
Birds were fed either basal diet (Control) or supplemented with 20 mg/Kg feed Virginiamycin (antibiotic) or 0.05% synbiotic product from day-of-hatch through 42d of age. At 21 d of age, birds were challenged with 1 X 109 CFU of S. Enteritidis. At 3, 7, 14, and 21 d post-infection, cecal content were analyzed for S. Enteritidis load by real-time PCR collected and expressed as log values. Bars (± SEM) with no common superscript (a, b, c) differ significantly (P < 0.05). n = 8.
