Synbiotic modulate the host immune response to Salmonella typhimurium infection in commercial and indigenous chicken

This study examined the effect of the synbiotic product (PoultryStar®me) on Fayoumi and Cobb chickens upon exposure to Salmonella typhimurium (ST) infection and compared the responses of Fayoumi and Cobb chickens to ST infection. Fayoumi and Cobb chicks were fed synbiotic 1 g/kg feed from the first day. At 21 days of age, the chicks were orally challenged with 3 × 1012 cfu ST. At 72 h post-infection (pi), Fayoumi chickens showed significantly lower bacterial loads in their livers than Cobb chickens (p
