Extract

Consumption of poultry meat is associated with human Salmonella infections (Revolledo etal. 2006). One way to control the presence of these bacteria in broiler flocks is to make chickens less susceptible to colonisation. Fermented liquid feed may be a potential tool to reduce the Salmonella carriage in broiler chickens (Heres etal. 2003). Fermented liquid feed is a moistened feed with high numbers of lactobacilli (=109cfu/gr), high concentration of lactic acid (= 150mM) and a low pH (<4.5) (Brooks etal. 2003). In the present experiment, a strain identified as Lb. salivarius that has been isolated from chicken gut and has been selected for its probiotic and fermentation properties after a screening method, was assessed for its efficacy in reducing the shedding of Salmonellatyphimurium in poultry.
