This study investigated the potential of fermented liquid feed (FLF) to reduce Salmonella carriage in broiler chickens. In this experiment, a strain identified as Lactobacillus Salivarius ss Salivarius NCIMB 41606 (Lb salivarius) that had been isolated from chicken gut and had been selected for its fermentation and potential probiotic properties, was assessed for its efficacy in reducing the shedding of Salmonella enterica typhimurium Sal 1344 nalr in broilers. A total of 68 hatchlings were randomly divided into four groups. One group was provided with a daily dose of 107 cfu/ml of Lb. salivarius, delivered via drinking water from day one of age. The second group was provided with 109 cfu/gr of Lb salivarius delivered in fermented liquid feed (FLF). The third group (ALF) was provided with feed acidified with 30.3 ml of lactic acid/ kg of wet feed from day one of age and the last group was the control without any addition of Lb salivarius or acid. Birds fed FLF were free of Salmonella on 51% of days compared with 23% for birds fed ALF (P<0.05) and 19% for birds provided with Lb salivarius via water, and 8% of Salmonella negative days in CON birds. FLF, produced using Lb salivarius, is suggested as an effective means of controlling S. typhimurium infection to poultry.
