Fermented Liquid Feed (FLF) can reduce the transfer and incidence of Salmonella in pigs.

Surveillance studies have shown that feeding pigs liquid diets, and particularly fermented liquid diets reduces the incidence of Salmonella positive herds. Studies have shown that a concentration of 70 mmol kg-1 lactic acid is bacteriostatic to Salmonella and that concentrations \u3e100 mmol kg-1 are bactericidal. Uncontrolled natural fermentation results in lactic acid concentrations varying between 0 and 140 mmol kg-1 so cannot be relied upon to produce bactericidal levels of lactic acid. However, if selected lactic acid bacteria are used as inoculants and the temperature of the fermentation is controlled (circa 30∞C), acid onditions can be produced within 24 h that rapidly and effectively exclude enteropathogens from the diet
