Salmonella colonization of fowl may be effectively controlled or inhibited using a defined composition of anaerobic bacteria as a probiotic. The probiotic includes a first culture of substantially pure Veillonella effective for fermenting lactic acid to produce volatile organic acids including acetic, propionic and/or butyric acids. A second culture of at least two anaerobic bacteria selected from Streptococcus intermedius, S. morbillum, Enterococcus durans and Lactobacillus acidophilus effective for fermenting carbohydrates to produce lactic acid is also used in combination with the first culture. These first and second cultures are administered to fowl in amounts effective for inhibiting Salmonella colonization. In one use, the probiotic bacteria may be combined with conventional feed, providing a feed product that can be orally digested by fowl.
