The present invention comprises a novel strain of Lactobacillus johnsonni FERM BP-2680, a lactic acid bacteria preparation using the Lactobacillus johnsonni FERM BP-2680, and a process of manufacturing the lactic acid bacteria preparation. The process includes the steps of inoculating the Lactobacillus johnsonni FERM BP-2680 into a medium containing fermentable sugar as a major carbon source, cultivating and proliferating under cultivation conditions adapted to anaerobes or facultative anaerobes, and further isolating the Lactobacillus johnsonni from the medium and drying the isolated Lactobacillus johnsonni with a protective agent to produce the lactic acid bacteria preparation. Optionally a bulking agent may be added to control cell concentration of the preparation. The preparation containing Lactobacillus johnsonni FERM BP-2680 is used to suppress harmful bacteria in the digestive tract of mammals.
A method of establishing direct feed microorganisms such as Lactobacillus reuteri in the gastrointestinal tract of avian organisms, in which the direct feed microorganisms are added to whey and fed in the form of pellets (compacted whey particles) to the organisms.
New strains of L. acidophilus capable of adhering to the tissue cells of various species of animals and having resistance to both erythromycin and streptomycin are described. The strains may be used in a suitable carrier as a dietary supplement for providing a source of the bacteria in an animal.
A ruminant direct fed microbial composition of matter comprising an acidosis inhibiting effective amount of Propionibacterum P-63 is provided. Also disclosed is a process for reducing acidosis in ruminants or scours in swine by administration of the bacterium to the ruminant or swine. The microbial composition may be administered by itself, or combined with animal feed and/or lactic acid producing cultures.
