Lactic acid bacteria and their use in swine direct-fed microbials

摘要

TRFs useful for identifying strains of interest are provided. A method of identifying one or more strain that can be used as a direct-fed microbial is also provided. One or more strain identified by the method is additionally provided. A method is also provided for administering to an animal an effective amount of the one or more strain. Additionally provided is an isolated strain chosen from at least one of Lactobacillus acidophilus strain PlB C6 (NRRL B-50103), o24&oacgr;e 33w (NRRL B-50102), o246e 42 (NRRL BoOl 71), and strain PU e3 (NRRL B-50101). An isolated strain having all of the identifying characteristics of one of the strains listed above is also provided. One or more strain can be administered as a direct-fed microbial to an animal. Methods of preparing a direct-fed microbial are also provided.
