Methods of microbial treatment of poultry
Disclosed are methods of administering one or more Bacillus strains to poultry. The Bacillus strains improve bacterial homeostasis in the gastrointestinal tract by inhibiting bacterial pathogens such as E. coli and Clostridium . Administering the Bacillus strains also improves performance such as weight gain and feed conversion. Useful combinations of Bacillus strains and methods of using one or more Bacillus strains are also provided.
