Method of using chitosan to reduce shedding of E. coli from bovines

摘要

A method to reduce fecal shedding of E. coli from bovines is described. The method includes administering an amount of chitosan to a bovine. The amount administered is sufficient to reduce or eliminate fecal shedding of E. coli from the bovine. Also described is a corresponding feed ration for bovines. The feed ration includes chitosan as an active agent to reduce or inhibit shedding of E. coli from bovines, including the shedding of pathogenic E. coli such as strain O157:H7.
