Efficacy of dietary supplementation of bacteriophages in treatment of concurrent infections with enterotoxigenic Escherichia coli K88 and K99 in postweaning pigs

Postweaning pigs challenged with enterotoxigenic Escherichia coli (ETEC) K88 and K99 and fed a diet supplemented with ETEC K88- and K99-specific bacteriophages exhibited greater weight gain, lower fecal consistency score, and less fecal shedding and intestinal adhesion of ETEC K88 than did pigs fed the unsupplemented diet.
