^aNC, piglets were fed the daily diet and received oral administration of sterile physiological saline; PC, piglets were fed the daily diet and received oral challenge with ETEC K88; PC + CB, piglets were fed the CB-supplemented diet and received oral challenge with ETEC K88. Values are means ± standard error.
