¹Mean and total SEM are list in Separate columns, n = 8
²a, b, c mean values within a row with unlike superscript letters were significantly different P < 0.05
³CON, pigs were fed with a basal diet; CSL, pigs were fed with a SL containing diet, 5 g/kg; ECON, pigs were fed with a basal diet and challenged by ETEC; ESL, pigs were fed with a SL containing diet and challenged by ETEC
