1Definition of acronyms: CTRL = No probiotic and no antibiotic; ATB = tiamulin and chlortetracycline; PA = P. acidilactici; SCB = S. cerevisiae boulardii; PA + SCB = a mixture of the two probiotics.
2Pooled standard error of the mean (SEM); n = 8/treatment, except for SCB, n = 7.
3Results are expressed as Log10CFU of ETEC F4/g of tissue.
4Results are expressed as the median. Scale used was: 0 = normal, solid contents; 1 = soft intestinal contents; 2 = semi-liquid intestinal contents; and 3 = liquid conten
