Effect of feeding a non-medicated, medicated or B. pumilus treatment for 22 days post-weaning on fecal bacterial counts (log10 CFU/g) of pigs and fecal counts of the administered B. pumilus strain.1,2,3

1Mean values with their standard errors, n = 12.2Bacterial counts are presented as log10 CFU/g wet weight.3Within each row, values with different superscripts are different at (a,b) P4Non-detectable (the limit of detection was 100 CFU/g i.e. log10 2.0 CFU/g), although at d 0 low values were recorded for the vegetative cells + spores count in some pigs, representing background rifampicin resistant microflora.
