Effects of the mixture on fecal coliform and beneficial microbe population (35 days). Values are expressed as means. Contrasts of the same microbes between Control and PSO in each period are shown (e.g. Beneficial-Control vs Beneficial-PSO). *Differences in superscript indicate significance at P < 0.05. Beneficial fecal microbes: Bacillus and L. bacillus spp; Pathogenic fecal microbes: E. coli and Salmonella spp.
