Values of each row are mean and standard error of 12 birds of a trial group (n = Number of birds of a trial group examined for each test). Mean values in the same row with different letters differ significantly (p < 0.05). *Indicates significant variation (p < 0.05) within a row. TCpC = Total Clostridium perfringens count, TSC = Total Salmonella count, TEC = Total E. coli count, TBC = Total Bacillus count, TBlC = Total Bacillus licheniformis count, TBsC = Total Bacillus subtilis count. ² SEM= Standard error of mean
