Variables ²	CON	AT	BA	AL-L	AL-H	BA+AL-H	SEM	p Value
Total bacteria	12.85	12.85	13.15	13.11	13.01	13.11	0.22	0.544
E. coli	10.29 ^a	9.67 ^ab	9.33 ^ab	9.66 ^ab	9.84 ^ab	8.93 ^b	0.46	0.041
Enterococcus	7.94 ^ab	7.59 ^ab	7.75 ^ab	8.37 ^a	7.44 ^b	7.80 ^ab	0.34	0.026
Lactobacillus	11.18 ^b	11.69 ^a	11.69 ^a	11.80 ^a	11.61 ^ab	11.71 ^a	0.27	0.008

¹ Values are means of 12 birds with 2 birds per replicate. ² Data are log10(CFU)/g. ^ab Mean value within a role with no common superscript differ significantly (p < 0.05). CON = the control group, AT = the antibiotic (zinc bacitracin), BA = benzoic acid, AL-H = high level amylase, AL-H = high level amylase, AL-L = low level amylase. SEM = standard error; E. coli = Escherichia coli.
