Items, log10cfu/g	CON	TRT1	TRT2	SEM	p-value
CB	6.36	6.30	6.19	0.03	0.087
LAB	9.40	9.50	9.62	0.03	0.070

CON, basal diet; TRT1, basal diet + 3,000 ppm ZnO; TRT2, basal diet + 750 ppm Zn-Asp.
Means in the equivalent row show the superscripts differ (p < 0.05).
CB, coliform bacteria; LAB, lactic acid bacteria.
