¹All means are average of 20 (2 x culture plates/treatment). Campylobacter spp. cultured on CCDA medium, E. coli cultured on chromogenic agar; CFU = colony forming unit; SEM = standard error of the mean; T₁ = Control; T₂ = 0.02 g/kg TYPLEX^® Chelate; T₃ = 0.05 g/kg TYPLEX^® Chelate; T₄ = 0.20 g/kg TYPLEX^® Chelate.

²Significant level (P ≤ 0.05).
