* Base diet; ZnO: base + 3 g ZnO/kg; OACP: base + 1.5 g/kg of a mixture of an organic acid blend, cinnamaldehyde and a permeabilizing complex (Biotronic Top 3^®, Biomin Australia Pty, Ltd., Carlingford, Australia); ^† Data not normally distributed were logarithmically transformed then analysed by GML. Values were back-transformed and expressed as least square means with 95% confidence intervals (in brackets); ^‡ Specific E. coli used for oral infection in the experiment; SEM, standard error of the mean; D, day; T, treatment.
