Figure 2.
Effect of dietary zinc (Zn) and challenge (C) on fecal shedding of (A) ETEC F18, (B) LT toxin, and C) STb toxin on days (D) 0, 3, 5, 7, and 14 (n = 12). Estimated marginal means with 95% confidence intervals are shown. abIndicate difference (P ≤ 0.05) between Zn concentrations within challenge group and day. xyIndicate difference (P ≤ 0.05) between challenge groups within Zn concentration and day. The comparison between days within the Zn concentration and challenge group is deliberately not shown to increase the readability of the figure.
