TABLE 2.
The main effect of time, treatment, and the interaction of treatment × time on the prevalence of overall Salmonella when inoculated into an in vitro turkey cecal model with and without Original XPCTM at 0, 24, and 48 h post inoculation (hpi) over two trials.

1Main effect of time: P < 0.0001, n = 40, N = 120, k = 3, Pooled SEM = 4.79.
2Those with different superscripts (a–b) are significantly different from one another (P < 0.05).
3Main effect of treatment: P < 0.0001, n = 60, N = 120, k = 2, Pooled SEM = 3.86.
4Those with different superscripts (a–b) are significantly different from one another (P < 0.05).
5Interaction of Treatment and Time: P < 0.0001, n = 20, N = 120, k = 6, Pooled SEM = 6.69.
6Those with different superscripts (a–c) are significantly different from one another (P < 0.05).
There was a trend in the effect of Salmonella serovars (P = 0.07, n = 60, N = 120).
