a,bMeans in a column within type of variable and main effect or interaction treatment with no common superscript differ significantly (P ≤ 0.05).

Abbreviation: woa, wk of age.

1

Main effect means based on 4 birds in each of 16 units in each dietary treatment group across challenge treatment (64 total birds).

2

Main effect means based on 4 birds in each of 16 units in each challenge treatment group across dietary treatment (64 total birds).

3

Interaction effect means based on 4 birds in each of 8 replicate units in each diet-challenge treatment combination group (32 total birds).
