Table 8.

Mean blood calcium (Ca2+), potassium, (K+), sodium (Na+), and chloride (Cl−) values at 12 woa in birds after a RlowMycoplasma gallisepticum (RlowMG) challenge at 8 and 10 woa and that belonged to basal (control) and XPC-supplemented (XPC) dietary treatment groups.

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).
