Table 1. Physiological effects of chronic CORT treatment.
LMEs for body mass, hematocrit (Ht %), redox state markers (TAS—total antioxidant status, UA—uric acid, tGSH—total glutathione, MDA—malondialdehyde; for residual TAS, see Methods) and coccidian infestation, and GLMMs for innate immunity variables (natural antibodies [NAbs] by hemagglutination score and complement by hemolysis scores). Degrees of freedom are 1 for treatment and 3 for sampling and treatment × sampling throughout. Significant effects are marked in boldface and marginally significant effects (0.05 < P ≤ 0.10) in italic.
