Fig. 1. Schematic illustration of the experimental design. One-day-old Cobb, Hubbard, and Ross chickens were fed a standard unsupplemented diet or a diet supplemented with a mixture
of Capsicum/Curcuma longa oleoresins (XT). The diet contained 17% protein and 61% carbohydrate between days 1 and 14 and 24% protein and 54% carbohydrate between days 15 and 20.
Chickenswere infected by oral gavage with E.maxima at day 14 and C. perfringens at day 18. At day 20, bodyweights and lesion scoresweremeasured and the intestinal ileumwas sampled
for microbiome analysis
