Effects of Dietary Chicory ( L.) and Probiotic Blend as Natural Feed Additives on Performance Traits, Blood Biochemistry, and Gut Microbiota of Broiler Chickens.

The experiment was designed to determine the effect of different levels of chicory ( L.) powder and a probiotic blend (PrimaLac) on productive performance, blood biochemical parameters, and ileal microbiota in broiler chickens. A total of 225 one-day-old broilers (Ross 308) were used in a completely randomized design with five experimental diets as follows: 1-basal-diet without supplements (control-group); 2-basal-diet including probiotic blend; 3- basal-diet including 0.
