The purpose of this research is to investigate garlic powder, turmeric powder and Saccharomyces cerevisiae (SC) yeast extract (Thalizyme®) and common probiotic to reduce the consumption of antibiotics on the growth performance, morphology, intestinal microflora and immune response of broilers. In order to conduct this research, 320 one-day-old male broiler chickens of Ross 308 strain.This design was implemented in the form of a completely randomized design with 8 different experimental treatments, which were considered 4 replications for each experimental treatment, and in each replication (cage), 10 chickens were placed randomly. The treatments were: 1) control (basal diet) treatment, 2) basal diet + garlic powder at the rate of 0.3%, 3) basal diet + turmeric powder at the rate of 0.75% , 4) basal diet + Saccharomyces cerevisiae yeast extract at the rate of 0.5% recommended by Taligene Pars Company, 5) basal diet + Parsilact probiotic, 6) basal diet + garlic powder at the rate of 0.3% + turmeric powder at the rate of 75 0.0%, 7) basal diet + garlic powder at 0.3% + turmeric powder at 0.75% + Talizyme®0.5%, 8) basal diet + garlic powder at 0.3% + powder Turmeric 0.75% + Thalizyme® yeast extract 0.5% + Parsilact probiotic. Based on the results of this research, overall it can be concluded that the dietary feed additives used in this study improved feed conversion ratio, carcass characteristics, and decreased harmful and increased beneficial intestinal bacteria population, and improved immune indicators in broiler chickens.
