Background: flavophospholipol is an antibiotic growth promoter (AGP). The current ban of AGP in some countries is controversial because their benefits on the environment and economy by saving feed and reducing nitrogen excretion have been overlooked. White button mushrooms have important nutritional properties and the industry discards large quantities of waste that could be fed to animals. Objective: to evaluate the effect of dietary inclusion of five levels of edible mushroom powder (EMP) and flavophospholipol on the performance and blood serum metabolites of broilers. Methods: a total of 300 one-day-old male broiler chicks were randomly distributed into 10 treatments with three replicates of 10 chicks per pen. The experiment consisted of a factorial arrangement (2x5 treatments) with five inclusion levels of EMP supplementation (0, 0.5, 1.0, 1.5, and 2.0 g/kg of diet) and the addition of 0 or 5 mg/kg of flavophospholipol. Results: supplementation with EMP and flavophospholipol, as individual factors, had a negative effect on feed intake, but positively affected broiler weight gains and feed conversion ratio. Antibiotic supplementation increased uric acid concentration and, as an interaction with mushroom powder, reduced serum triglycerides, and very low density lipoprotein cholesterol (VLDL). The EMP also affected serum concentration of total cholesterol. Conclusion: the two substances studied, but not their combination, had a positive effect on growth performance of chickens that could be translated into economic benefits.
