The aim of this study was to evaluate the effects of quinoa seed–based diets with phytase and protease enzymes, individually or in combination, on the productive performance, internal organs, microbiota activity, and intestinal morphology of broiler chickens. A total of 250 1-day-old broiler chicks (ROSS 308) were randomly distributed into five treatments with each five replicate pens of 10 birds in a 42-day trial. Dietary treatments were a conventional diet (CC) based on a corn-soybean meal or an experimental diet (EC) which contained 150 g/kg of quinoa seed. Other treatments were EC diet supplemented with 500 FTU/kg phytase (EPH), 0.2 g/kg protease (EPR) enzymes, or their combination (EPPC). At the end of the trial, the feed intake of the EPH broilers was higher than those of the EC and EPPC birds ( P
