The poultry industry is looking for alternatives that can replace antibiotic growth promoters (AGPs). The objective of the present study was to evaluate the effect of supplementation of a mixture of probiotics, prebiotics, enzymes and minerals compared to AGP in the diet of broiler chickens, on productive performance, intestinal morphometry and economic retribution. 200 male chickens of the Cobb 500 line were used, randomly distributed in four treatments with five repetitions and ten birds per experimental unit. The treatments were: control diet (T1), control diet plus AGP: zinc bacitracin (0.05%) and colistin (0.03%) (T2), control diet plus the mixture of probiotics, prebiotics, enzymes and minerals at 300g/ton (T3) and at 500 gr/ton (T4). Food was supplied ad libitum in the form of flour, using four phases: start (1-8 days), growth (9-18 days), finisher 1 (19-28 days) and finisher 2 (29-42 days). The results showed that at 42 days there were no significant differences (p>0.05) in the productive parameters when comparing the evaluated mixture (T3 and T4) with the APC treatment (T2). However, better significant values (p<0.05) were found in final weight, weight gain and feed conversion in favor of T3 compared to the control (T1). In intestinal morphometry, there was only a significant difference (p<0.05) in villus height, with T3 being greater than treatment with APC (T2). T3 generated the highest economic reward (8%) compared to the other treatments. It is concluded that the supplementation of the mixture of probiotics, prebiotics, enzymes and minerals at 300g/ton evaluated in this study can be considered a viable alternative to the use of AGPs, since it has a better effect on hair height, thus achieving similar results in productive parameters and greater economic remuneration.
