--- This study compared the main productive parameters of broilers supplemented with growthpromoting activity anticlostridial diet, developed on the facilities of the Faculty of Veterinary Medicine of the Universidad Nacional Mayor de San Marcos, Lima-Peru. 575 birds divided into 5 groups of 115 animals with 5 repetitions each were used. Group G1 was challenged and treated with encapsulated lysozyme, G2 was challenged and treated with phytobiotics (Humulus lupulus), G3 was challenged and treated with zinc bacitracin, G4 was the positive control without promoter and challenged and G5 was the negative control without promoter and unchallenged. Two challenges with Eimeria oral and drinking water (14 to 22 days) and Clostridium perfringens challenge (108 CFU / mL) at 26 days oral route were performed. The results showed that birds of G1 and G2 were 56 and 42 g of body weight more than G4. The greater weight gain average was obtained by G2 (2570.82 g). G4 had the highest cumulative consumption introduced (4797.82 g), G1 the lowest (4676.12 g). G1 the best feed conversion (1.78), followed by G2 (1.79) .The European productive efficiency index showed a better efficiency for G1 (349.16) Comparing G1 and G2 against G3, obtained 4.65% and 3.60% over respectively production efficiency. However, analysis of variance of the production parameters (average weight, weight gain, feed conversion rate, feed intake and European efficiency index) in the five study groups showed no significant difference between them (p> 0.05). The results suggest that supplementation with alternative products such as Bacitracin Zinc and phytobiotics encapsulated lysozyme (Humulus lupulus) improve the productive performance of broiler chickens under clostridia challenging conditions. Keywords: growth promoter, Clostridium perfringens, production parameters, broilers.
