Poultry production has major challenges to streamline animal productivity, improve intestinal health, create safe and of good nutritional quality protein for human consumption. Plant diversity of Colombian tropical plant species has not evaluated in animal feed and which may have beneficial antiseptic properties in the productive parameters and intestinal health of chickens. The aim of this study was to evaluate the inclusion of the leaves of two plants from Choco, Santa Maria (Piper peltatum) and basil (Ocimum basilicum) on performance of broilers Ross 308 line in Colombia. The experiment was conducted in the San José de Guausa farm, located in the municipality of Chia, Cundinamarca Department. Two hundred chickens Ross 308 commercial line a day were used. Birds were evaluated for an experimental of 42 d. Four treatments were evaluated. Control (CON, basal diet): animals were fed a diet of corn-soybean meal without aromatics plants; treatment two, animals that received the control diet with the inclusion of 0.05% basil leaves (ABH); treatment three, animals fed with 0.05% leaves of Santa Maria (SMB) and treatment four diet by including 0.025% (ABH) and 0.025% (SMB). The production parameters evaluated were feed intake (g), weekly weight (g), feed conversion and weight gain (g). The experimental design was completely random, distributed in four treatments, five replicates per treatment, and 10 animals per repetition. Data variables were asked ANOVA, and to detect between treatment means the Tukey test was employed in the SAS statistical package. As a result of this study, significant difference (p < 0.05) was found between treatments for the weekly weight, bird average daily gain and feed conversion, ABH was the treatment with the best results in week seven for the weight (2362 vs. 2155, 2297, 2346 g), weight gain (79 vs. 59, 71, and 76 g) and feed conversion (2.079 vs. 2.23, 2.42, 3.74). These results suggest that the diet with the addition of 0.05% of ABH can benefit the productive parameters of chickens level weight, weight gain and feed conversion, which favors animal productivity.
