In Valparaiso, Caqueta, Colombia, an investigation was carried out with the aim of evaluating the effect of replacing part of commercial concentrates with a meal made of 67.49% of Trichanthera gigantea, 7.65% Tithonia diversifolia, 11.91% Saccharum spp., 11.99% Alocasia macrorrhiza and 0.96% Musa paradisiaca in broiler chickens. Using 48 chickens of the Ross strain, which formed an experimental unit with four chickens for cage, randomly divided into four treatments with three replicates for treatment, thus: T0 = 100% concentrates; T1 = 25% replacement of the concentrates; T2 = 50% replacement, and T3 = 75% replacement. Three replications per treatment were used. There were no significant differences (P < 0.05) in food consumption between T0 and T1, and for carcass yield between T0, T1 and T2. Average daily gain and feed conversion where significantly different (P < 0.05) in all the treatments. The skin pigmentation was more yellowish in treatment T3. Replacement of 25% of the concentrate showed a higher benefit cost ratio of 6.87%, 18.24% and 77.95% at T0, T2 and T3 respectively.
