    This research study was carried out to evaluate the effect of the partial substitution of banana flour and cocoa husk flour in the diet of broiler chickens. Ninety-six Cobb 500-line chickens, 14 days old, were randomly distributed into three treatments with 32 birds each. Six productive variables were evaluated by using analysis of variance (ANOVA) and Duncan's test. Bromatological, microbiological, and physical analysis of the by-products used in this research study were made. The results were acceptable in terms of protein percentages, with 9.05% in cocoa husk flour and 2.41% in banana flour. Microbiological analysis confirmed the absence of pathogens in both by-products, which could not affect the project, with an average particle size of 190 µm and 220 µm for cocoa husk and banana flour, respectively. The research study did not show significant differences in average weight at the end of the methodological phase, although T2 showed the highest average weight of 2487.8 g, with a feed conversion ratio of 1.65, and the lowest weight for T0 at 2292 g in the fourth week. The T2 carcass yield was 72.40%. In terms of profitability, the partial substitution with these by-products resulted in a better cost/benefit ratio, especially in T2, which had a profit of 0.28 cents, followed by T1 with 0.16 cents per dollar, suggesting that the use of these by-products could be the most effective and economical option for poultry producers, thus providing better profitability for small and medium-sized poultry farmers, allowing them to be more competitive in the poultry industry.
