    The use of agro-industrial byproducts represents a sustainable alternative for poultry production. Therefore, this research aimed to evaluate the use of natural probiotics obtained from pineapple peel (Ananas comosus) and banana peel (Musa paradisiaca), through their administration in drinking water and their effect on the productive performance of broiler chickens. The study was developed under a quantitative, of type experimental approach, with a completely randomized design (DCA), using four treatments: T0 (control without inclusion of probiotic ferment), T1 (5 ml of pineapple peel ferment), T2 (5 ml of banana peel ferment), and T3 (mixture of both ferments, 2.5 of each, respectively), with 25 birds per treatment and a total of 100 broiler chickens, during a period of 42 days. Physicochemical, bromatological, and microbiological analyses of the starters were performed, in addition to the evaluation of live weight, feed consumption, water consumption, weight gain, feed conversion, and cost/benefit analysis. The fermented beverages showed acidic pH (3.51 in pineapple peel and 3.77 in banana peel), soluble solids of 3.28 and 3.49 °Brix, respectively, reducing sugars of 12.83% and 15.21%, moisture content greater than 92%, acetic acid of 3.11 and 3.43 g/L, and ash of 0.55% and 1.23%. Furthermore, presented viable beneficial microorganisms, notably Lactobacillus spp., Bacillus subtilis, and Saccharomyces cerevisiae, at concentrations of 10^6 CFU/mL. Regarding productive performance, supplementation with the fermented beverages did not result in statistically significant differences in live weight, water consumption, feed consumption, or feed conversion during most of the experiment. Weight gain only showed a significant difference at 28 days; however, treatment T3 reached the highest value; however, this effect was not maintained in subsequent evaluations. Mortality was low, with only one death in treatment T2, and the overall viability of the batch remained high. In the economic analysis, all treatments showed a benefit-cost ratio greater than 1, with the control treatment being the most profitable (1.23), while the treatments with fermented products registered values of 1.20, demonstrating that the inclusion of these natural probiotics did not improve profitability compared to the control treatment. These findings indicate that fermented pineapple peel and banana peel beverages have suitable characteristics for use as a natural probiotic supplement, but their inclusion under the evaluated conditions did not produce a consistent improvement in the productive performance or profitability of the broiler chickens.
