    Current poultry production faces constant challenges due to the economic fluctuation of traditional raw materials such as corn and soybean meal. This research project was carried out in Tanicuchí parish, Cotopaxi province, with the objective of evaluating the effect of including three levels of alfarina (alfalfa meal) (5%, 10%, and 15%) in the diet of Cobb 500 broiler chickens. The bromatological characterization performed at the Laboratory determined that the forage possesses 19.77% crude protein, 29.77% crude fiber, and 89.87% dry matter. For the biological trial, a Completely Randomized Design (CRD) was used with 100 birds distributed into four treatments (T0: Control, T1: 5%, T2: 10%, and T3: 15%), with 5 replicates of 5 birds each. Statistical monitoring through repeated-measures ANOVA determined that alfarina did not significantly depress the weight gain of the batches (p = 0.836). By day 41 of the cycle, treatment T2 (10%) reported the most efficient zootechnical performance with an average body weight of 1,671.94 ± 208.35 grams, an optimal final weekly weight gain dynamic (p = 0.023), and the best financial viability according to the benefit/cost ratio. In conclusion, alfarina qualifies as a functional and safe prebiotic additive for local intensive poultry farming.
