This investigation was conducted in the rural community of Cuambo, located in the northeast of the province of Imbabura, in the Mira river basin of Salinas parish, at 1530 meters above sea level and with an average temperature of 19.5° C. The main objective of this investigation was to analyze the effect of using amaranth (Amaranthus) leaf flour in the creation of feeds for broiler chickens. The field work occurred during 12 months and consisted of two phases: A. Creation of the feed: This proceeded from the cultivation, cutting, and drying of amaranth until the obtaining of the flour and later the feed, with the respective formulation and acquisition of primary materials. B. Broiler chicken production: This occurred in the coop of the community's school, previously prepared for taking in the chicks. The study lasted 8 weeks. A completely random design (CRD) with five treatments and four repetitions per treatment was used, with 10 chickens per experimental unit. ANOVA analysis and Tukey and orthogonal comparisons were applied. The factor under study was the percentage of amaranth leaf flour in a basic diet. The treatments were as follows: T0 = Control diet for broiler chickens T1 = 16.7% amaranth leaf flour T2 = 35% amaranth leaf flour T3 = 54% amaranth leaf flour T4 = 78% amaranth leaf flour Analyzed variables: Weekly weight increase, Weekly food conversion, Accumulated food conversion, Total food consumption, Efficiency index, Yield, Skin pigmentation at the end of the treatments, Organoleptic analysis, Mortality, Economic analysis. From the results obtained, we conclude that the feed from treatment 1 (T1) is the best because it gave the most efficient results in terms of weight increase, food conversion, efficiency index, yield, and production cost. In the organoleptic analysis, T2 received more points regarding appearance, color, and texture; T1 received the best points in odor. The most acceptable treatments are T2 and T1, with the most points. In production cost, T4 was the least expensive, but it is not recommended for use because the chickens had poor results in the studied variables.
