    The objective of this study was to analyze different percentages of cinnamon flour addition in broiler chicken diets, with 0.05%, 0.075% and 0.1% being evaluated, and their effects on production indices and cost/cost ratio. benefit of different treatments. Four different treatments were studied, including a control with 0% cinnamon flour. For this work, a completely randomized statistical design was carried out, which consists of three repetitions for each treatment applied, which presented 10 experimental units adding up to a total of 120 chickens. The analysis of the means was performed using Tukey's statistical test at 95% reliability. It was divided into three stages of productive period, initial (0-7 days), growth (8-21 days), and fattening (22- 35 days). It was concluded that in the different stages, it was established that the best treatment was T3, on day 28 with greater weights in the spleen (1.3 g), bursa (2.2 g) and thymus (4.4 g), with respect to on day 35, there are no statistically significant differences between the treatments, and regarding the cumulative analysis, differences were obtained in terms of final weight and European deficiency index, with the most viable treatment being T3 with the addition of 0.1% cinnamon flour. by presenting good productive performance and a cost/benefit ratio of 1.4 points. Keywords: broiler chickens, cinnamon flour, production indices.
