    Nutrient digestibility allows to optimize and improve feed conversion and productive performance in birds, so there is a need to evaluate food alternatives that cover their nutritional requirements. The general objective of the following research was to determine the nutrient digestibility in broiler chickens fed with different sources of fiber. For the development of the research, 64 chickens of the Cobb 500 line of 42 days of age were used, with an average weight of 7075 g, they were randomly assigned to four treatments including different sources of fiber T1: control, T2: 18% wheat bran, T3: 18% rice husk and T4: 18% palm kernel. The diets were formulated considering the nutritional requirements of the Cobb 500 chicken line. A completely randomized design was applied. The variables studied were dry matter digestibility, organic matter, crude fiber, crude fat, crude protein. The data were analyzed in the statistical package Infostat by means of a variance analysis, in which the fiber sources were taken as the main variation factors and the Tukey test was used to compare means. The results presented statistical differences, p < 0,05 for dry matter, organic matter and crude fiber, showing a higher percentage of digestibility with the inclusion of 5% of wheat bran with 80.3; 67.00; 15.06% respectively; while for crude protein p = 0.181 and crude fat p = 0.281, there was no difference between treatments. It is concluded that the inclusion of fiber sources in the diet of broilers shows acceptable nutrient digestibility percentages.
