The objective of the present research was to evaluate the addition of cassava bran and corn cob as sources of insoluble fibers in the feeding of laying hens and their effect on productive and zootechnical parameters. The sample used was 300 Hy Line hens of 65 weeks of age. A completely randomized design was applied distributed in six treatments: T0 (control), T1 (1.5% cassava bran), T2 (3% cassava bran), T3 (1.5% corn cob), T4 (3% corn cob) and T5 (mixture of 1.5% of each by-product). They had ten repetitions and five birds per repetition. The analysis of the content of the insoluble fibers Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) and the productive variables weight of the birds, feed consumption, production percentage, egg weight and feed conversion were carried out. The results show that the corn cob has a higher content (ADF) with 53.26% and (NDF) with 12.57%, with reference to the productive parameters; the weight of eggs was higher for T3 in week 3 with 65.33+-0.38, feed consumption and feed conversion decreased significantly in week 3 with 100.18+-2.64 and week 2 with 1.55+-0.04 respectively, while the weight of the hens and the percentage of production were not affected by the inclusion of fibers. It is concluded that the addition of insoluble fibers in the diet of laying hens has been shown to decrease both total feed consumption and feed conversion, so it constitutes an alternative to reduce costs and obtain greater profitability.
