SOUSA, J.P.L. et al. Cassava bagasse in broiler diets with or without addition of enzyme complex. Arch. zootec. [online]. 2014, vol.63, n.244, pp.657-664. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922014000400009.

The present work was conducted to evaluate the use of cassava bagasse (BM) in rations with enzyme complex (CE) as supplement for broilers in two phases. Two experiments were conducted to assess the weight gain (GP), feed intake (CR) and feed conversion (CA) in the phases 1-21 and 22-40 days of age, of broilers receiving diets containing 0 and 20 % of BM and, with or without CE. The experiments were conducted in a completely randomized block design with 8 replicates and 20 broiler per experimental unit using a 2x2 factorial arrangement (0 and 20 % of BM, with or without CE). There was no interaction between treatments, inclusion of BM and CE. The inclusion of BM decreased CR and GP in both phases. Whereas the inclusion of CE improved GP and CA at the initial stage did not affect the performance at 22-40 days of age, the cost of feed per kilogram of weight gain was lower and the rates of economic efficiency and cost for both phases was better in animals subjected to diets with 0 % of cassava bagasse inclusion with the enzymatic complex.
