The feeding represents most of the total cost of production and to reduce costs and increase the profit of the producer have been researched alternative food, as the pie of babassu palm, the pie of palm and the cassava bagasse, which show potential for usein feeding the chickens for slow growth, however, with limited use, due to the different grades of fiber. Non-starch polysaccharides make it difficult for digestible enzymes to reach the food, reducing the digestibility of nutrients. To minimize this effect, exogenous enzymes have been supplemented in DOI: http://dx.doi.org/10.20873/uft.2359-3652.2017v4n2p35Revista Desafios –v. 04,n. 02, 201736poultry diets. Various sources can originate these additives, most of which are acquired through fermentation processes. The temperature, pH, substrate concentration and composition of the ingredients are factors that influence the enzymatic action and consequently the availability of the nutrients. Studies show that the use of fungal enzymes can increase the nutritional value of the food and improves the digestibility of nutrients, reflecting the productive efficiency, representing savings in production costs and benefits to the environment, however, it is necessary to evaluate the use in diets with alternative foods of Regional expression.
