- Abstract
Introduction: Cajanus sp and Mucuna sp are legumes used in human and animal feed, as a cover crop, fertilizer and as medicinal plants. Aim: To evaluate the effect of cooking and roasting applied to raw grains of Cajanus sp and Mucuna sp. Methods: Cajanus sp and Mucuna sp grains with two levels of inclusion (10% and 20%) were added to reference diets (RD) of corn and soy cake. Apparent metabolizable energy was measured with nitrogen balance correction (EMAn) in Ross 308 line chickens with 21 days of age, by the technique of replacing the energy core of the RD and total collection of excreta. Results: The raw grain of Cajanus sp presented a value of 2286.2 kcal of EMAn/kg of dry matter (DM) that was lower than roasted grain (2945.5 kcal) and cooked grain (3115.9 kcal). Regarding the effect of the level of inclusion, the EMAn of the grain decreased by 601.1 kcal/kg of DM from 10% (3072.8 kcal / kg of DM) to 20% (2471.7 kcal/kg of DM). In theMucuna sp bean only the level of inclusion in the RD affected the EMAn. When 10% of this grain was included, it presented a value of 2432.3 kcal/kg DM and decreased to 1938.1 kcal with 20%. The EMAn values of raw, roasted and cooked grain were 1923.1, 2178.0 and 2387.2 kcal / kg DM, respectively. Conclusions: In this type of food resources the value of the EMAn was different depending on the thermal process applied to the beans, but in both grains this value decreased as its level of inclusion increased in the RD.
