MOSQUERA, MARI L; PORTILLA, SANDRA  e  LOPEZ, FREDY J. NUTRITIONAL EFFECT EVALUATION OF QUINOA (Chenopodium quinoa willdenow)) WITH DIFFERENT LEVELS OF INCLUSION IN DIETS FOR BROILER CHICKENS. Rev.Bio.Agro [online]. 2009, vol.7, n.1, pp.76-90. ISSN 1692-3561.

128 male chickens Ross 308 were used, of a day of age to evaluate the effect of different levels of inclusion from quinoa, for which a design completely at random was implemented, with four treatments (T0 commercial concentrate; T1 5% of quinoa; T2 15% of quinoa and T3 with 25% of quinoa), four repetitions by treatment and 8 birds by repetition, with the purpose to determine the behavior between variable food intake, weight gain, feed conversion, nutritional efficiency, and yields carcass, in the stages of initiation and conclusion. The results were put under an analysis of variance and a test of multiple comparison Duncan. Significant differences (p<0.05) for the variables of food intake, feed conversion and nutritional efficiency at the initiation stage were observed; and also, significant differences for the indicators of feed conversion, nutritional efficiency and yields carcass, in the stage of conclusion were observed; on the other hand, differences for the variable weight gain in the two productive stages were not observed. From the economic point of view, the treatment with 5% of inclusion of quinoa represents the greater yield being a 116% superior to the treatment control, obtaining productive yields similar to the obtained ones with a commercial concentrated but a lower cost. In general terms, quinoa contributes an important level of nutrients that allows to generate an acceptable productive behavior in broiler chickens.
