Utilización de tres niveles de harina de Achira (Canna edulis) en la alimentación de pollos Broiler.

Abstract

Achira flour (Canna edulis) was used in the feeding of broiler chicken as an alternative of partial replacement of corn. The experiment was carried out at the farm "Gallegos", in the city of Puyo, Pastaza Province. Achira samples were taken from Patate, Pelileo, Riobamba and Puyo with an approximate weight of a kilo. Four experimental diets were formulated to achira 0, 10, 20 and 30 % addition. For each treatment 50 broiler chickens were used, distributed under a completely randomized design. The feeding phase lasted 42 days. Achira flour provides: metabolizable energy of 3250 Kcal / Kg, determined by reflectance spectroscopy in near infrared (RSNIs), 5 % crude protein (CP), 9.53 % ash (C), 8.16 % fiber (F), 75.26 % starch and 5.84% total sugars . Performance parameters expressed in weight gain and dry matter intake were statistically higher (P < 0.01) in broiler chicken who were fed at of 20% achira with carcass yield of 1529 g and feeding conversion 1.51. The physiological parameters evaluated as: liver, bursa of Fabricius, spleen, guts, had no significant differences (p = 0.05). Including flour achira determined the opportunity to take advantage of a Benefit / Cost 1.60 USD to 20 % of the raw material, showing that it is possible to substitute the ingredients of traditional diets, maintaining a good productive and physiological behavior in broiler chickens. It is recommended to test the inclusion of achira as food for other species such as guinea pigs, rabbits, pigs, horses and cattle.
