Resumen

El objetivo del estudio fue evaluar en dietas de pollos, el valor alimenticio de la mezcla de harina de germen de maíz (HGM) en 50% y la adición de 50 % de licor de maíz (LM) sin y con enzimas carbohidrasas (CH) y la fermentación durante 24 horas. Se realizó un ensayo con el LM + enzimas para Polisacáridos no amiláceos (PNA) y LM con fermentación por 24 h. Se utilizaron 240 pollos machos Ross 708, de 6 a 50 días de edad alimentados con dietas base maíz + pasta de soya (iniciación, crecimiento y finalización), con 5, 10 y 20 % de HGM, con la inclusión de diferentes presentaciones de LM (0 % LM, LM natural y LM fermentado) en porcentajes iguales a los de HGM sin y con enzimas carbohidrasas (103 000 U/g de xilanasas, 128 000 U/g de celulasas y 33 000 U/g de beta-glucanasas) a 25 ppm. La ganancia de peso de los pollos de 6 a 50 días de edad mejoró 5 % (P<0.05) con la adición de LM natural al HGM. La combinación HGM + LM natural, incrementó el valor alimenticio en dietas para pollo de engorda. La adición de enzimas en dietas con HGM+LM natural no afectaron el comportamiento productivo de los pollos.
