Se evaluaron la seguridad y efectividad de cuatro productos a base de aluminosilicatos (Novasil Plus, Zeolex Extra, Mycofix Select y Fixat) durante 42 días en juveniles de camarón blanco del Pacífico, Litopenaeus vannamei, alimentados con granos de maíz que habían sido previamente inoculados con Aspergillus parasiticus y después esterilizados. Dos dietas control, una no contaminada y otra contaminada con el grano de maíz inoculado, fueron elaboradas para contener una concentración de 0 y 75 μg kg–1 de aflatoxinas totales. Ambas dietas fueron formuladas para contener 38% de proteína cruda y 8% de lípidos crudos. Ocho dietas más fueron elaboradas a partir de las dos dietas controles para contener cada uno de los productos a evaluar a un nivel de inclusión de 2.5 a 5.0 g kg–1, siguiendo las recomendaciones del productor. La inclusión de Mycofix Select y Fixat mejoró la estabilidad de las dietas (12–16%). La capacidad de absorción de agua de las dietas se incrementó (de 2% a 17%) debido a la suplementación de aluminosilicatos. Las dietas contaminadas con aflatoxinas disminuyeron el consumo de alimento y el aumento de peso sin afectar la tasa de conversión alimenticia, la eficiencia de retención de nitrógeno y la supervivencia de los camarones. La alimentación con las dietas no contaminadas suplementadas con Zeolex Extra, Mycofix Select y Fixat redujo ligeramente el consumo de alimento sin decremento de la tasa de crecimiento, la eficiencia de retención de nitrógeno y la supervivencia. En cambio, la inclusión de Novasil Plus en la dieta no contaminada no afectó el consumo de alimento y mejoró la tasa de crecimiento en un 8%. Tres de los productos evaluados no proporcionaron una restauración completa del consumo de alimento y la tasa de crecimiento cuando fueron suplementados a una dieta contaminada con aflatoxinas. |
