In trial 1, four experimental diets were formulated to contain 0, 500, 1000, and 2000 ug kg-1 of total aflatoxins (TA) and fed to L. vannamei juveniles for 28 days.

| description | Two feeding trials were carried out to evaluate the effect of diets containing corn or peanut grains naturally contaminated with aflatoxins on the growth, feed intake, survival, and histological response of the white shrimp Litopenaeus vannamei. In trial 1, four experimental diets were formulated to contain 0, 500, 1000, and 2000 µg kg–1 of total aflatoxins (TA) and fed to L. vannamei juveniles for 28 days. In trial 2, six experimental diets were formulated to contain 0, 10, 20, 40, 60, and 120 µg kg–1 TA and fed to L. vannamei juveniles for 64 days. Feed intake and weight gain were significantly affected by the presence of aflatoxins from naturally contaminated grains. Feed conversion rate increased significantly from a level of inclusion of 60 µg kg–1. Survival was significantly reduced only for shrimp fed diets supplemented with 1000 and 2000 µg kg–1 TA. Shrimp exposed to higher aflatoxin inclusion levels presented significantly lower lipid vacuole levels in R-cells (12–28%), lower B-cell activity, and lower mitotic E-cell activity. Tubular epithelial atrophy increased from the inclusion level of 20 µg kg–1. Hepatopancreatocyte sloughing was significantly higher in shrimp fed diets supplemented with 1000 and 2000 µg kg–1 TA. It is worth noting that shrimp fed 40 µg kg–1 TA presented a high hepatopancreatocyte sloughing coefficient. Based on these results we conclude that the presence of aflatoxins, even at low levels, reduces feed intake and weight gain, and alters the cells of the hepatopancreas.
Se llevaron a cabo dos bioensayos para evaluar el efecto de granos de maíz y maní contaminados naturalmente con aflatoxinas sobre el crecimiento, consumo de alimento, supervivencia y daños histológicos de juveniles del camarón blanco Litopenaeus vannamei. Para el bioensayo 1, se formularon cuatro dietas con 0, 500, 1000 y 2000 µg kg–1 de aflatoxinas totales (AT) y se proporcionaron a juveniles de L. vannamei durante 28 días. Para el bioensayo 2, se formularon seis dietas con 0, 10, 20, 40, 60 y 120 µg kg–1 AT y se proporcionaron a juveniles de L. vannamei durante 64 días. El consumo de alimento fue significativamente afectado por la presencia de aflatoxinas. La tasa de conversión alimenticia incrementó significativamente a partir de un nivel de inclusión de 60 µg kg–1. La supervivencia fue significativamente reducida solamente en los camarones que fueron alimentados con las dietas suplementadas con 1000 y 2000 µg kg–1 AT. Los camarones expuestos a los niveles de inclusión altos presentaron un menor nivel de vacuolas lipídicas en las células R (12–28%), y una menor actividad de las células B y de la actividad mitótica de las células E. La atrofia de los túbulos del epitelio se incrementó a partir de un nivel de inclusión de 20 µg kg–1. La descamación de las células del hepatopáncreas fue significativamente mayor en camarones alimentados con las dietas suplementadas con 1000 y 2000 µg kg–1 AT, mientras que para las dosis bajas no se observaron diferencias significativas, aunque en camarones alimentados a partir de 40 µg kg–1 AT se observa un coeficiente de descamación alto. Con base en los resultados, se concluye que la presencia de aflatoxinas, incluso a niveles bajos, reduce el consumo de alimento y el aumento de peso y altera las células del hepatopáncreas. |
