Resumen

la contaminación de la cebada con micotoxinas de Fusarium causa importantes pérdidas económicas para los productores de carne de cerdo, pero adsorbentes de micotoxinas para prevenir los efectos perjudiciales de las micotoxinas no dieron resultados consistentes. Objetivo: evaluar el producto de la pared celular de la levadura en la prevención de los efectos adversos de las micotoxinas de Fusarium sobre el crecimiento, características de la sangre, y la digestibilidad de nutrientes en cerdas jóvenes alimentadas con dietas que contienen cebada naturalmente contaminada con micotoxinas de Fusarium. Métodos: se prepararon las dietas a base de harina de maíz-soja de control positivo y negativo contienen 20% de control y cebada contaminados con micotoxinas de Fusarium, respectivamente. Adicionalmente se prepararon 2 dietas con productos de la pared celular de levadura de 0,2 o 0,4% a la dieta de control negativo. Fueron alimentados con las dietas experimentales cerdos con un peso corporal inicial de 61,7 Kg durante 2 semanas. Resultados: los cerdos alimentados con la dieta control negativo ganaron menos que aquellos alimentados con la dieta control positivo (p < 0,05) a partir del d 0 a 7 y durante el período en general, pero la digestibilidad de los nutrientes y características de la sangre no fueron afectados por la alimentación de la dieta contaminada. La mayoría de las mediciones no fueron afectadas por la suplementación de la pared celular de la levadura con la dieta control negativo. Conclusión: la adición del producto de pared celular de levadura a la dieta control negativo no logró aminorar los efectos adversos de las micotoxinas de Fusarium sobre el crecimiento.
