摘要：
This study aimed to investigate if myo-inositol (MI) supplementation could alleviate adverse effects caused by aflatoxin B-1 (AFB(1)) with respect to growth performance, AFB(1) residues, immune response and antioxidant status of Litopenaeus vannamei. 800 shrimp (initial weight: 1.1 g) were divided into five groups: MI0 (basal diet); MI0 + LA, MI0 + HA, MI200 + LA and MI200 + HA fed with AFB(1)-contaminated diets (LA, low concentration AFB(1); HA, high concentration AFB(1); MI200, adding 200 mg MI kg(-1) diet). The results showed that HA significantly decreased growth performance, systemic inositol content and lipid content. AFB(1) residues were detected in the hepatopancreas of shrimp, but not the muscle. Histological lesions were observed in MI0 + LA and MI0 + HA groups. HA supplementation raised malondialdehyde and protein carbonyl content and reduced some antioxidant enzyme activities and immune-related genes expression, which was slightly ameliorated by MI supplementation. Our results suggest that myo-inositol may slightly mitigate negative impacts caused by AFB(1) in L. vannamei.
