Dietary supplementation of Adonis-derived astaxanthin enhances antioxidant capacity and immune response in Litopenaeus vannamei
Litopenaeus vannamei were fed diets supplemented with 0, 60, 90 and 120 mg/kg of Adonis amurensis-derived astaxanthin (AX) for 21 days. Intestinal morphology, muscle fatty acid composition, oxidative stress, and immune-related parameters were measured. The results showed that the AX-120 group exhibi...

| Summary: | Litopenaeus vannamei were fed diets supplemented with 0, 60, 90 and 120 mg/kg of Adonis amurensis-derived astaxanthin (AX) for 21 days. Intestinal morphology, muscle fatty acid composition, oxidative stress, and immune-related parameters were measured. The results showed that the AX-120 group exhibited the best growth performance, improved gut structure, and higher levels of ARA and EPA in muscle (P < 0.05). Antioxidant capacity was enhanced, with significant increases in T-AOC, ACP, AKP and TNOS activities (P < 0.05), CAT activity decreased (P < 0.05). SOD activity significantly decreased in the AX120 group (P < 0.05). Immune-related gene expression results show that the mRNA expression of Toll-1, Toll-2, CAT and proPO was significantly downregulated in the AX90 and AX120 groups (P < 0.05), and LZM and SOD in the AX120 group were also significantly downregulated (P < 0.05). This study provides a theoretical basis for the application of Adonis amurensis-derived AX in aquaculture. |
