This research aims to evaluate how different levels of Macleaya cordata extract affect growth performance, antioxidant capacity, and immune function in juvenile red claw crayfish.
Juvenile crayfish (initial weight 0.22 ± 0.02 g) were fed diets with varying levels of Macleaya cordata extract for eight weeks.
Six diet groups included control (0 g/kg) and five levels (0.01 to 0.15 g/kg MCE).
The study assessed growth, muscle composition, antioxidant enzyme activities, and stress response under microcystin-LR.
Dietary supplementation with 0.02–0.04 g/kg MCE significantly increased SOD, GPx, PO activities, and total antioxidant capacity, reducing MDA levels.
0.04 g/kg MCE significantly improved survival under microcystin-LR stress, with increased mRNA expression of antioxidant enzymes.
Overall, 0.04 g/kg MCE enhanced antioxidant capacity, immunity, and stress resistance in crayfish.
