This research aims to evaluate the effects of dietary supplementation with Oscillatoria limnetica on shrimp growth and immune response.
Shrimps were fed diets with varying levels of O. limnetica (0.0 to 3.0 g/kg) for 12 weeks.
Growth rates and immune responses were measured before and after a challenge with Vibrio harveyi.
Enzymatic activities and mRNA expression were assessed to evaluate digestive and immune functions.
Shrimps fed the highest O. limnetica diet (OL3.0) had significantly better growth and enzyme activities than the control group (OL0).
Mortality after bacterial challenge was 83.3% in the control group versus 46.7% in OL3.0 group (p < 0.05).
Increased antioxidant activity and upregulation of immune-related genes were observed in shrimps fed O. limnetica.
