Tiger shrimp were fed commercial feeds without or with 2% organic acid blend (OAB).
Shrimp fed with 2% OAB showed higher protein, dry matter and phosphorus digestibility.
Shrimp fed organic acid diets showed higher survival after Vibrio challenge.
Higher shrimp survival may be due to enhanced immune response and lower bacterial infections.
Organic acids imparted hepatopancreatic protective properties against vibriosis.
