This study was conducted to evaluate the effects of dietary heat-killed Lactobacillus plantarum and compound probiotics (GH35A GH35B) on growth performance, antioxidative capacity, intestinal morphology microbiota Litopenaeus vannamei. Shrimps (1.29 ± 0.01 g) were fed with five different diets: C (control, basal diet without probiotics), LP1 (basal supplemented 0.05% L. powder), LP2 0.1% T1 15% GH35A 1% T2 2% GH35B). After 28 days feeding trial, it observed that body weight gain (BWG), specific rate (SGR), condition factor (CF) somatic index (ISI) significantly higher in groups compared those group (p < 0.05). Compared control group, supplementation influenced activities total antioxidant capacity (T-AOC), superoxide dismutase (T-SOD), peroxidase (POD), polyphenol oxidase (PPO), acid phosphatase (ACP) alkaline (AKP) hepatopancreas.
