This study evaluated the effects of dietary synbiotics using Sargassum horneri celluclast hydrolysate (SCH, prebiotic) and Lactobacillus plantarum (LP, probiotic) on the growth, feed utilization, immunity and disease resistance of Penaeus vannamei. Six diets were formulated: Control (S0), 1% and 2% SCH-supplemented diets (S1 and S2), and the same diets each supplemented with 1% LP (S0LP, S1LP and S2LP). Eighteen tanks (180 L) were randomly assigned to the six dietary treatments, with three replicates of 25 shrimp (2.01 g) per tank, for 6 weeks. Growth and feed utilization were significantly increased in the S1LP group compared with those in the S0 group. Nitro blue tetrazolium activity was significantly enhanced in the S0LP group compared with that in the S0 group. The S1, S1LP and S2LP groups showed significantly improved lysozyme activity. Superoxide dismutase and catalase activities were significantly enhanced by the S1, S0LP, S1LP and S2LP diets. Notably, shrimp fed the S1, S0LP, S1LP and S2LP diets showed significantly higher disease resistance to Vibrio harveyi than those fed the S0 diet. Therefore, the combined supplementation of dietary 1% SCH with 1% LP improves the growth, immune and antioxidant capacity and disease resistance of P. vannamei against V. harveyi.
