This study was conducted to evaluate the effects of dietary supplementation with shrimp soluble extract (SSE) on growth performance, feed utilization, innate immunity and digestibility of Pacific white shrimp Litopenaeus vannamei. A basal diet (Con) was formulated and three other diets were prepared with SSE supplementation at different levels of 1, 2 and 4% (designated as SSE1, SSE2 and SSE4, respectively). Triplicate groups of shrimp (1.20±0.01 g) were fed one of the experimental diets for 6 weeks. At the end of the feeding trial, growth performance and feed utilization of the shrimp were significantly improved by dietary supplementation of SSE4 compared to those of shrimp fed the Con diet. Shrimp fed SSE4 diet had significantly higher phagocytic activity than shrimp fed the Con diet. Dietary supplementation of SSE improved the protein and dry matter digestibility of shrimp. These results indicate that SSE can be used as a functional additive in the diets for Pacific white shrimp.
