外文摘要：The present study evaluated the effects of supplementation with sodium alginate-coated Clostridium butyricum (SACB) on growth, immune response, and intestinal health of Litopenaeus vannamei following the replacement of fishmeal with cottonseed protein concentrate (CPC). The freeze-drying method was used for bacterial agent preparation, with the optimal ratio of freeze-dried protectant being 15% skimmed milk, 12% β-cyclodextrin, 8% glucose, and 0.5% dipotassium hydrogen phosphate. Six isonitrogenous and isolipid diets were formulated, with one serving as the control group (CG, 25% fishmeal content). The remaining five diets were formulated as fishmeal replacement groups (CPC replacing 40 % of fishmeal). The content of SACB in the alternative groups was 0% (SACB0), 0.06% (SACB1), 0.24% (SACB2), 0.96% (SACB3) and 3.84% (SACB4), respectively. The results showed that SACB improved the growth performance (P > 0.05). MDA activity was significantly inhibited in serum and hepatopancreas after SACB addition (P ? 2024, The Authors.
