Abstract

This study is aimed at exploring the effects of Bacillus coagulans NRS 609 on the growth performance, intestinal health, antioxidant activity, and immune response in common carp (Cyprinus carpio L.) by colonizing the intestinal tract with the beneficial strain. Gavage B. coagulans with GFP-tag at 109 CFU/mL into common carp for 7 days. Results indicated that B. coagulans were maintained in the intestine for at least 14 days. Four groups fed B. coagulans at different levels of inclusion, including 0 (CK), 1 × 10 7 (A), 1 × 10 8 (B), and 1 × 10 9 (C) CFU/g of feed for 8 weeks. Experimental groups showed significantly better growth performance than the control ( P < 0.05 ). The treatment groups had higher digestive enzyme activity, villus height, and muscle thickness than the control ( P < 0.05 ). Supplementation with B. coagulans also altered the composition of the intestinal flora. In addition, an enhancement of the antioxidant enzyme and a reduction of malondialdehyde in the liver were observed with the addition of B. coagulans ( P < 0.05 ). Moreover, the cytokines of IL-1β and IL-12, IL-10, and TGF-β, significant upregulation in experimental groups ( P < 0.05 ). Based on the results, the optimal level of B. coagulans was 107 CFU/g in diets for common carp.

凝固芽孢杆菌NRS 609有益定殖对鲤鱼生长性能、肠道健康、抗氧化能力和免疫应答的影响

本研究旨在探讨凝固芽孢杆菌NRS 609在鲤鱼(Cyprinus carpio L.)肠道定殖对鲤鱼生长性能、肠道健康、抗氧化活性和免疫应答的影响。以109 CFU/mL的gfp标签灌胃普通鲤鱼7天。结果表明，凝固芽孢杆菌在肠道中至少维持了14天。四组分别饲喂0 (CK)、1 × 10.7 (A)、1 × 10.7 (B)、1 × 10 9 (C) CFU/g的不同水平的凝血B菌，持续8周。试验组的生长性能显著优于对照组(P < 0.05)。各处理组的消化酶活性、绒毛高度和肌肉厚度均高于对照组(P < 0.05)。补充凝固芽孢杆菌也改变了肠道菌群的组成。此外，添加凝固双歧杆菌可提高肝脏抗氧化酶水平，降低丙二醛含量(P < 0.05)。各组细胞因子IL-1β、IL-12、IL-10、TGF-β均显著上调(P < 0.05)。综上所述，鲤鱼饲料中凝固芽胞杆菌的适宜水平为107 CFU/g。

期刊介绍： Aquaculture Nutrition is published on a bimonthly basis, providing a global perspective on the nutrition of all cultivated aquatic animals. Topics range from extensive aquaculture to laboratory studies of nutritional biochemistry and physiology. The Journal specifically seeks to improve our understanding of the nutrition of aquacultured species through the provision of an international forum for the presentation of reviews and original research papers. Aquaculture Nutrition publishes papers which strive to: increase basic knowledge of the nutrition of aquacultured species and elevate the standards of published aquaculture nutrition research. improve understanding of the relationships between nutrition and the environmental impact of aquaculture. increase understanding of the relationships between nutrition and processing, product quality, and the consumer. help aquaculturalists improve their management and understanding of the complex discipline of nutrition. help the aquaculture feed industry by providing a focus for relevant information, techniques, tools and concepts.
