dc.description.abstractThe fermentation products of <em>Astragalus</em> have been acknowledged for their ability to enhance immune functions. This study assessed the impact of incorporating <em>Astragalus</em>, fermented with <em>Lactobacillus plantarum</em> and <em>Bacillus coagulans</em>, on crucian carp's growth, disease resistance, and immunological characteristics. The experimental groups were fed with common feed (C), C + <em>Astragalus</em> (A), A + <em>Lactobacillus plantarum</em> (AL), A + <em>Bacillus coagulans</em> (AB), and AL + <em>Bacillus coagulans</em> (ALB). The fermented products were mixed with common feed at a 1:99 ratio, and crucian carp were fed 2% of their body weight for four weeks, with sampling conducted on days 3, 7, 14, 21, and 28. Disease resistance was evaluated using <em>Aeromonas hydrophila</em> (<em>A. hydrophila</em>) at a concentration of 0.2 mL (1.0×10^7 CFU/mL). The final weights in the AL, AB, and ALB groups significantly increased compared to the C group. The ALB group exhibited elevated serum albumin levels, alkaline phosphatase, intestinal lipase, protease enzyme, C3, and IgM gene expression compared to the C group. At the same time, alanine aminotransferase, aspartate aminotransferase, and glucose contents were significantly reduced. The survival rate significantly increased in all experimental groups after treatment with <em>A. hydrophila</em>. In conclusion, <em>Astragalus</em> products fermented with <em>Lactobacillus plantarum</em> and <em>Bacillus coagulans</em> could effectively improve crucian carp's growth, disease resistance, and immune response.
