Although β-glucan has diverse benefits for fish health, the potential adverse impacts of excessive supplementation are poorly understood. This study investigated optimal dosage coral trout and explored effects supplementation. The results revealed that moderate (1) significantly enhanced weight gain rate specific growth (SGR); (2) improved intestinal villus length (0.10%), muscle thickness (0.05–0.15%), α-amylase chymotrypsin activities (0.05–0.15%); (3) increased liver catalase (CAT), glutathione reductase (GR), alkaline phosphatase, complement 3, immunoglobulin M (IgM), lysozyme, serum superoxide dismutase, CAT, peroxidase, GR, total antioxidant capacity, acid 4, IgM reduced malondialdehyde contents; (4) upregulated genes in associated with copper-zinc dismutase (SOD-1), manganese (SOD-2), GSH-Px1a, ACP6, AKP, LZ-c, IgM, C3, C4-b. However, 0.20% inhibited performance compared 0.10% β-glucan. Thus, represents promoting growth, activity, immune responses trout, while higher levels weakened these beneficial effects. With an SGR established by a cubic regression analysis, level maximal is 0.082%. provides new insights into health on fish.

This study used largemouth bass (initial average weight: 33.33 ± 1.8 g) to explore the effects of adding different brown algae extracts feed on fish's growth, immunity and intestinal health. Six groups were set up: a control (Group A), 0.1% sodium alginate B), oligotriosaccharide I C), II D), 0.2% powder E) enzymatic product F), with three replicates 35 fish each, 56-day feeding experiment. Results: Compared Group A, Groups C, D F had higher specific growth rate lower coefficient (p < 0.05). enhanced serum SOD activity; increased antioxidant enzyme activity decreased MDA content All experimental LZM levels 0.05), no IgM difference > In intestine, treatment α-amylase 0.05) lipase trypsin tallest villi, B thickest muscular layer villus width was similar among The fewer pathogenic bacteria, improved microorganism diversity richness conclusion, can promote capacity immunity. is better for development flora improvement.

Enterococcus faecium inhabits animal gastrointestinal tracts and has been demonstrated to benefit livestock poultry, but its effects on soft‐shelled turtles remain unexplored. The present work investigates the of probiotic E. intestinal microbiota barrier structure, immune function, antioxidant capacity turtle. Twenty‐four juvenile Pelodiscus sinensis were divided into two groups: control (fed a basal diet) treatment diet supplemented with , 3.3 × 10 8 CFU/g feed), over period 6 weeks. We found that did not promote growth at feeding level, resulted in significant alterations microbial community increased abundance Romboutsia Clostridium_sensu_stricto_1 reduction Aeromonas ( p < 0.05). notably enhanced villus height/crypt depth, width, density intestine. group exhibited 1.50‐fold increase goblet cells count 1.18‐fold higher muscular layer thickness compared group. also improved an ratio plasma neutrophils lymphocytes total number leukocytes after probiotics, upregulation levels toll‐like receptor 4 (TLR 4), lysozyme, interleukin 1 β (IL‐1 ), tumor necrosis factor α (TNF‐ immunoglobulin A (IgA) intestine, as well level hepatic M (IgM). Additionally, supplementation boosted capabilities, including catalase (CAT) glutathione peroxidase (GPx) activity reduced (GSH) intestine GSH spleen. Our study demonstrates beneficial supplemental overall health turtles, particularly enhancing their function capacity.
