This study aimed to demonstrate the effects of dietary glutathione (GSH) on growth, intestinal antioxidant capacity, histology, gene expression, and microbiota in juvenile triploid rainbow trout (). Different diets (G0-control, G100, G200, G400, and G800) containing graded levels of GSH (0, 100, 200, 400, and 800mgkg) were fed to triplicate groups of 30 fish (initial mean weight 4.12±0.04g) for 56days. G400 had significantly improved weight gain and feed conversion rate. Based on the broken-line regression analysis, the optimum dietary GSH level was 447.06mgkg. Catalase and superoxide dismutase activities were significantly higher in G200-G800. G200 had significantly lower malondialdehyde content. The height of the intestinal muscular layer in G400 was significantly higher than that of the control group. Intestinal PepT1 and SLC1A5 gene expression was significantly increased, and the highest was observed in G400. TNF-α, IL-1β, IL-2, and IL-8 expression were significantly decreased than that of G0. Next-generation sequencing of the 16S rDNA showed a significant difference in alpha diversity whereas no differences in beta diversity. On the genus level, LefSe analysis of indicator OTUs showed , , , , , , , and were associated with the treatment diet, whereas , , , , , , , , , and were associated with the control diet. In summary, feeding juvenile triploid 200-800mgkg GSH improved growth and intestinal health.

Probiotics exert a diverse range of immunomodulatory effects on the human gut immune system. These mechanisms encompass strengthening the intestinal mucosal barrier, inhibiting pathogen adhesion and colonization, stimulating immune modulation, and fostering the production of beneficial substances. As a result, probiotics hold significant potential in the prevention and treatment of various conditions, including inflammatory bowel disease and colorectal cancer.

This study evaluated the effect of wheat germ oil (WGO), Bacillus subtilis, and their combination on growth performance, immune response, nutrient digestibility, intestinal microbial, oxidative status, and gene expression in heat-stressed broilers. Four hundred one-day-old male Ross 308 broilers were distributed into five pens (20 birds/pen) in four experimental groups: a control (CON) without additives, WGO group fed diet with WGO at 200 mg.kg, BS group fed diet with B.

Intestinal stem cells (ISCs) and Paneth cells (PCs) reside at the bottom of the crypts of Lieberkühn in the small intestine. Recent studies have shown that the transcription factor Mist1, also named BHLHA15, plays an important role in the maturation of PCs. Since there is an intimate interaction between PCs and ISCs, we speculated that the loss of Mist1 could impact these two neighboring cell types.

The current study had aimed to assess the long-term dietary supplementation with Melaleucae aetheroleum, tea tree essential oil (TTO). The impact on growth performance, biochemical indices, immune function, oxidant/antioxidant activity, gene expression, histopathology, and resistance against Aeromonas sobria in Nile tilapia (Oreochromis niloticus) was investigated. Four groups (with five replicates; G1 (control group, G2, G3, and G4) of Nile tilapia received diets enriched with TTO (doses of 0.
