“…Bacterial communities in the RRPP‐supplemented group clustered together and separately from those of the control group. The bacterial phyla Fusobacteria, Proteobacteria, Firmicutes, Verrucomicrobia and Bacteroidetes were dominant in all of the assayed groups, which is consistent with previous studies on several freshwater fish (Wu et al, ; Wu, Tian, Wang, Li, & Zou, ; Zhou et al, ). However, the relative abundances of these dominant bacterial phyla were altered when Luciobarbus capito were fed RRPP.…”

In this study, we assessed the effects of Radix Rehmanniae Preparata polysaccharides (RRPP) on the digestive enzymes, morphology, microbial communities and mucosal barrier function of the intestine of Luciobarbus capito. Fish were fed different amounts of RRPP (0, 0.05, 0.1, 0.2 and 0.4%) for 60 days. The results revealed that intestinal amylase and trypsin activities significantly increased after the 0.2% RRPP treatment (p < .05). Increases in intestinal fold height, wall thickness and fold density were observed in Luciobarbus capito fed an RRPP‐supplemented diet, and the best effect was observed in the proximal intestine. Sequencing of the bacterial 16S rRNA V4 region showed that dietary RRPP reduced intestinal microbial community richness and species diversity. Fusobacteria, Proteobacteria, Firmicutes and Verrucomicrobia were the dominant bacterial phyla in the intestine of Luciobarbus capito. Dietary RRPP affected the overall microbial community and increased the abundance of the genus Cetobacterium. Moreover, RRPP significantly upregulated the expression of occludin, zonula occludens (ZO)‐1 and claudin‐c in the intestine (p < .05). In summary, supplementing the diet of Luciobarbus capito with RRPP can improve digestive enzymes activities and intestinal morphology, modulate the microbial composition and enhance intestinal mucosal barrier function.

“…Yeast culture, and its cell wall extract containing 1,3-1,6 βglucan and mannan oligosaccharide are the important natural growth promoters and immunomodulators with a strong positive effect on modern livestock and poultry production (Li et al 2005). Brewer's yeast (S. cerevisiae) has been proven to have a positive effect on growth performance, immune responses or anti-stress status of pigs, goats, poultry, cattle, and fish species (Huige 2006;Muthusamy et al 2011;Chollom et al 2017;Zhou et al 2018).…”

The objective of this study was to determine the effects of brewer's yeast hydrolysate (BYH, Saccharomyces cerevisiae) on laying hens. A total of 288 Hy-line Brown laying hens were randomly assigned to 1 of 6 treatments with 8 replications (6 birds per replication). The treatment diets were supplemented with BYH at levels of 0, 0.05, 0.10, 0.50, 1.0 or 3.0%, respectively. The supplementation of BYH diets led to a significant linear (P < 0.05) effect on egg production, egg weight and egg mass during 37-41 and 42-46 weeks. The supplementation of BYH diets also led to a significant linear increase observed in internal egg quality: albumen height (37-41 and 42-46 weeks), Haugh unit (42-46 weeks), and yolk colour (37-41 and 42-46 weeks), and a significantly linear increase in eggshell thickness (P < 0.05) during 37-41 and 42-46 weeks. A linear increase was observed on dry matter and nitrogen at 46 weeks of laying hens, and linear increase and linear decrease were detected for Lactobacillus and E. coli at 46 weeks of laying hens, respectively. As a result, dietary BYH had beneficial effects on egglaying performance, egg quality, nutrient digestibility, and excreta microflora in laying hens.

“…Furthermore, scale cortisol concentrations were shown to reflect the stress history in teleosts, including milkfish [ 40 , 41 , 42 ]. Although many studies investigated biomarkers in fish with respect to environmental stressors or feeding strategies, only a very limited number of publications attempted to elucidate the interaction between gut microbiome composition and fish physiological biomarkers [ 43 ].…”

Effects of Thermal Stress on the Gut Microbiome of Juvenile Milkfish (Chanos chanos)

et al. 2020

Milkfish, an important aquaculture species in Asian countries, are traditionally cultured in outdoor-based systems. There, they experience potentially stressful fluctuations in environmental conditions, such as temperature, eliciting changes in fish physiology. While the importance of the gut microbiome for the welfare and performance of fish has been recognized, little is known about the effects of thermal stress on the gut microbiome of milkfish and its interactions with the host’s metabolism. We investigated the gut microbiome of juvenile milkfish in a thermal stress experiment, comparing control (26 °C) and elevated temperature (33 °C) treatments over three weeks, analyzing physiological biomarkers, gut microbiome composition, and tank water microbial communities using 16S amplicon sequencing. The gut microbiome was distinct from the tank water and dominated by Cetobacterium, Enterovibrio, and Vibrio. We observed a parallel succession in both temperature treatments, with microbial communities at 33 °C differing more strongly from the control after the initial temperature increase and becoming more similar towards the end of the experiment. As proxy for the fish’s energy status, HSI (hepatosomatic index) was correlated with gut microbiome composition. Our study showed that thermal stress induced changes in the milkfish gut microbiome, which may contribute to the host’s habituation to elevated temperatures over time.
