“…At 13 weeks, only the cofactor and vitamin metabolism pathways in the FRS group were more abundant due to the higher abundance of Bacteroides and Ruminococcaceae uncultured bacterium, while the abundance of translation pathways in the NRS group was higher due to the presence of Subdoligranulum and Brachyspira , implying that the differences in functional pathways of microorganisms in the ceca of ducks between the FRS and NRS groups gradually decreased over time. As discussed previously, the colonization of intestinal microflora is a process that changes with age [ 29 ]; thus, differential metabolic pathways and microorganisms also undergo a gradual stabilization process. When ducks enter the youth period and the intestinal environment becomes relatively stable, the influence of the FRS and NRS systems on duck intestinal development and microorganisms can be revealed.…”

Background Rearing systems can affect livestock production directly, but whether they have effects on intestinal growth states and ceca microorganisms in ducks is largely unclear. The current study used Nonghua ducks to estimate the effects of rearing systems on the intestines by evaluating differences in intestinal growth indices and cecal microorganisms between ducks in the floor-rearing system (FRS) and net-rearing system (NRS). Results The values of relative weight (RW), relative length (RL) and RW/RL of the duodenum, jejunum, ileum and ceca in the FRS were significantly higher than those in the NRS during weeks 4, 8 and 13 (p < 0.05). A total of 157 genera were identified from ducks under the two systems, and the dominant microorganisms in both treatments were Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria at the phylum level. The distribution of microorganisms in the ceca of the two treatments showed significant separation during the three time periods, and the value of the Simpson index in the FRS was significantly higher than that in the NRS at 13 weeks (p < 0.05). Five differential microorganisms and 25 differential metabolic pathways were found in the ceca at week 4, seven differential microorganisms and 25 differential metabolic pathways were found in the ceca at week 8, and four differential microorganisms and two differential metabolic pathways were found in the ceca at week 13. Conclusions The rearing system influences duck intestinal development and microorganisms. The FRS group had higher intestinal RL, RW and RW/RL and obviously separated ceca microorganisms compared to those of the NRS group. The differential metabolic pathways of cecal microorganisms decreased with increasing age, and the abundance of translation pathways was higher in the NRS group at week 13, while cofactor and vitamin metabolism were more abundant in the FRS group.

Background Rearing systems can affect livestock production directly, but the effects of floor-reared systems (FRSs) and net-reared systems (NRSs) on the intestinal growth states and microbial diversity in the cecum of ducks are largely unclear. Methods The ducklings in this study were randomly divided into FRS and NRS groups, weighed at 4, 8 and 13 weeks, respectively, then the duodenum, jejunum, ileum and cecum were sampled and measured, and the content of cecum were analyzed by 16S RNA. Results The values of relative weight (RW), relative length (RL) and RW/ RL of four intestinal segments in FRS were significantly higher than that in the NRS during week 4, 8 and 13 (p < 0.05). A total of 157 genus were identified from ducks under the two systems,the dominant microorganisms in both groups were Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria at phyla level. The distribution of microorganisms in cecum of two groups showed significant separation in three time periods, and the value of Simpson index in FRS was significantly higher than NRS at 13 weeks (p < 0.05).Five differential microorganisms and 25 differential metabolic pathways were found in the cecum at week 4, 7 differential microorganisms and 25 differential metabolic pathways were found in the cecum at week 8, and 4 differential microorganisms and 2 differential metabolic pathways were found in the cecum at week 13. Conclusions There were differences in intestinal growth and microorganism between FRS and NRS ducks.

“…In recent years, the intestinal microbiota has been verified that it plays a vital role in the health of the host, as it can control the proliferation of pathogenic bacteria present in the intestinal tract, regulate the host metabolism and physiology, regulate the absorption of nutrients and stimulate the immune system ( Shi et al, 2022a ). Hence, the intestine is not merely a vital organ responsible for the absorption of nutrients but also a major site of host immunity ( Ran et al, 2020 ). Studies have shown that FAM can regulate the fecal microbiota of Arbor acre , improve its antioxidant properties and promote its growth ( Qiao et al, 2018b ).…”

In order to understand the effects of fermented Astragalus membranaceus (FAM) on the liver and intestinal health of tiger grouper (Epinephelus fuscoguttatus), this study was conducted. This study evaluates the effects of different levels of FAM on liver and intestinal tissue structure, serum biochemical parameters, intestinal digestive enzyme, and microbiota structure of tiger grouper. Fish were fed with diets (crude protein ≥ 48.0%, crude fat ≥ 10.0%) with five levels of FAM (L1:0.25%, L2: 0.5%, L3: 1%, L4: 2% and L5: 4%) in the experimental groups and a regular diet was used as the control (L0: 0%) for 8 weeks. Compared with AM, the protein content of FAM was significantly changed by 34.70%, indicating that a large amount of bacterial protein was produced after AM fermentation, and its nutritional value was improved. FAM had significant effects on the growth performance of tiger grouper (p < 0.05). The high-density lipoprotein cholesterol (HDL-C) was highest in L4 group, being significantly different from L0 group. The area and diameter of hepatocytes were lowest in L3 and L4, and the density of hepatocyte was highest in L4 group and relatively decreased in L5 group. The mucosal height and muscular thickness were highest in L3 group. The intestinal microbiota structure of tiger grouper was changed under the intervention of FAM. The lower abundance of potential pathogenic bacteria and higher abundance of probiotics colonization in the L4 group showed that the dose of FAM had the best effect on improving the health of intestinal microbiota. This study indicates that the addition of FAM in the feed contributes to liver health, improves intestinal morphology, and regulates the intestinal microbiota of tiger grouper. The addition ratio of 1%–2% is better for intestinal and liver health, and a high addition ratio will cause liver damage. Our work will provide a reference for the addition and management of FAM in the aquaculture industry.
