“…In fact, it is currently known that dietary yam supplementation can enhance gastrointestinal function and regulate the non-specific immune response (Chen et al, 2015;Jeon et al, 2006 and many evidences have indicated that the complex and dynamic microbial community has an important contribution to the body health (Peng et al, 2019;Zhang et al, 2020;Zheng et al, 2020).…”

“…Intestinal flora is regarded as the body's external organ or second genome (Stephens, Arhire, & Covasa, 2018; Zhu, Wang, & Li, 2010), and many evidences have indicated that the complex and dynamic microbial community has an important contribution to the body health (Peng et al., 2019; Zhang et al., 2020; Zheng et al., 2020). Previous studies have shown that herbal additives can change the composition of intestinal bacterial communities of fish (Büyükdevecia et al., 2018; Meng et al., 2019; Wu, Yeh, Hsueh, Yang, & Chu, 2018).…”

“…It contains many ingredients, such as steroidal saponins including dioscin, gracillin, furostanol, starch, mucopolysaccharides, dioscorin as a storage protein, amino acids and phenanthrene derivatives (Jeon et al., 2006; Wu, Zhu, Zheng, & Sheng, 2011). The results of pharmacological studies showed that yam has certain beneficial effects on certain vertebrates, such as promoting digestion, immunomodulation, antioxidant defence and anti‐inflammation (Meng et al., 2019; Qiao, Zhang, & Li, 2010; Shin et al., 2006; Wang, Liu, Wang, Chen, & Meng, 2020; Zhang et al., 2020). However, few studies on the effect of yam on aquatic animals were reported.…”

The intensive and semi-intensive cultivation is widely used in aquaculture and easily causes disease outbreaks bringing about the loss of aquatic products. Furthermore, factors including overcrowding, sudden changes of temperature, the deterioration of water quality, and inadequate feeding and management could result in immunosuppression in aquatic animals and thus increasing the susceptibility to certain infectious diseases (Awad & Awaad, 2017). In order to prevent and cure the infectious diseases, some antimicrobials have been extensively used in aquaculture industries. However, antibiotics and some chemotherapy treating diseases inevitably lead to

“…Consistent with Miao et al [ 47 ] and He et al [ 48 ], we found that the abundances of metabolism were the highest in the rumen at KEGG level 1. The different abundances of environmental information processing and genetic information processing between two treatments suggested that varying levels of energy and protein in the diets could influence the biochemical processes of ruminal bacteria in goats at molecular and cellular levels [ 49 ]. Liu et al [ 50 ] also reported that the KEGG pathways involved in carbohydrate metabolism were highly enriched in the microbiota of individuals fed with high energy diets, which was consistent with our study.…”

This study was conducted to investigate the impacts of dietary energy and protein on rumen bacterial composition and ruminal metabolites. A total of 12 ruminal samples were collected from Shaanbei white cashmere goats which were divided into two groups, including high-energy and high-protein (Group H; crude protein, CP: 9.37% in dry matter; metabolic energy, ME: 9.24 MJ/kg) and control (Group C; CP: 8.73%; ME: 8.60 MJ/kg) groups. Thereby, 16S rRNA gene sequencing and a quantitative polymerase chain reaction were performed to identify the rumen bacterial community. Metabolomics analysis was done to investigate the rumen metabolites and the related metabolic pathways in Groups C and H. The high-energy and high-protein diets increased the relative abundance of phylum Bacteroidetes and genera Prevotella_1 and Succiniclasticum, while decreasing the number of Proteobacteria (p < 0.05). The dominant differential metabolites were amino acids, peptides, and analogs. Tyrosine metabolism played an important role among the nine main metabolic pathways. Correlation analysis revealed that both Prevotella_1 (r = 0.608, p < 0.05) and Ruminococcus_2 (r = 0.613, p < 0.05) showed a positive correlation with catechol. Our findings revealed that the diets with high energy and protein levels in Group H significantly altered the composition of ruminal bacteria and metabolites, which can help to improve the dietary energy and protein use efficiency in goats.

BackgroundRed swamp crayfish (Procambarus clarkii) is one of the important aquatic foods for human. Trace elements are indispensable for human to maintain health. They could be enriched by crayfish lived in benthic habitat. However, the trace essential element in crayfish was less reported. In this study, we investigated the trace elements of Fe, Mn, Cu, Zn and Se accumulation in red swamp crayfish.MethodsFifteen crayfishes in average, three samples of sediments and water were respectively collected in each location of the fifteen villages located on Hubei and Hunan province of China. Besides, fifteen individuals for red swamp crayfish (Procambarus clarkii), variegated carp (Hypophthalmichthys nobilis) and hairy crabs (Eriocheir sinensis) were respectively collected in the village of Zhutong of Hubei province in China. Inductively coupled plasma mass spectrometry (ICP-MS) was used to perform the examination of trace elements. SPSS software and Duncan test were employed to conduct statistical analysis, respectively.ResultsThe concentrations of the five elements were highest in haptopancreas, but two of them (Fe and Mn) were lowest in abdominal muscle. The concentration of Cu, Zn and Se in abdominal muscle was higher than those in exoskeleton. The concentrations of Cu and Se in abdominal muscle of crayfish from Ensi region was highest comparing to the other three regions. There was a highly significant positive correlation for the concentrations of Cu and Se between crayfish and environment. In addition, we found crayfish could specifically enrich Se element. The similar situations were also found in the two investigated freshwater animals variegated carp (Hypophthalmichthys nobilis) and hairy crabs (Eriocheir sinensis).ConclusionThe five essential elements were enriched in the abdominal muscle of crayfish, but no excess threshold of food safety standard. The supplement of selenium for human could be realized by consuming crayfish and other freshwater animals.
