“…Proteobacteria were also tolerant to secondary plant metabolites, such as camphor. The Proteobacteria RA was enhanced by the addition of camphor in ruminal fermentation [23,24,47], which was consistent with our results. The RA of Sordariomycetes also significantly increased with the Cinnamomum camphora biomass addition.…”

This research explored the effects of the addition of low doses of aromatic plant biomasses (APBs) on the microbial community and carbon source decomposition in compost. APBs were reported to be capable of altering the composition and function of microbial communities in many environments. However, the effects of APB addition on the compost carbon source metabolism, a process highly linked to the microbial community of compost, were still unclarified, especially when added in small doses. In this study, Cinnamomum camphora biomass was added to the initial compost of Stropharia rugosoannulata cultivation materials, in a mass ratio of 0%, 1%, 2%, and 3%, respectively. The variation in the carbon source contents, the microbial community composition, and the related enzyme activities of the end compost products were measured. The results showed that Cinnamomum camphora biomass addition significantly altered the content of cellulose, hemicellulose, lignin, and protein of compost products, but did not affect the starch and soluble sugar content. Meanwhile, the addition significantly reduced lignin peroxidase and cellulase activities, but increased xylanase and laccase activities, and had no effect on magnesium peroxidase and polyphenol oxidase. Both the bacterial and fungal community compositions were significantly altered by the addition, though the alpha diversity indexes were not significantly changed. The relative abundance of Proteobacteria and Sordariomycetes was significantly increased by the addition, while Acidobacteria, Chloroflexi and Eurotiomycetes significantly decreased. Structural equation modeling found that the variation in the bacterial community composition (0.464 standard total effect) provided a higher contribution to lignocellulose degradation, rather than the fungal community (0.365 standard total effect). A co-occurrence network analysis further revealed that the trade-off between lignin peroxidase and laccase activity, which was induced by the relative abundance variation in Proteobacteria, Actinobacteriota, and Firmicute members, was the main driver in the lignocellulose decomposition variation. This research provides a new insight into the recycling of APB waste, and offers an improvement to mushroom cultivation material compost.

“…Some secondary metabolites (condensed tannins, saponins, essential oils, and flavonoids) of FNHs, (Cichorium L., Allium L., Gentiana L., and Morus L.), have been proved to improved the intestinal absorption of nutrients (Patra et al, 2017;Ibrahim et al, 2021). Gentiana straminea and Ligularia virgaurea contain many secondary metabolites, including monoterpenoids, diterpenoids, triterpenes, sesquiterpenes, simple secoiridoid glycoside, flavonoids, and iridoid glycosides, which may have antagonistic or synergistic on livestock performance and gastrointestinal flora (Xie et al, 2022;Cui et al, 2023), the whole herbage additions could enhance livestock performance and rumen microbes simultaneously. The "combined effect" consists of three aspects: firstly, a FNH normally contains a variety of active components which have a kind of synergistic or antagonistic effect on livestock performance as a wholeness; secondly, there were differences in the types and contents of various FNH and active components in diets, which had positive, negative or no effect on livestock; finally, the productive performance of livestock responds to the active component of FNH, which is reflected in the regulation of immune performance, digestion and metabolism, and growth performance, etc.…”

“…Some plants (e.g., Gentiana straminea , Ligularia virgaurea , and Cistanche deserticola ) are often not favored by herbivores because of their unique taste or poor palatability ( Liu X. et al, 2020 ; Xie et al, 2022 ; Cui et al, 2023 ). These undesirable plants are abundant all year round and thus can be used as non-conventional feed resources or “functional native herbage (FNH).” The whole plant or some organs of FNH are rich in secondary metabolites throughout the whole year or during the growing season.…”

Compared to traditional herbage, functional native herbage is playing more important role in ruminant agriculture through improving digestion, metabolism and health of livestock; however, their effects on rumen microbial communities and hindgut fermentation are still not well understood. The objective of present study was to evaluate the effects of dietary addition of Allium mongolicum on bacterial communities in rumen and feces of claves. Sixteen 7-month-old male calves were randomly divided into four groups (n = 4). All calves were fed a basal ration containing roughage (alfalfa and oats) and mixed concentrate in a ratio of 60:40 on dry matter basis. In each group, the basal ration was supplemented with Allium mongolicum 0 (SL0), 200 (SL200), 400 (SL400), and 800 (SL800) mg/kg BW. The experiment lasted for 58 days. Rumen fluid and feces in rectum were collected, Rumen fluid and hindgut fecal were collected for analyzing bacterial community. In the rumen, Compared with SL0, there was a greater relative abundance of phylum Proteobacteria (p < 0.05) and genera Rikenellaceae_RC9_gut_group (p < 0.01) in SL800 treatment. In hindgut, compared with SL0, supplementation of A. mongolicum (SL200, SL400, or SL800) decreased in the relative abundances of Ruminococcaceae_UCG-014 (p < 0.01), Ruminiclostridium_5 (p < 0.01), Eubacterium_coprostanoligenes_group (p < 0.05), and Alistipes (p < 0.05) in feces; Whereas, the relative abundances of Christensenellaceae_R-7_group (p < 0.05), and Prevotella_1 (p < 0.01) in SL800 were higher in feces, to maintain hindgut stability. This study provided evidence that A. mongolicum affects the gastrointestinal of calves, by influencing microbiota in their rumen and feces.

“…Ruminococcaceae_UCG-005 and Ruminococcaceae UCG-010 was a member of the Ruminococcus family, which might facilitate the degradation of insoluble plant cell walls in the intestinal tract [ 65 ]. In the present study, the relative abundance of Ruminococcaceae_UCG-005 was higher in G4H or G8H group compared to the CONT group, which might indicate an improved ability to degrade cellulose and hemicellulose due to the combination with grazing, thus resulting in higher dietary fiber intake, as Ruminococcus had a substantial set of hemicellulase and oligosaccharide-degrading enzymes [ 59 ]. Moreover, Ruminococcus bacteria played an important role in short-chain fatty acid production [ 66 ] and immunity in ruminants [ 27 ].…”

This study investigated the effects of three feeding systems, indoor feeding (CONT), indoor feeding with time-restricted grazing artificial pasture (4 h/day, G4H), and indoor feeding with an eight-hour daily grazing artificial pasture (G8H), on the growth performance, serum metabolites, ruminal fermentation, and fecal microbiota composition of lambs. Average daily gain showed a tendency (p = 0.081) to be higher for the G4H group compared with the CONT group. Moreover, feeding systems did not have a significant effect on most of the serum biochemical indicators in lambs. Concentrations of serum glutathione peroxidase and immunoglobulins (IgA, gG, and IgM) were significantly lower (p < 0.01) in the CONT group. Additionally, a tendency towards higher levels of volatile fatty acids, acetate, and butyrate was found in animals of the G4H group compared to the CONT group. Furthermore, fecal microbiota composition was altered in G4H and G8H groups, resulting in the increased relative abundance of Firmicutes and Ruminococcaceae UCG-005, as well as the decreased relative abundance of Ruminobacter compared with the CONT group. Overall, these results suggest that indoor feeding with restricted grazing time does not significantly affect fattening performance or rumen fermentation but enhances antioxidation and immune function activity and also alters fecal microbiota composition.
