Rumen bacterial cluster identification and its influence on rumen metabolites and growth performance of young goats

Exploring the Rumen Microbiota and Serum Metabolite Profile of Hainan Black Goats with Different Body Weights before Weaning

“…This was further supported by Zhao et al [40], who confirmed through in vitro fermentation tests that Prevotellaceae_UCG-001 contributes to lignocellulose degradation and elevates VFA concentrations. Moreover, our study revealed a positive correlation between the relative abundance of Prevotella, Prevotellaceae_UCG-003, and butyrate levels, echoing the findings of Wang et al [41] in young goats, who also reported a positive correlation between the abundance of these bacteria and the concentrations of acetate and butyrate. These findings collectively suggest that the enriched presence of VFA-producing bacteria, including Prevotellaceae_UCG-001, Prevotellaceae_UCG-003, Prevotellaceae_UCG-004, and Prevotella, in the HBW goat kids is instrumental in enhancing rumen fermentation ability and the development of the rumen epithelium.…”

The effect of Phyllanthus emblica (Amla) fruit supplementation on the rumen microbiota and its correlation with rumen fermentation in dairy cows

“…The present study examines the effects of fresh Phyllanthus emblica (Amla) fruit, which is rich in hydrolyzable tannins, phenolic acids, flavonoids, and other compounds ( Tilahun et al, 2022b ), on rumen microbial composition, as well as its correlation with rumen fermentation. Rumen microbial populations are critical for their digestive processes, nutrient intake, and overall health ( Gao et al, 2022 ; Wang G. et al, 2023 ). Our research revealed that the core microbiota in the rumen is dominated by three phyla, namely, Firmicutes, Bacteroidota, and Actinobacteriota, which make up approximately 95.24% of the total microbial population ( Figure 2A ).…”

“…Furthermore, Oscillospiraceae NK4A214 group has a positive correlation with the concentration of total VFA and the molar proportion of propionate in ruminal fermentation from the degradation of complex carbohydrates found in plants (Konikoff and Gophna, 2016) and is thought to play a role in fiber degradation in the rumen due to its abundant production of endo-1, 4-beta-xylanase, and cellulase genes (Yi et al, 2022). A study by Wang G. et al (2023) reported that the Oscillospiraceae NK4A214 group produces propionate and butyrate in goats, which is consistent with our results. However, another study by Guo et al (2023) found a positive correlation between the group comprising NK4A214 and the concentration of acetic acid in calves, which could be due to variations in feed and species and underscores the need for further research in this area.…”

“…In addition, in our laboratory work, the supplementation of Amla fruit powder at 5 g per day improved the antioxidant capacity and immune response of preweaning dairy calves ( Nguse et al, 2022 ). Research findings suggest that the rumen bacterial population is associated with production performance in dairy cows, including milk quality and feed efficiency ( Wang G. et al, 2023 ). Our previous research on dairy cow performance has prompted us to investigate further the potential effects of Amla fruit on rumen microbes that may contribute to performance enhancement at varying dose levels.…”
