Summary: BC is a nutraceutical that can modulate intestinal microbiota. This study investigates the effects of BC diet supplementation on luminal and mucosa-associated microbiota in the jejunum, caecum, and colon of rabbits. Significant differences were found in the microbial composition of the three groups, especially in the caecum and colon of the 2.5% BC group. A functional prediction has revealed several altered pathways in BC groups, with particular reference to amino acids and lactose metabolism. Findings suggest that BC supplementation could positively affect the intestinal microbiota.

Summary: This study in a rabbit model showed that early introduction of solid food can accelerate gut microbiota maturation, and plant polysaccharides ingestion has a significant impact on the cecal microbiota.

Summary: This study investigated the origin of chicken gut microbiota in commercial production through microbiota analysis by 16S rRNA sequencing. It was found that neither eggshells nor feed served as major sources of gut microbiota for newly hatched chickens, and they must be colonised from additional sources such as air dust with spores of Clostridiales.

Summary: The addition of alfalfa meal and peanut vine supplements has a positive effect on the production performance and gut microbiota of meat rabbits, with the effect of alfalfa meal being better. The supplementation of alfalfa meal and peanut vine can increase the diversity and richness of the gut microbiota, improving the meat quality of meat rabbits.

Summary: This study found that the bacteria adherent to plant biomass in the donkey hindgut were different from those in the liquid phase, and bacteria associated with feed particles may mainly be responsible for plant fiber degradation.

Summary: This study investigated the effects of feeding insoluble fiber on the microbiota and metabolites of rabbits recovering from epizootic rabbit enteropathy. The results showed that a low-fiber diet may increase the short-chain fatty acid content and species diversity index values in the caecum, while decreasing species diversity levels in fecal samples.

Summary: This study investigated the effects of hydrolyzed soya lecithin on the growth performance, caecal microbiota, and fat depots in pre-breeding primiparous rabbits. The results showed that adding 0.5% soya lecithin to the diet increased feed intake and energy storage in adipocytes, and improved the fatty acid profile of periovarian fat.

Summary: Increasing dietary starch intake can affect rumen fermentation, microbiota composition, methanogenesis, and fiber digestibility in ruminants. Manipulating ruminal hydrogen (H2) and pH levels through increased starch intake resulted in changes in methane concentration, volatile fatty acid concentration, and microbial populations in the rumen. Ruminal pH was found to be closely associated with fiber digestibility, while ruminal dissolved hydrogen (dH2) levels were associated with methane concentration.

Summary: In developed countries, there is a growing emphasis on healthy dietary habits and the development of functional foods enriched with vitamins and prebiotics to improve overall health. Modified dietary fibers with little impact on taste have been created to provide benefits similar to prebiotics.

Summary: Dietary pulses, such as dry beans and lentils, are a good source of fiber and can easily be incorporated into regular diets to improve gut health. The resistant starch derived from pulses plays a crucial role in shaping the gut microbiota and promoting metabolic health. However, more research is needed to explore the potential benefits of pulses and their resistant starch on aging-associated gut health.

Summary: This study reveals the formation of stable glycan-utilizing machines, called utilisomes, which consist of glycoside hydrolases and bacterial outer membrane proteins in Bacteroides thetaiotaomicron. The structures of these utilisomes show the mechanism and function of the interactions between their components.

Summary: This study investigated the effects of glyphosate and its commercial herbicide formulations on the gut microbiota of rats. The results showed that Roundup formulations had dose-dependent effects on bacterial and fungal diversity, while glyphosate alone only affected bacterial diversity. Moreover, glyphosate and its Roundup formulations caused profound changes in the gut microbiome composition, potentially influencing the long-term toxicity, carcinogenicity, and multigenerational effects of glyphosate-based herbicides.

Summary: The importance of dietary components, such as fibers and prebiotics, in modulating intestinal microbiota has been increasing since their role in metabolism was understood. Certain types of resistant starch are considered as potential prebiotic components, although not all studies have achieved positive results.

Summary: Pueraria lobata starch (PLS) has high hot stability and potential prebiotic effect, increasing the abundance of beneficial bacteria. The study demonstrates that PLS can effectively alleviate inflammation and liver damage in non-alcoholic fatty liver disease (NAFLD) by improving gut dysbiosis.

Summary: The study found that both magnesium hydride (MGH) and coated-magnesium hydride (CMG) have similar positive effects on the microbiota and metabolites of broiler cecal in an in vitro fermentation model. MGH promotes the abundance of SCFA-producing bacteria, while CMG increases the concentration of certain organic acids. Both MGH and CMG have significant impacts on metabolites.
