Feeding Laboratory Mice: Comparing a Standard Versus a Purified Diet – Marked Effects on Digestive Physiology

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Diet composition and processing have a major impact on its utilisation by the animal, as is known from farm and pet animal species. This includes effects on energy and nutrient digestibility, the intermediary metabolism, and the intestinal microbiome, with all the resulting impacts. For laboratory animals, data is scarce on influencing factors

Dietary β-hydroxybutyric acid improves the growth performance of young ruminants based on rumen microbiota and volatile fatty acid biosynthesis

Frontiers in Microbiology
IntroductionThe ketone body β-hydroxybutyric acid (BHB) plays critical roles in cellular proliferation and metabolic fuel utilization; however, its effects on the rumen microbiota remain unknown.MethodsHere, three doses of BHB (low, medium, and high ...

Rumen microbiota regulates IMF deposition in Xizang sheep by activating the PPARγ transcription factor: a rumen-muscle axis perspective

mSystems
The interaction between microbiota and muscle by the rumen-muscle axis and its impact on sheep meat flavor has received little attention. This study selected Xizang sheep under summer and autumn grazing conditions as models for different rumen bacteria ...

Rumen fluid transplantation affects growth performance of weaned lambs by altering gastrointestinal microbiota, immune function and feed digestibility

Animal, 2021
Although rumen fluid transplantation (RT) has been developed to confer benefits for adult ruminants by altering gastrointestinal tract microbiota, the question remains whether RT can also benefit weaned lambs.

Gut Lactate Boosts Ruminococcus via Histone Lactylation to Mediate Time‐Restricted Feeding Protection in Crohn's Disease

Advanced Science, Volume 13, Issue 33, 15 June 2026.
TRF enriches Ruminococcus, a bacterial genus producing SCFAs, and activates the epithelial HIF‐1α signaling pathway. This mechanism protects the colonic mucosa from inflammatory insults in colitis models. Mechanistically, gut lactate production during starvation and refeeding mediates H4K12la, which increases SLC9A3 expression and creates an acidic gut

Synergetic action between the rumen microbiota and bovine health

Microbial Pathogenesis, 2018
Host-rumen-microbe interactions are essential components of many physiological processes, and therefore can affect ruminant health. Classical knowledge of rumen microbiology is based on culture-dependent methodologies, which only account for 10-20% of the rumen bacterial communities. While, the advancement in DNA sequencing and bioinformatics platforms

Age Influences the Bacterial Composition of Samples From Buffaloes in the Marajó Archipelago, Pará, Brazilian Amazon

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Milk microbiomes showed similar composition in young and adult buffaloes. Despite distinct microbial profiles among matrices, shared bacterial families indicate microbial interaction between milk, faeces, calf spittle and soil. ABSTRACT Buffalo milk stands out for its nutritional qualities and is mainly produced in Brazil in the Amazon region ...

The Regulation of Ruminal Short-Chain Fatty Acids on the Functions of Rumen Barriers

Frontiers in Physiology, 2019
The rumen barriers, constituted by the microbial, physical and immune barrier, prevent the transmission of pathogens and toxins to the host tissue in the maintenance of host-microbe homeostasis.

Full‐Length 16S and 18S rRNA Long‐Read Sequencing Reveals Gut Microbiome Diversity in the European Brown Hare (Lepus europaeus)

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Full‐length 16S and 18S rRNA Oxford Nanopore sequencing of large intestine contents from 30 healthy European brown hares revealed broad gut microbiome diversity. An 80% identity threshold detected substantially greater taxonomic richness than 95%, emphasizing the value of long‐read sequencing in wildlife microbiome research. ABSTRACT The European brown

Antibiotic pretreatment minimizes dietary effects on reconstructure of rumen fluid and mucosal microbiota in goats

MicrobiologyOpen, 2018
We used 16S rRNA gene sequencing to examine the posteffects of antibiotic treatment on the structure and metabolism of rumen microbiota. Twelve goats were randomly assigned into two groups, with one group receiving intramuscular streptomycin injection at
