In vitro effects of saponins, tannins and lipids on rumen fermentation and intestinal health markers in a ruminant weaning context

Italian Journal of Animal Science
Dairy ruminants often experience physiological disturbances during the post-weaning, including suboptimal rumen fermentation due to an underdeveloped rumen microbiota, and diarrhoea associated with intestinal inflammation and oxidative stress. This study

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Rumen Mycobiome Thiamine Metabolism Contributes to Subacute Rumen Acidosis Tolerance in Goats Through Enhancing Epithelial Cell Proliferation via IGFBP2/IGF1 Axis Activation

Exploration, EarlyView.
Schematic illustration of the mechanism underlying the differences between SARA‐susceptible and SARA‐tolerant dairy goats fed a high‐concentrate diet. SARA‐susceptible goats (HCS) exhibit low rumen pH and metabolic decline, characterized by epithelial inflammation.

Effect of medicinal and food homologous plants polysaccharides on animal nutrition and health: A review

Food Biomacromolecules, EarlyView.
Abstract As one of the most important components of foods, animal meat provides a lot of protein, fat, and energy for humans. However, nutrition and health of animals directly affect the healthiness of human, especially antibiotic residues in animals induced by abuse of antibiotics.

In vitro rumen methane output of forb species sampled in spring and summer

Agricultural and Food Science, 2012
The chemical composition, in vitro rumen fermentation variables and methane (CH4) output of a range of common forb species sampled in spring and summer, and grass silage (14 treatments in total), were determined in this study.

Development of an Alternative In Vitro Rumen Fermentation Prediction Model

Animals
The aim of this study is to identify an alternative approach for simulating the in vitro fermentation and quantifying the production of rumen methane and rumen acetic acid during the rumen fermentation process with different total mixed rations.

High-Gossypol Whole Cottonseed Exhibited Mediocre Rumen Degradability and Less Microbial Fermentation Efficiency than Cottonseed Hull and Cottonseed Meal with an In Vitro Gas Production Technique

Fermentation, 2022
To explore whether or not the gossypol varied in cottonseed by-products affect rumen degradability and fermentation efficiency, an in vitro cumulative gas production experiment was applied with mixed rumen microorganism to compare rumen fermentation ...

[The rumen fermenter].

Reproduction, nutrition, developpement, 1986
The two main pregastric compartments of ruminants (rumen and reticulum) can be compared to an anaerobic fermenter which allows them to use energetic and nitrogen substrates which are indigestible by monogastric animals. The aim of this bibliographic review is to describe the main features (characteristics) of this fermenter, focusing on the role of ...

The role of the gut microbiome in the regulation of high‐altitude adaptation

iMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...
