Metabolic Hydrogen Flows in Rumen Fermentation: Principles and Possibilities of Interventions

open access: yesFrontiers in Microbiology, 2020
Rumen fermentation affects ruminants productivity and the environmental impact of ruminant production. The release to the atmosphere of methane produced in the rumen is a loss of energy and a cause of climate change, and the profile of volatile fatty ...

The complete genome sequence of the rumen bacterium Butyrivibrio hungatei MB2003

open access: yesStandards in Genomic Sciences, 2017
Butyrivibrio hungatei MB2003 was isolated from the plant-adherent fraction of rumen contents from a pasture-grazed New Zealand dairy cow, and was selected for genome sequencing in order to examine its ability to degrade plant polysaccharides.

Quasar optical variability: searching for interband time delays [PDF]

open access: yes, 2008
Aims. The main purpose of this paper is to study time delays between the light variations in different wavebands for a sample of quasars. Measuring a reliable time delay for a large number of quasars may help constraint the models of their central ...

Inhibition of Rumen Methanogens by a Novel Archaeal Lytic Enzyme Displayed on Tailored Bionanoparticles

open access: yesFrontiers in Microbiology, 2018
Methane is a potent greenhouse gas, 25 times more efficient at trapping heat than carbon dioxide. Ruminant methane emissions contribute almost 30% to anthropogenic sources of global atmospheric methane levels and a reduction in methane emissions would ...

Milk fatty acid composition and associated rumen lipolysis and fatty acid hydrogenation when feeding forages from intensively managed or semi-natural grasslands [PDF]

open access: yes, 2005
In order to evaluate the effect of replacing intensive forage by semi-natural grassland products on rumen lipid metabolism and milk fatty acid composition, four lactating and rumen canulated Holstein cows were used in a 4×4 Latin square design.

Rumen fluke in Irish sheep: prevalence, risk factors and molecular identification of two paramphistome species [PDF]

open access: yes, 2016
peer-reviewedBackground Rumen flukes are trematode parasites found globally; in tropical and sub-tropical climates, infection can result in paramphistomosis, which can have a deleterious impact on livestock. In Europe, rumen fluke is not

Proteolysis in the Sheep Rumen by Whole and Fractionated Rumen Contents [PDF]

open access: yesJournal of General Microbiology, 1960
SUMMARY: The proteolytic activity of the whole rumen fluid of sheep does not depend on the diet of the animals. The optimum pH value for proteolysis lies between 6 and 7, with an irregular maximum at about pH 6·5. All fractions of rumen contents (protozoa, large bacteria and small bacteria) show activity. Proteolytic activity can be demonstrated in the

Cultivation and sequencing of rumen microbiome members from the Hungate1000 Collection

open access: yesNature Biotechnology, 2018
Productivity of ruminant livestock depends on the rumen microbiota, which ferment indigestible plant polysaccharides into nutrients used for growth. Understanding the functions carried out by the rumen microbiota is important for reducing greenhouse gas ...

Solid diet manipulates rumen epithelial microbiota and its interactions with host transcriptomic in young ruminants

open access: yesEnvironmental Microbiology, 2021
Summary Solid diet supplementation in the early life stages of ruminants could improve rumen microbiota and tissue development. However, most studies focus on bacteria in the rumen content community. The microbiota attached on rumen epithelium are rarely
