In vitro Inoculation of Fresh or Frozen Rumen Fluid Distinguishes Contrasting Microbial Communities and Fermentation Induced by Increasing Forage to Concentrate Ratio

Frontiers in Nutrition, 2022
In vitro rumen batch culture is a technology to simulate rumen fermentation by inoculating microorganisms from rumen fluids. Although inocula (INO) are commonly derived from fresh rumen fluids, frozen rumen fluids are also employed for the advantages of ...

Selection of plant oil as a supplemental energy source by monitoring rumen profiles and its dietary application in Thai crossbred beef cattle [PDF]

Asian-Australasian Journal of Animal Sciences, 2019
Objective The present study was conducted to select a plant oil without inhibitory effects on rumen fermentation and microbes, and to determine the optimal supplementation level of the selected oil in a series of in vitro studies for dietary application.

Microbial Rumen Fermentation

Journal of Dairy Science, 1981
With the ruminant animal, we have essentially two ecosystems, namely, the microbial ecosystem within the rumen and the animal's external environment. In dealing with the microbial ecosystem, we have made significant strides in the last few decades toward accomplishing the overall goal of ecology, which is to understand the relationships of organisms to

Evaluation of models to predict the stoichiometry of volatile fatty acid profiles in rumen fluid of lactating Holstein cows [PDF]

, 2011
Volatile fatty acids (VFA), produced in the rumen by microbial fermentation, are the main energy source for ruminants. The VFA profile, particularly the nonglucogenic (acetate, Ac; butyrate, Bu) to glucogenic (propionate, Pr) VFA ratio (NGR), is ...

Modulation of rumen bacterial community and feed utilization in camel and sheep using combined supplementation of live yeast and microalgae

Scientific Reports, 2022
The combination of live yeast and microalgae as feed supplementation could improve rumen fermentation and animal productivity. This study aimed to investigate the impact of a mixture of (YA) yeast (Saccharomyces cerevisiae) and microalgae (Spirulina ...

The inhibition of high ammonia to in vitro rumen fermentation is pH dependent

Frontiers in Veterinary Science, 2023
Ammonia is an important rumen internal environment indicator. In livestock production, feeding a large amount of non-protein nitrogen to ruminants will create high ammonia stress to the animals, which increases the risk of ammonia toxicity.

Simulating the effects of grassland management and grass ensiling on methane emission from lactating cows [PDF]

, 2009
A dynamic, mechanistic model of enteric fermentation was used to investigate the effect of type and quality of grass forage, dry matter intake (DMI) and proportion of concentrates in dietary dry matter (DM) on variation in methane (CH(4)) emission from ...

Can a fermentation gas mainly produced by rumen Isotrichidae ciliates be a potential source of biohydrogen and a fuel for a chemical fuel cell? [PDF]

, 2010
Bacteria, fungi and protozoa inhabiting the rumen – the largest chamber of the ruminants’ stomach, release large quantities of hydrogen during the fermentation of carbohydrates.

Research advances on nutritional regulation of rumen methanogenesis in ruminants

Siliao yanjiu, 2021
Methane emission from the rumen is one of the major sources of greenhouse gas (GHG). 2% to 12% of the gross energy consumed is converted to enteric CH4 during rumen fermentation.

Modelling the impact of the macroalgae Asparagopsis taxiformis on rumen microbial fermentation and methane production

Peer Community Journal, 2021
Background: the red macroalgae Asparagopsis taxiformis is a potent natural supplement for reducing methane production from cattle. A. taxiformis contains several anti-methanogenic compounds including bromoform that inhibits directly methanogenesis.
