Aspects physio-pathologiques de la thiamine (vitamine B1) chez les ruminants

open access: yesINRAE Productions Animales, 1994
Cette revue envisage d’abord la production microbienne, l’absorption et l’utilisation métabolique de la thiamine chez le ruminant sain ainsi que les effets d’une synthèse insuffisante de thiamine sur l’activité microbienne du rumen.

Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]

open access: yes, 2004
The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

Characterization of the Octadecenoic Acids in Rumen Digesta and Rumen Bacteria

open access: yesJournal of Dairy Science, 1966
Abstract Analysis of the lipids from total rumen digesta with respect to time after feeding did not reveal any changes in total lipid, fatty acid concentrations, types of fatty acids, or the concentration of trans -octadecenoic acids. The octadecenoic acids from the rumen digesta consisted of 75% trans acids, trans -11-octadecenoic acid being the ...

Rumen Modeling: Rumen Input-Output Balance Models

open access: yesJournal of Dairy Science, 1975
Two models of rumen fermentative relationships expressed as systems of simultaneous linear equations and based on requirements for maintenance of balances of elementary imput and output and metabolic pathways are presented in matrix format consistent with solution by linear programs.

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]

open access: yes, 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.

Measurement of methane emission from sheep by the sulphur hexafluoride tracer technique and by the calorimetric chamber: failure and success

open access: yesAnimal, 2008
The aim of this study was to evaluate the sulphur hexafluoride (SF6) tracer technique for methane (CH4) emission measurement in sheep. Ten cryptorchid Romney sheep were involved in two indoor trials (T1 and T2), where daily CH4 emissions were ...
