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

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 ...

Lightweight Rumen Cannula for Rumen Motility Studies
Journal of Dairy Science, 1965 Abstract Rumen fistula plugs and cannulas have been developed for various purposes. If the ingesta is to be completely removed from the rumen, a large fistula and plug are necessary (2). For the periodic removal of small volumes of rumen ingesta, the plug of Komarek and Leffel (3) is very sturdy and satisfactory; however, we have had trouble making ...

Microbial Cell Factories, 2012 The rumen is one of the most complicated and most fascinating microbial ecosystems in nature. A wide variety of microbial species, including bacteria, fungi and protozoa act together to bioconvert (ligno)cellulosic plant material into compounds, which can be taken up and metabolized by the ruminant.

Mobile Genetic Elements, 2012 Plasmids are episomally replicating genetic elements which carry backbone genes that are important for their replication and maintenance within their host, and accessory genes that might confer an advantage to their host in its ecological niche. As such, they are often perceived as a powerful evolutionary force, which horizontally introduces new traits

MICROBIAL PROTEIN PRODUCTION IN THE RUMEN OF STEERS FED LOW QUALITY FORAGE SUPPLEMENTED WITH VARIOUS LEVELS OF BARLEY GRAIN OR BARLEY GRAIN PLUS PROTEIN [PDF]
, 2006 An experiment was conducted to examine the effects of increasing intake of barley grain or barley grain plus protein as supplement on microbial crude protein (MCP) production, efficiency of microbial crude protein production (eMCP) in the rumen of ...

Accumulation of trans C18:1 fatty acids in the rumen after dietary algal supplementation is associated with canges in the Butyrivibrio communitytrans [PDF]
, 2008 Optimization of the fatty acid composition of ruminant milk and meat is desirable. Dietary supplementation of algae was previously shown to inhibit rumen biohydrogenation, resulting in an altered milk fatty acid profile.

Influence of Inoculum Content on Performance of Anaerobic Reactors for Treating Cattle Manure using Rumen Fluid Inoculum [PDF]
, 2009 Biogas productions of cattle manure using rumen fluid inoculums were determined using batch anaerobic digesters at mesophilic temperatures (room and 38.5 oC). The aim of this paper was to analyze the influence of rumen fluid contents on biogas yield from

Nitrogen Metabolism in the Rumen [PDF]
Journal of Dairy Science, 2005 Protein metabolism in the rumen is the result of metabolic activity of ruminal microorganisms. The structure of the protein is a key factor in determining its susceptibility to microbial proteases and, thus, its degradability. Ruminal protein degradation is affected by pH and the predominant species of microbial population. Ruminal proteolytic activity
