Bacteria that colonize the mammalian intestine collectively possess a far larger repertoire of
degradative enzymes and metabolic capabilities than their hosts. Microbial fermentation of …

Weaning is a critical event in the pig's life cycle, frequently associated with severe enteric
infections and overuse of antibiotics; this raises serious economic and public health concerns. …

The rumen is a complex ecosystem composed of anaerobic bacteria, protozoa, fungi,
methanogenic archaea and phages. These microbes interact closely to breakdown plant material …

Ruminant production is under increased public scrutiny in terms of the importance of cattle
and other ruminants as major producers of the greenhouse gas methane. Methanogenesis is …

Aim: To examine the effect of concentrate and yeast additive on the number of cellulolytic
bacteria in the rumen of sheep. Methods and Results: Fibrobacter succinogenes, …

A close symbiotic relationship exists between the intestinal microbiota and its host. A critical
component of gut homeostasis is the presence of a mucus layer covering the gastrointestinal …

Ruminants have a unique ability to derive energy from the degradation of plant polysaccharides
through the activity of the rumen microbiota. Although this process is well studied in vitro…

Protozoa are commensal eukaryotes in the rumen of herbivores. Protozoa are large
producers of hydrogen, which is utilized by methanogenic archaea to produce methane, a …

The potential of dietary supplements of 2 live yeast strains (Saccharomyces cerevisiae) or
camelina oil to lower ruminal methane (CH 4 ) and carbon dioxide (CO 2 ) production and the …

The valorization of fibrous feed sources by ruminants is possible thanks to their unique
digestive system involving an intensive preliminary ruminal fermentation step prior to a more …
