The Role of Ciliate Protozoa in the Rumen
First described in 1843, Rumen protozoa with their striking appearance were assumed to be important for the welfare of their host. However, despite contributing up to 50% of the bio-mass in the rumen, the role of protozoa in rumen microbial ecosystem remains unclear. Phylogenetic analysis of 18S rDNA libraries generated from the rumen of cattle, sheep, and goats has revealed an unexpected diver...
متن کاملDiurnal changes and effect of ration on concentrations of the rumen ciliate Charon ventriculi.
Charon ventriculi comprised over 30% of the total protozoa observed in rumen contents of a Flamenga cow fed Rhodes grass hay (Chloris gayana). Both percentage of composition and concentration decreased markedly when concentrate was added to the ration or the animal was fed in pasture. Although C. ventriculi is classified as a holotrich, concentrations of this species in the rumen appear to foll...
متن کاملFactors stimulating migration of holotrich protozoa into the rumen.
The effects of feeding and various reticular infusions on ruminal holotrich concentrations were studied in an attempt to identify possible factors stimulating their migration into the rumen. It was concluded that glucose entering the reticulo-rumen shortly after feeding could stimulate migration of holotrich protozoa.
متن کاملIntracellular Prokaryotes in Rumen Ciliate Protozoa: Detection by Confocal Laser Scanning Microscopy
In situ hybridization of rumen ciliate protozoa with 165 ribosomal RNA fluorescent oligonucleotide probes specific for Archaea and Bacteria provided semi-quantitative indication of the location, type and extent of prokaryotic colonization of various protozoal species. The isotrichid holotrich ciliates generally carried a smaller load of intracellular microorganisms than did the entodiniomorphid...
متن کاملComparison of duodenal flow and digestibility in fauna-free sheep inoculated with Holotrich protozoa, Entodinium monofauna or total mixed protozoa population.
The present results are the last part of a series of experiments conducted in this laboratory on metabolism of major individual rumen ciliate protozoa species and their combinations in sheep. These species were inoculated into the rumen of fauna-free (FF) sheep to study digestibility of dietary fibre and duodenal flow of N. Sixteen rumen- and duodenum-cannulated FF sheep were divided into four ...
