Factors stimulating migration of holotrich protozoa into the rumen.
نویسندگان
چکیده
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 کاملEffect of progressive inoculation of fauna-free sheep with holotrich protozoa and total-fauna on rumen fermentation, microbial diversity and methane emissions
Rumen methanogenesis represents an energy waste for the ruminant and an important source of greenhouse gas; thus, integrated studies are needed to fully understand this process. Eight fauna-free sheep were used to investigate the effect of successive inoculation with holotrich protozoa then with total fauna on rumen methanogenesis. Holotrichs inoculation neither altered rumen fermentation rate ...
متن کاملStudy of methanogen communities associated with different rumen protozoal populations
Protozoa-associated methanogens (PAM) are considered one of the most active communities in the rumen methanogenesis. This experiment investigated whether methanogens are sequestrated within rumen protozoa, and structural differences between rumen free-living methanogens and PAM. Rumen protozoa were harvested from totally faunated sheep, and six protozoal fractions (plus free-living microorganis...
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 ...
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...
