A.  aPassage of protozoa and valatile fatty acids from the rumen of the sheep and from a continuous in vitro fermentation system.h[electronic resource]  c1974  aI. A procedure for sampling digesta from within the omasal canal of sheep given a variety of roughage diets was used to enable comparison to be made of the composition of effluent from the reticulo-rumen with that of rumen fluid. 2. Concentrations of protozoa in effluents, relative to a soluble marker continuously infused intraruminally, were usually less than 20 yo of corresponding rumen fluid concentrations. It was estimated that the amount of protozoal nitrogen leaving the rumen represented less than 2% of dietary N. 3. Passage of volatile fatty acids (VFA) from the rumen in effluent was less than 75% of that indicated by rumen concentrations. 4. A continuous, in vitro fermentation system was developed, in which outputs of protozoa were comparable with in vivo outputs.  aAcetates  aChromium  aDigestion  aFatty acids  aFermentation  aOmasum  aParasitology  aRuminant nutrition  aSheep  aSodium  aFisiologia  aNutrição  aOvino  aCarbon radioisotopes  aEdetic acid  aEquipment and supplies  aHydrogen-ion concentration  aIn vitro techniques  aSpectrophotometry atomic1 aPILGRIM, A.
