Abstract：
:Seven known species of rumen ciliates and mixedEntodinium spp. showed association with plant particles in rumen fluid in vitro. Association was greater with fresh particles than with hay, and substantially decreased when the water-soluble components of the particles were removed, suggesting that the water-soluble components may be responsible for the association. The association was rapid and maximal between 5 and 35 min (depending on the ciliate species) after exposure to the particles, and involved major transfers of ciliate populations and biomass from the liquid phase to the solid phase of the system. The most rapid and largest population transfers to the particles from the rumen fluid were shown by the holotrich ciliates, where transfers of up to 97% of the population were recorded. Association with plant particles by all species examined occurred within the pH range 5.5-7.5, and decreased with time when the particles were incubated in rumen contents in vivo. The ciliate biomass transferring from the liquid to the solid phase varied with the composition of the ciliate population.
