The direction of the fermentation processes and level of the volatile fatty acids (VFA) in liquid content of bull’s rumen, when feeding them different forms of cellulose-containing fodder, were studied. It was established, that total amount of VFA, that comes from rumen to blood and tissues, influences significantly energetic supply of ruminants organism. Some VFA, which are coming from rumen to blood and tissues, are able to influence the direction metabolism processes and synthesis of particular components of ruminants’ organism. It was shown, that influence of different forms of cellulosecontaining fodder on direction metabolism processes in rumen and VFA assay in its fluid depends from time relative to beginning of feeding. It was established also, that different forms of cellulose-containing fodder are able to regulate fermentation processes in bull’s rumen under condition of feeding to them young grass an combined fodder, as well as total amount and assay of some VFA in ruminal fluid depends from form of cellulose-containing fodder in ration. Keywords: fermentation processes, volatile fatty acids, rumen, fiber-containing feed, ruminants.
